Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many cheap essay writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online. If you’re wondering how to check paper for plagiarism, it’s nothing complicated at all! Simply visit our site, paste your whole essay into the relevant text box or upload the text file, click on Check For Plagiarism, and you’ll get accurate plagiarism results in a matter of seconds. You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my essay for plagiarism and then to hire a professional paper writer to fix your task quickly if you're busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original. All the sources that your essay matches are listed based on how much similarity there is in your academic writing. And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue do assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly. Turning such a paper in can cause multiple problems, as your professor might think you haven’t done the work at all.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

Our plagiarism detector has a lot going for it. It makes plagiarism detection easier than ever before. Unlike copying and pasting each passage individually into Google, simply upload the whole file into our plagiarism checker free for students, and you don’t have to do anything else. All the matches are highlighted so you know what to change.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school. As a result, your grades will drastically improve when you check for plagiarism.

Check for unintentional plagiarism

Easily check your paper for missing citations and accidental plagiarism with the EasyBib plagiarism checker. The EasyBib plagiarism checker:

• Scans your paper against billions of sources.
• Identifies text that may be flagged for plagiarism.
• Provides you with a plagiarism score.

You can submit your paper at any hour of the day and quickly receive a plagiarism report.

What is the EasyBib plagiarism checker? 

Most basic plagiarism checkers review your work and calculate a percentage, meaning how much of your writing is indicative of original work. But, the EasyBib plagiarism checker goes way beyond a simple percentage. Any text that could be categorized as potential plagiarism is highlighted, allowing you time to review each warning and determine how to adjust it or how to cite it correctly.

You’ll even see the sources against which your writing is compared and the actual word for word breakdown. If you determine that a warning is unnecessary, you can waive the plagiarism check suggestion.

Plagiarism is unethical because it doesn’t credit those who created the original work; it violates intellectual property and serves to benefit the perpetrator. It is a severe enough academic offense, that many faculty members use their own plagiarism checking tool for their students’ work. With the EasyBib Plagiarism checker, you can stay one step ahead of your professors and catch citation mistakes and accidental plagiarism before you submit your work for grading.

Why use a plagiarism checker? 

Imagine – it’s finals week and the final research paper of the semester is due in two days. You, being quite familiar with this high-stakes situation, hit the books, and pull together a ten-page, last-minute masterpiece using articles and materials from dozens of different sources.

However, in those late, coffee-fueled hours, are you fully confident that you correctly cited all the different sources you used? Are you sure you didn’t accidentally forget any? Are you confident that your teacher’s plagiarism tool will give your paper a 0% plagiarism score?

That’s where the EasyBib plagiarism checker comes in to save the day. One quick check can help you address all the above questions and put your mind at ease.

What exactly is plagiarism? 

Plagiarism has a number of possible definitions; it involves more than just copying someone else’s work. Improper citing, patchworking, and paraphrasing could all lead to plagiarism in one of your college assignments. Below are some common examples of accidental plagiarism that commonly occur.

Quoting or paraphrasing without citations

Not including in-text citations is another common type of accidental plagiarism. Quoting is taking verbatim text from a source. Paraphrasing is when you’re using another source to take the same idea but put it in your own words. In both cases, it’s important to always cite where those ideas are coming from. The EasyBib plagiarism checker can help alert you to when you need to accurately cite the sources you used.

Patchwork plagiarism

When writing a paper, you’re often sifting through multiple sources and tabs from different search engines. It’s easy to accidentally string together pieces of sentences and phrases into your own paragraphs. You may change a few words here and there, but it’s similar to the original text. Even though it’s accidental, it is still considered plagiarism. It’s important to clearly state when you’re using someone else’s words and work.

Improper citations

Depending on the class, professor, subject, or teacher, there are multiple correct citation styles and preferences. Some examples of common style guides that are followed for citations include MLA, APA, and Chicago style. When citing resources, it’s important to cite them accurately. Incorrect citations could make it impossible for a reader to track down a source and it’s considered plagiarism. There are EasyBib citation tools to help you do this.

Don’t fall victim to plagiarism pitfalls. Most of the time, you don’t even mean to commit plagiarism; rather, you’ve read so many sources from different search engines that it gets difficult to determine an original thought or well-stated fact versus someone else’s work. Or worse, you assume a statement is common knowledge, when in fact, it should be attributed to another author.

When in doubt, cite your source!

Time for a quick plagiarism quiz! 

Which of the following requires a citation?

• A chart or graph from another source
• A paraphrase of an original source
• Several sources’ ideas summarized into your own paragraph
• A direct quote
• All of the above

If you guessed option E than you’d be correct. Correct punctuation and citation of another individual’s ideas, quotes, and graphics are a pillar of good academic writing.

What if you copy your own previous writing?

Resubmitting your own original work for another class’s assignment is a form of self-plagiarism, so don’t cut corners in your writing. Draft an original piece for each class or ask your professor if you can incorporate your previous research.

What features are available with the EasyBib plagiarism checker? 

Along with providing warnings and sources for possible plagiarism, the EasyBib  plagiarism checker works alongside the other EasyBib tools, including a grammar checker  and a spell checker . You’ll receive personalized feedback on your thesis and writing structure too!

The  plagiarism checker compares your writing sample with billions of available sources online so that it detects plagiarism at every level. You’ll be notified of which phrases are too similar to current research and literature, prompting a possible rewrite or additional citation. You’ll also get feedback on your paper’s inconsistencies, such as changes in text, formatting, or style. These small details could suggest possible plagiarism within your assignment.

And speaking of citations, there are also  EasyBib citation tools  available. They help you quickly build your bibliography and avoid accidental plagiarism. Make sure you know which citation format your professor prefers!

Great! How do I start? 

Simply copy and paste or upload your essay into the checker at the top of this page. You’ll receive the first five grammar suggestions for free! To try the plagiarism checker for free, start your EasyBib Plus three-day free trial.* If you love the product and decide to opt for premium services, you’ll have access to unlimited writing suggestions and personalized feedback.

The EasyBib plagiarism checker is conveniently available 24 hours a day and seven days a week. You can cancel anytime.  Check your paper for free today!.

💯 12 Online Plagiarism Checkers

🔗 references, 🤔 why use a plagiarism checker.

The issues of plagiarism and academic dishonesty become more and more relevant each year. According to some research , 92% of surveyed students stated that they had or knew someone who had cheated .

So, why does this happen?

The researchers have shed light on this phenomenon, and here are some of their statistics:

• 92% of those who plagiarized stated that they did so because they wanted better grades.
• 83% said that they cheated because of procrastination.
• 75% of respondents pointed out that they did not have enough time to finish their assignments.
• 33% have attempted to cheat due to their overloaded class schedule.
• 58% of the surveyed have plagiarized because they lacked an understanding of the subject.
• 50% had little or no interest in the subject.
• 25% of participants believe that anyone can cheat without any consequences.
• 17% of the interviewees cheated because of peer pressure.
• Another 17% think that it does not matter to the professor if their paper is plagiarized.

After taking all of these numbers into account, it is evident that a significant percentage of students commit acts of plagiarism for several main reasons. Among them are poor time management, concern for academic performance, and peer pressure.

Now that you know the causes of plagiarism, it will be beneficial to examine its different types. Generally, these can be divided into two groups: unintentional and intentional.

Intentional Plagiarism

When it comes to intentional plagiarism, it doesn’t necessarily mean that your paper copies the full document written by someone else. This is only one example of cheating out of many others.

Unintentional Plagiarism

Meanwhile, unintentional plagiarism may refer to:

• Forgetting to cite a source when describing something that is not common knowledge.
• Not citing information that you have paraphrased or summarized.
• Failing to use a proper citation style when documenting sources.
• Misquoting an author, even if it is appropriately cited in the paper.

When composing your paper, it is important to stay vigilant. This is why it is handy to utilize the help of our plagiarism checker (2000 words). Free detection software is a quick and easy way to confirm your paper’s originality.

🔍 How to Check for Plagiarism

As you work on your paper, you may start to ask yourself: How can I avoid plagiarism altogether?

Below, we have prepared some tips that will help you write a 100% original essay:

• Regulate your time. As mentioned earlier, procrastination and a full class schedule may lead to plagiarism. To stay on top of everything, don’t put off urgent tasks until tomorrow. Read up on time management techniques and figure out an efficient study method that works for you.
• Cite while you write. Get in the habit of citing sources in full as you write your paper. Firstly, doing this will save you plenty of time for putting together a bibliography. Second, it will significantly decrease the risk of an improper citation.
• Use only trusted sources. There are a lot of websites with questionable content. Even documents that seem scholarly at first could turn out to be another student’s paper. Ascertain that you understand the source and the ideas that it is trying to convey.
• Understand the difference between various citation styles. An improper citation may result in a penalty for plagiarism. So, make sure you rely on a high-quality reference guide and implement the correct style. Don’t forget to add quotation marks when using unchanged phrasing from the source.
• Use plagiarism scanners before you submit your paper. Even if you wrote your piece from scratch, we still advise you to double-check it. From time to time, you might unintentionally “borrow” a couple of phrases that appear in other works. Despite it being an accident, your professor might penalize your paper. To avoid this, you can use one of the online free plagiarism detectors.

Perhaps our free plagiarism checker (2000 words & more) wasn’t exactly what you were looking for. If you find yourself in need of a tool with slightly different features, this section is for you!

Below, we have prepared a list of 12 online plagiarism scanners , both chargeable and free. They will allow you to avoid similarities with other works on the Internet.

2. Grammarly

Grammarly is famous for its superior grammar-checking software. However, with a paid version, you’ll also get access to its plagiarism detector.

Did we mention that it’s free?

Viper , also known as ScanMyEssay, is a plagiarism detector supporting 56 languages. It checks your content against over 10 billion sources and can scan multiple files at once.

PlagAware offers high-quality plagiarism detection and checks your papers against over 70 billion sources! It has a free plan that allows you to scan 10 pages per month. Moreover, if you choose a premium plan, you pay only for the first check of every document, while subsequent scans of the revised versions are free.

9. Copyscape

Copyscape is a plagiarism detector that can check your paper against online sources and web pages. It doesn’t check your content against academic databases, books, scholarly journals, and offline sources. So, it’s suitable for online content creators and website owners, while students seeking to check academic writing should opt for something else.

10. Copyleaks

Copyleaks offers both free and paid accounts to its users. In both cases, you have to register to use this service. If you have a free account, you can upload up to 2,500 words per month and use two checks. You will also see the history of your previous plagiarism scans.

11. Quetext

Quetext is a user-friendly plagiarism checker that allows you to edit text directly within the tool and has a useful feature — a citation assistant. However, you can check only 500 words with their free plan. After exhausting this limit, you have to go premium. It can also fail to identify plagiarism from scholarly sources like student dissertations or journal articles.

12. SmallSEOTools

The last paper plagiarism checker tool in our list, SmallSEOTools , allows you to check up to 1000 words per search for free. The amazing thing about this tool is that it’s available in English, Chinese, Russian, Italian, French, Portuguese, Spanish, German, and Japanese languages.

Frequently asked questions

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker. Plagiarism checks can be bought separately — prices depend on the size of your document.

Similarities in your document are highlighted for quick and easy review. Each colour corresponds to a source in your Sources Overview at the right side of your report.

Information can often be found in more than one place. For this reason, other sources citing the same information you used can come up in your Sources Overview.

The important thing is to make sure you’ve cited the source of the material. Try to find the original source, but if you can’t find it, it’s best to cite the source where you found the information.

Scribbr’s free plagiarism checker estimates the risk of plagiarism by calculating the percentage of text in your document that’s similar to other sources.

A moderate or high risk of plagiarism means that the plagiarism software detected several similarities worth reviewing.

Note that similarities are not necessarily plagiarism. You will need to decide on your own whether your text needs revision or citation.

The free report tells you if your text contains potential plagiarism and other writing issues. The premium report gives you the resources you need to review issues in detail and resolve them.

Yes, Scribbr offers a limited free version of its plagiarism checker in partnership with Turnitin. It uses Turnitin’s industry-leading plagiarism detection technology and has access to most content databases.

Run a free plagiarism check

If you’re a university representative, you can contact the sales department of Turnitin .

If you’ve correctly cited all the sources you used, then you do not need to use a plagiarism checker before submitting your paper to your instructor. However, it is very easy to commit plagiarism accidentally, even if you’ve been very careful. To ensure that you didn’t forget to cite anything, you should use a plagiarism checker yourself.

A  plagiarism checker works by using advanced database software to scan for matches between your text and existing texts.

To help you decide which checker to use, we conducted in-depth research comparing popular plagiarism checkers to find out which one is best.

Best plagiarism checker comparison

Your work should not contain any  plagiarism . Even if your score is 1%, you will need to review each similarity and decide whether it’s necessary to revise your work.

But  contrary to popular belief, plagiarism checkers work by detecting not plagiarism, but similarities . Not all similarities found by the Scribbr Plagiarism Checker constitute plagiarism. Our check sometimes flags the following:

• Properly cited quotes
• In-text citations or your reference list
• Commonly used phrases

What should I do with a found similarity?

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2022.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.

The add-on AI Detector and AI Proofreader are only available in English.

The complete list of supported languages:

Scribbr’s  Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker , namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases .

The add-on AI detector is powered by Scribbr’s proprietary software.

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

• 99.3 billion current and historical webpages
• 8 million publications from more than 1,700 publishers such as Springer, IEEE , Elsevier, Wiley-Blackwell, and Taylor & Francis

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.

If your university uses Turnitin, the result will be very similar to what you see at Scribbr.

The only possible difference is that your university may compare your submission to a private database containing previously submitted student papers. Scribbr does not have access to these private databases (and neither do other plagiarism checkers).

Luckily, many papers, theses, and dissertations are also published in public databases that Scribbr does have access to.

Best Plagiarism Checkers Compared

Published on August 26, 2024 by Koen Driessen .

The best plagiarism checker should detect plagiarism the most accurately, even when the original phrasing has been altered. It should also provide a clear, comprehensive plagiarism report.

To identify the best plagiarism checker, we compared the performance of 12 checkers through an in-depth research process. We uploaded plagiarized texts that were either directly copied and pasted from multiple sources or edited to varying degrees. In total, we used 140 sources to construct our test documents.

Overview of total scores per plagiarism checker, based on the amount of detected plagiarism:

Table of contents

Our process for comparing checkers, 1. scribbr review , 2. plagaware review , 3. compilatio review , 4. prepostseo review , 5. grammarly review , 6. duplichecker review , 7. check-plagiarism review , 8. copyleaks review , 9. small seo tools review , 10. plagiarism detector review , 11. quetext review , 12. smodin review , frequently asked questions about plagiarism checkers.

In order to find the best plagiarism checker, we analyzed different aspects of the tools, focusing on both depth and breadth.

We based our analysis on the following factors:

• Access to the biggest and most varied database
• Ability to detect the most plagiarism for the most source types
• Ability to detect plagiarism when the plagiarized texts have been paraphrased
• Highest quality of matches
• Level of user-friendliness and trustworthiness

We used the same test documents, evaluation criteria, and data analysis for each tool in order to objectively compare the plagiarism results side by side. This ensured that the results required very little interpretation on our part.

“Catches plagiarism more accurately than any other checker”

• Finds the most plagiarism and works for edited texts, too
• Does not store or sell documents
• Offers a happiness guarantee and live support
• Offers a Self-Plagiarism Checker to check for self-plagiarism
• Offers a limited free version
• Quality comes at a price
• Cannot work directly in the tool

Quality of matches

Scribbr performed well for all source types relevant to students, such as journal articles and dissertations.

Most importantly, Scribbr’s checker was the most successful at detecting plagiarism in source texts that had been heavily edited to mimic accidental paraphrasing plagiarism.

Scribbr was also able to find full matches. This means the entire plagiarized portion is matched correctly to just one source.

The results are presented in a clear, downloadable overview. Different colors are used for different sources, making it easy for users to assess each plagiarism issue separately.

Issues can be fixed with Scribbr’s free Citation Generator , which generates proper citations for any missed or improperly cited sources.

Users can also choose to combine the Plagiarism Checker with the Self-Plagiarism Checker , which is unique to Scribbr. This tool allows users to upload their own unpublished documents in addition to the public database.

Instead of requiring users to subscribe to their services, Scribbr charges per plagiarism check ($19.95–$39.95, depending on the word count).

However, users are unable to work directly in the tool, and it is not possible to recheck your document for free.

Trustworthiness

Scribbr does not store the uploaded documents, sell them to third parties, or share them with academic institutions. Data is automatically deleted after 30 days, or students can opt to manually delete their document after the check.

Scribbr has live and responsive customer support to assist users in multiple languages. There is easy access to a plagiarism checker guide and other free resources about plagiarism.

Scribbr also has a happiness guarantee, where users receive a new check or refund if they aren’t satisfied for any reason.

• Detects most of the plagiarism
• Documents not stored in database
• Dashboard with a summary of analyzed documents
• Difficult to read PDF reports
• Does not work well for scholarly sources

PlagAware was often able to find full matches and attribute the text to the correct source. However, it performed poorly with heavily edited texts.

For sources that had been edited, the tool often highlighted the entire paragraph as plagiarized, not distinguishing the parts that had been paraphrased from those that had not.

The website report is easy to navigate as it uses different colors for sources. The tool has a function that tells you how many words a plagiarized section has and gives a similarity percentage.

Unfortunately, the downloadable report is confusing to read as it uses only one color for all sources.

Users pay per page of scanned text. A packet of 100 pages is €12.99 (USD prices not listed on the website).

According to their website, users can delete documents from their profile at any time. 

There is no live support, but there is a contact form and phone number that can be used to contact support.

• Credits can be used for multiple documents
• Scans against other documents you have uploaded
• Doesn’t highlight the plagiarized parts in the text
• Hard to review and resolve instances of plagiarism

Compilatio was able to find quite a few of the plagiarized sources, but it struggled if the source text had been heavily edited.

When it was able to identify a source, it was often correct, but the tool’s performance seemed to decline toward the middle and end of documents.

Compilatio’s downloadable report is very easy to read and clearly links to each plagiarized source. However, it is not clear which part of each paragraph is being marked as plagiarism, as the text is not highlighted.

The tool scans the text against other documents you have uploaded, which can help to avoid self-plagiarism.

Users can buy packages of credits starting at €4.99 (for 5,000 words). These credits can be used for multiple documents and are valid for 12 months after purchase. Monthly plans are also available.

Compilatio does not share or sell submitted documents, and the documents are not used as comparison material for other users.

There is no live support available, but they do provide a helpdesk with FAQs and a request form.

Discover Compilatio’s plagiarism checker

• Does not share documents with third parties
• Built-in tools to rewrite and paraphrase text
• Finds a relatively low percentage of plagiarism, especially for scholarly sources
• Sources are not color-coded

Prepostseo’s tool is sometimes able to find full matches and generally attributes plagiarized text to the correct source. However, with edited texts, it sometimes marks only part of a paragraph as plagiarized.

It missed many instances of plagiarism at all levels of editing, especially those that came from scholarly sources.

The online report does not use different colors to differentiate between different sources. It does link to the plagiarized source, though. However, the PDF report does not indicate in any way which text is from which source.

The tools offered by Prepostseo to eliminate plagiarism are nice, but they did not always function smoothly.

A basic subscription plan costs $10/month and includes plagiarism detection for 5,000 sentences.

There is a contact form on the website but no live support. Prepostseo does not store or share uploaded content.

Discover Prepostseo’s plagiarism checker

• Offers a language and citation assistant
• Does not sell or share documents with other parties
• Finds quite a low percentage of plagiarism
• 100,000 character limit (14,000–25,000 words)
• Same colors for different sources

Grammarly found a relatively low amount of plagiarism. It scored lower than 40% in all rounds of testing.

When it did find plagiarism, the tool was often able to find the right source. However, the matches were usually only partial and rarely included the entire plagiarized section.

The design is not very clear. As the tool is primarily used as a language checker, the plagiarism checker function is somewhat difficult to find. The tool uses the same color for all sources, making it hard to read. Additionally, you have to split longer texts into two parts in order for the scan to run.

The subscription comes with a language and style tool and offers a citation assistant that helps generate the missing citations. There is a 100,000 character limit per document uploaded. Additionally, there is a 150,000 total word limit per month for both the monthly ($30 per month) and the yearly plan ($12 per month).

For more information, you can read our in-depth  Grammarly review .

Grammarly does not store, sell, or share documents with other parties.

There is a support page with tips, tutorials, and FAQs, and it is possible to submit a question via a form. However, there is no live support.

• The format of the document is preserved in both the online and downloadable reports
• Maintains a history of your checked documents
• Was not able to find full matches
• The downloadable report is difficult to interpret

While DupliChecker was able to identify more than 40% of the plagiarized material, it was not able to identify full matches. That is, when entire sentences were plagiarized, it only identified part of the sentence as plagiarized material.

The tool is easy to use, with a clean interface. However, the scan took longer than average to run. In the downloadable report, plagiarized text is not connected to its source, which makes it difficult to identify exactly what text is plagiarized. DupliChecker does keep a history of users’ scans.

Subscription plans start at $5/week (for 10,000 words).

According to DupliChecker’s website, user documents are not saved. There is a contact form on the website but no live support.

• You can easily access previous scans
• You can rename documents
• Did not perform well at detecting plagiarized content, especially in edited documents
• Longer documents have to be divided in two
• Only one color used for matches

Check-Plagiarism found less than 40% of the plagiarized text in edited documents. The tool performed particularly poorly for scholarly sources. It was able to find some full matches but often returned only a partial match.

The report is difficult to read because red is used for every source and the formatting of the original is not preserved. In the PDF report, the sources are not linked directly from the text, which diminishes its usefulness. The document had to be divided into two to be scanned because of character limits. On the plus side, there is a history of scans performed.

Subscription plans start at $6.99/week (for 10,000 words).

According to the Check-Plagiarism website, documents are not saved or shared with third parties. There is a contact form but no live support.

• Text layout is kept intact in the online tool
• Difficult to read reports
• Performed poorly with academic sources
• Unclear data protection policy

Copyleaks performed relatively poorly with all source types. However, it was sometimes able to attribute an entire source block to the correct source.

The report distinguishes between text that is “identical” to a source, text that contains “minor changes,” and text that is “paraphrased.” However, its judgment is sometimes wrong.

The site report allows users to click part of the text and pull up the plagiarized source, but this is not possible in the downloadable report, which only lists all sources at the top. Additionally, in the report, 100 sources had been disabled. We had to enable them manually in order to have the report reflect a true plagiarism percentage.

The reports are difficult to read, as they use the same color highlights for all sources. Additionally, results are given sentence by sentence. To tell if an entire paragraph is plagiarized from the same source, you must click on each individual sentence.

Annual subscriptions start at $8.99/month (for 300,000 words).

Copyleaks claims that they “will never steal your work.” To permanently remove uploaded content from their database, though, users must contact customer support. The website has a chat option and a contact form.

• You can edit directly in the tool to, for example, exclude a source
• It is generally not able to identify full matches
• Report is very difficult to read

Small SEO Tools identified very few full matches, often marking sentences in the middle of an entirely plagiarized text as original material.

Additionally, when a scan was run a second time, the percentage of plagiarized material changed, indicating low reliability.

The PDF report is very difficult to read because all of the sources are marked in one color, and there are no clear links from the text to its source. The formatting of the original document is not preserved in the report.

Small SEO Tools plans start at $9.80/month for 40,000 words.

Small SEO Tools states that user files are immediately deleted once the scan has been run. They have a contact form on their website but do not offer other forms of support.

Quality of matches 

Plagiarism Detector was unable to find full matches, attributing individual sentences, rather than the entire section, to one or more sources. Overall, it found less than 40% of plagiarized content, and it performed particularly poorly with scholarly sources.

In the downloadable report, the format of the text is lost, making it hard to read. The list of sources is also difficult to cross-reference with the text above because the same colors are used for different sources.

Plagiarism Detector offers a rewrite tool to help resolve similarities, but the quality of this tool is questionable, and it does not help with the citation issues. You should resolve plagiarism by citing the relevant source, not by attempting to rewrite the text to disguise it.

Subscription plans start from $5/week (for 15,000 words).

Plagiarism Detector does not store or sell uploaded documents. There is no live support, but the website does offer a help request form.

Quetext detected about half the plagiarized text but was often unable to fully match the entire source text to one source. Instead, individual sentences were attributed to different sources.

The tool also sometimes attributed plagiarized material to an incorrect source.

Our testers found both the online report and the downloadable PDF almost impossible to work with. Both completely change the formatting of the text, making it difficult to tell what part of the paper plagiarized text comes from.

Additionally, sources are marked only in two colors (red for full plagiarism and orange for partial plagiarism), which makes it difficult to identify sources.

Plans start at $8.80/month.

Quetext does not store or re-upload your text, and it offers a help center with FAQs. There is no live support, but users can submit a help request on the website.

Smodin performed poorly in all rounds of testing. It was not able to find full matches, and in the heavily edited text, it found less than 10% of the plagiarized content. It often did not return even partial matches.

The tool has a very low limit of 12,000 characters (not words) per scan.

Both the online report and the downloadable PDF report are difficult to read. The downloadable report displays the uploaded document, but it doesn’t highlight the text that it flags as plagiarized. Instead, below this, it includes the individual parts of the text that it recognizes as plagiarism.

Plagiarism can be detected by your professor or readers if the tone, formatting, or style of your text is different in different parts of your paper, or if they’re familiar with the plagiarized source.

Many universities also use plagiarism detection software like Turnitin’s, which compares your text to a large database of other sources, flagging any similarities that come up.

It can be easier than you think to commit plagiarism by accident. Consider using a plagiarism checker prior to submitting your paper to ensure you haven’t missed any citations.

The accuracy depends on the plagiarism checker you use. Per our in-depth research , Scribbr is the most accurate plagiarism checker. Many free plagiarism checkers fail to detect all plagiarism or falsely flag text as plagiarism.

Plagiarism checkers work by using advanced database software to scan for matches between your text and existing texts. Their accuracy is determined by two factors: the algorithm (which recognizes the plagiarism) and the size of the database (with which your document is compared).

Yes, Scribbr offers a limited free version of its plagiarism checker in partnership with Turnitin. It uses Turnitin’s industry-leading plagiarism detection technology and has access to most content databases.

If you’re a university representative, you can contact the sales department of Turnitin .

Definition of Plagiarism

But before checking for plagiarism everyone should know, What Is Plagiarism?

“The act of pretension where you take one’s words and make them your own it can include ideas, thoughts, or any material that you can see/hear and make a copy of.”

If we talk in a legalistic manner then taking someone’s copyright and claiming it to be yours is unintentional plagiarism.

Self-Plagiarism

The concept of thinking that, self-plagiarism is only copying some other's paintings or borrowing someone else's unique idea. In my thoughts like "copying" and "borrowing" can cover the seriousness of the offense.

Scribbr’s Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker , namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases .

The add-on AI detector is powered by Scribbr’s proprietary software.

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2024.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker . This means you won’t be charged on a recurring basis – you only pay for what you use. We believe this provides you with the flexibility to use our service as frequently or infrequently as you need, without being tied to a contract or recurring fee structure.

You can find an overview of the prices per document here:

Please note that we can’t give refunds if you bought the plagiarism check thinking it was a subscription service as communication around this policy is clear throughout the order process.

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

• 99.3 billion current and historical webpages.
• 8 million publications from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell, and Taylor & Francis.

1. Unicheck

Our expert review:

Reasons to buy

Reasons to avoid.

Unicheck provides a high-quality service by combining high-end technology with smart design, and it clearly works – more than 1,000 academic institutions worldwide use this app.

This tool has access to more than 91 billion pages and library files, so you can be sure that it’s checking every source available for plagiarized material. And don’t worry about being overwhelmed with data once the app has searched the web, either: results appear in a straightforward interface that displays sources and color-codes copy, and each piece has a plagiarism score that’s adjusted as you edit the article.

Unicheck’s 99.9% system uptime means you’ll be able to check for plagiarism when you need it, and its authorized, encrypted accounts deliver high-level security for users.

The versatility and power continue elsewhere. A personal dashboard is perfect for managing loads of sources or articles, and Unicheck integrates with Office 365, Google Docs, and Chrome, so you can check for plagiarism without ever leaving those apps. It’s got an accessible API, too, so the tool integrates with other services.

Unicheck doesn’t have to be expensive, either.

No matter which one you choose, though, it’s clear that Unicheck remains one of the best plagiarism checkers on the market.

• ^ Back to the top

Scribbr provides a plagiarism checker that is part of a wider suite of tools that include an academic proofreading module and an APA reference generator. Unsurprisingly, the products on offer here will appeal to students and academics, and the site helps craft dissertations, essays, and thesis documents.

The plagiarism checker does a stellar job. Scribbr partners with Turnitin, which can detect everything from precise word and phrase matches to language where synonyms have been to used, and Scribbr checks writing against a database that covers 91 billion web pages and 69 million publications. Impressively, you can upload old assignments or referenced works to compare, too – perfect if you want to check your writing against something that won’t be in Scribbr’s database.

Beyond plagiarism, Scribbr offers expert editors who can edit essays, thesis documents, funding proposals, and literary reviews – it’s ideal for making sure that your academic work is top-notch, no matter the subject. Scribbr also provides a generator and checker for APA citations so you can be sure that no-one will question your sources.

Scibbr’s plagiarism checking service ranges in price from around $20 / £14 / AU$27  to $40 / £32 / AU$63, depending on the length of the document, and you’ll get your checked document within ten minutes.

The lack of dashboard and security features, when compared to other services, means that Scribbr isn’t suitable for large enterprises. But if you’re a student or academic, it’s well-designed and potentially invaluable.

3. Grammarly

Grammarly is one of the world’s most popular writing assistants, and no wonder: it does a fantastic job of checking written work for linguistic accuracy alongside its readability and tone. It’s also available as an app, as a plug-in for most word processing tools and as a browser extension.

It works in email clients , on social networks, and even in Slack and Discord too – so you’ll always be able to rely on this tool.

Grammarly has a great plagiarism checker, too. It uses the academic papers in ProQuest’s database and more than 16 billion web page sources to check for plagiarized text, and if the app detects copied language or phrases then you’ll get an alert in your document.

Grammarly’s plagiarism checker is free to use, but we don’t recommend this option – it will tell you if you’ve plagiarized, but it won’t show you where.

Instead, we recommend signing up to Grammarly’s paid tiers – you get its grammar, spelling, and punctuation tools alongside its clarity, engagement, tone, and plagiarism detection. Grammarly is one of the best linguistic tools on the web.

Grammarly’s prices start at around $11 / £10 / AU$16 per month.

4. PlagScan

PlagScan is a robust plagiarism deterrent focused on the academic circle. While used by many other fields as well, the features that make PlagScan stand apart among other plagiarism tools seem geared in this direction.

Pricing is pretty reasonable, with plans per word for individuals and some business plans as well. Prices can vary from $6 - $50 or more on average. On the higher level plans, there are advanced features including API abilities, support and more. There is also the ability to create more detailed reporting and integrate with tools you are already using.

Compared to other tools, PlagScan is pretty good about picking up possibilities, albeit sometimes too good. There are the occasional mistake, as in it notifies of a plagiarized item that is not actually there, however all around this tool is fairly accurate.

PlagScan itself even will say that the only true way to see if something is plagiarized is to utilize human support, confirming what PlagScan finds. But, without this tool, you would take much longer to find these similarities!

Lastly, there are easy color-coding highlights that help show what kind of infraction is found in offending pieces of writing.

Read our full PlagScan review .

5. Plagramme

Plagramme has a range of features that goes beyond what you’ll find with many other anti-plagiarism tools. It doesn’t just check billions of sources – it highlights your article with plagiarism risks, potentially paraphrased sections, poor citations, and textual similarities. Combine this with a straightforward scoring system, and you’ll be able to quickly see how much of any article is at risk.

This system is multilingual, so it can detect issues in different languages, and Plagramme also offers an authenticity service where its own editors check and fix documents manually. This does cost more, but it’s ideal if you have an important document that needs perfection. And, at the other end of the scale, there’s a free plagiarism checker – although this performs a quick check without the in-depth reporting or database access of the full product.

Once you’ve signed up for an account then you’ll be able to see Plagramme’s full range of services. It’ll cost a few dollars to skip the queue and a few more to get an in-depth report, and you can buy credits that work on any of Plagramme’s services.

This credit-based system and the emphasis on individual documents mean that Plagramme may not suit large organizations, but it’s well-suited to individuals and small businesses. 

Quetext has plagiarism detection algorithms that use a system called DeepSearch, which relies on word placement, deep learning, and contextual analysis to deliver smarter and more sensible results when you scan a document.

This tool can check for plagiarism in academic documents, news articles, blog posts, and webpages, so it’s versatile. It’s easy to use too: potentially plagiarized words or phrases are highlighted using a color-coded system with bolder shades for more significant issues. Side-by-side displays mean you can see exactly where the plagiarized text originated. And, at the end of the process, content gets a score so you can see how it’s performed.

Quetext also prizes itself on its straightforward pricing. If you pay for the basic package that allows you to check 100,000 words. The Plus package doubles the cost and increases the word allowance to 250,000, and there’s an Organization option that’s ideal for companies. Impressively, every product includes every feature – the good stuff is never held back for those who are willing to pay more.

Plagiarism checker FAQs

What is plagiarism.

Simply put, plagiarism is cheating. it refers to the act of copying one’s content and passing it off as your own. Grabbing someone’s photo and using it without permission and/or proper credits can be considered an act of plagiarism. Taking some text from a source and using it on your website without proper citation is also an act of plagiarism. 

In college, getting caught plagiarizing can lead to expulsion and can ultimately end any plans you have for your future. Stealing content for your own blog is not considered a form of flattery either, nor is it legal. Copying content for your own website can get you reported and your website taken down. 

What are the common types of plagiarism?

There are a couple of ways to commit plagiarism, but here are the five most common types:

1. Verbatim plagiarism - This is a common crime wherein a text or content is copied exactly as it is written without any form of credit or citation. 

2. Mosaic plagiarism - This type of plagiarism involves copying content from different websites or sources and combining them without any form of credit or citation. 

3. Global plagiarism - This means deliberately claiming someone else’s entire work as your own. 

4. Self plagiarism - This is when you resubmit your own work when you’ve already used it. It’s also known as auto plagiarism.

5. Accidental plagiarism - This occurs when you unintentionally commit plagiarism by paraphrasing a content and failing to cite or add credits. 

As content is a vital ingredient in SEO ranking which is always a neck to neck competition, websites are usually trying to come up with more content than they likely would have expected to be needing. A team of writers usually solve the problem, but it’s also where a new problem arises - monitoring the content.

Whether it’s an intentional copying of content or a missed citation, quote or credit, plagiarism isn’t as easy to detect if you’re dealing with tons of articles to check. The good news is that there are resources available - plagiarism checkers - that you can utilize to make it an easier task.

How to choose the best plagiarism checkers for you?

When choosing the best plagiarism checker for yourself, you'll want to start with assessing whether you want a standalone plagiarism checker or something with more features to improve writing. 

You'll want to consider the tool's user interface and learning curve. The simpler it is to operate, the more efficient you can be with your checking. 

If you're working alone, you may do well with a certain type of plagiarism checker, but the same tool may not be suitable for larger organizations. 

You'll also want to take the plagiarism tool's pricing into consideration, check how many users it can support, and analyze how well it integrates with third-party apps. 

How we test the best plagiarism checkers

To test the best plagiarism checkers, we first evaluated whether the tools are standalone plagiarism checkers or if they offer a suite of language improvement tools. 

We analyzed how large their content database is, whether there's citation checking, and what third-party apps they integrate with.

We assessed the tools' user interface and learning curve, and the kind of algorithm they were using to effectively spot plagiarism. We also considered their pricing plans, the number of users supported on each plan, and what type of client they'd be ideal for, among other things.

How you can avoid plagiarizing

Know the different types of plagiarism

There are several types of plagiarism, and it’s essential to understand the differences to avoid making these mistakes and prevent plagiarism in the classroom.

• Direct plagiarism: Using someone else’s exact words and using them as your own with no credit to the source. Eliminating portions of the text still qualifies as direct plagiarism.
• Patchwork plagiarism: Creating new text by combining exact phrases or sentences from multiple sources without acknowledging the original authors or sources.
• Self-plagiarism: Attempting to reuse or recycle your previous work and claiming it as a new piece of work without mentioning the source of original publication.
• Source-based plagiarism: Producing false sources within your writing or omitting one or more references from citations.

Cite your sources

Students often think of citations as a simple means of acknowledging another author's work. While this is their main purpose, there are other benefits as well.

Source citations also show readers where to go to learn more. By providing context around the citation in student papers, such as the source medium and when it was published, readers can locate the information more easily. Giving too little source information or improperly formatting it can result in unintentional plagiarism. These mistakes also make it difficult for readers to locate the original source and verify information.

Quetext's citation generator makes it easy for students to accurately cite their sources without slowing down their writing process. Once a user inputs the text, the software identifies the passages that require a citation and subsequently generates it in the style required — APA, MLA, or Chicago.

Always use a plagiarism checker

The best way to avoid severe plagiarism consequences is to use a plagiarism checker. Often, plagiarism is unintentional and results from poor paraphrasing of material found online. Using a plagiarism checker, the student can avoid accusations of any kind of plagiarism and benefit from a close review of the original material.

Quetext's plagiarism checker provides a speedy, easy process for students to receive accurate results, identifying areas of concern and providing on-page solutions.

Plagiarism Checker for Students FAQ

What are the consequences if a student is caught plagiarizing.

The consequences of plagiarism vary according to the student’s academic institution and grade level. For example, a middle school student who plagiarizes within an essay may receive a stern warning and additional instruction related to the process of citing sources or summarizing one’s thoughts.

However, students in higher education institutions guilty of plagiarism in academic papers face much steeper repercussions, including, but not limited, to failing grades and disciplinary or legal action. Factors such as the assignment itself, the instructor, and whether or not it is your first offense impact the outcome.

Depending on the severity of the situation, plagiarism can also impact a student’s reputation or future career opportunities.

How does a plagiarism checker help students?

A plagiarism checker helps students be proactive in finding instances of plagiarism before an assignment is completed and turned in with no way to correct the errors.

In addition, by identifying the potential conflicts early, students can conduct further research to find alternative sources to understand the material better and revise or rewrite the offending passages.

Plagiarism checkers also help students learn innovative writing techniques, improve their writing skills through better research and experience in summarizing ideas, and preserve academic integrity.

Do teachers use plagiarism checkers?

Many teachers use plagiarism checkers to ensure a student’s submission is 100% original work. With the rise of easy-to-use tools like Quetext, checking for authenticity and text matches is a quick and affordable process to scan millions of online data sources.

Using plagiarism checkers also allows teachers to educate their students on the importance of citing sources and the ethical responsibilities of research and opinion writing.

Plagiarism has always been a source of concern for teachers, but until now, options for manual detection have limited their opportunities to identify the problem efficiently. However, the evolution of technology in this area has made the tools more accessible than ever.

How do teachers check a paper for plagiarism?

Teachers are skilled at detecting plagiarism, especially those who have been teaching for a significant period or who teach in the areas of English or Literature. Some teachers use a simple technique of entering a sentence into a search engine to find instances of duplicate text on web pages.

However, this manner of plagiarism detection is manually intensive and dependent upon unreliable algorithms. Some may use their writer’s intuition by identifying anomalies in sentence structure, inconsistencies in vocabulary or grammar, or a combination of all of these.

Others use more sophisticated and robust plagiarism detection software, like Quetext. Quetext can scour millions of sites using DeepSearch™ technology to identify plagiarism in seconds. These tools also enable instructors to work with students to improve their writing and avoid repeating the same mistakes in the future.

Can students get in trouble for accidental plagiarism?

Yes, students can be penalized for plagiarism, even if it was an accident. Unfortunately, instructors have no way of knowing the intent behind plagiarism. Depending on the type of plagiarism, instructors may allow leeway for students to learn from their mistakes and correct the work without the threat of severe consequences.

However, repeat offenders are less likely to receive this flexibility and may face steeper penalties. Additionally, instructors of college-level courses with clear plagiarism guidelines and policies may be less inclined to let students off the hook and instead enforce severe consequences.

Is there a free plagiarism checker for students?

Yes! Quetext offers both a free and a paid subscription for students to seamlessly verify their writing. Quetext goes beyond traditional plagiarism checkers to provide students with advanced technology that puts content through three layers of evaluation in just a matter of seconds. This level of insight enables students to understand the degree to which the text has been plagiarized and decide whether to rewrite the text or use the citation assistant to cite sources.

Quetext also offers a detailed report students can use to document their editing efforts and present as proof of a plagiarism-free, 100% original content document.

Quetext's plagiarism tool also offers flexible pricing for its Pro features which facilitates the citation of online sources, attributions, and real-time feedback for writing improvement.

How can a student check for plagiarism?

Anyone can enter the text from a research paper into a search engine and find potential matches that identify instances of plagiarized content or duplicate content. However, this method is largely ineffective and does not identify every area of concern.

Students can use Quetext's free online plagiarism checker by creating an account, copying and pasting the text in question into the plagiarism checker, and receiving a comprehensive analysis with color-coded feedback, a plagiarism percentage score, and options for editing the text.

Quetext is one of the best plagiarism checkers available with high-quality insights and accurate results.

Do you have any questions, how long does the plagiarism detector online take.

The plagiarism detector online, working on a bachelor’s or master’s thesis (60-80 pages), normally takes between 10 and 20 minutes. It depends on the number of words submitted. In the case of longer pieces of work (200-300 pages), the plagiarism detector can take up to an hour.

Does the plagiarism detector online work in other languages?

Yes! The plagiarism detector online works in all languages. Regardless of the language or if you’re writing a Master’s thesis or an essay, the plagiarism detector online will work for you.

Will the document I upload be saved to a database?

Do I have to register for the plagiarism detector online first?

No! You can just upload your document, choose your payment method, and then use the plagiarism detector online without a user account or registering. It’s quick and easy, plus, none of your data will be saved once the check is completed. Start your plagiarism check right away!

Which sources will be used by the plagiarism detector online?

All publicly accessible online sources will be used in plagiarism detector online. This includes publicly accessible websites, books, reports, journals, etc. Databases where payment is required are excluded. If you’re having trouble organizing and referencing your sources properly, head over to our blog. We have many articles about proper citation and referencing .

Will books also be referred to in the plagiarism test tool?

If the book is online in a publicly accessible database, then the plagiarism test tool will also find this source. However, if you have cited a hard copy of a book, and it also exists online, then this may be picked up by the plagiarism test tool. If you have cited the source, you have no need to worry- it’s simply an extra precaution. Take a look at our blog post for more information about citing books.

What’s the difference between the BachelorPrint plagiarism test tool and Turnitin?

The BachelorPrint plagiarism test tool doesn’t save any uploaded work for data protection reasons, unlike Turnitin. Accordingly, we don’t rely on the same database as Turnitin. However, our plagiarism detector searches billions of publicly available sources on the World Wide Web.

Information: If the work is scanned for plagiarism in advance with Turnitin, and the university also uses Turnitin, there is a considerable potential risk for the writer. As Turnitin saves the uploaded work, this will then be in their database. If the university scans the same work on it, it will then be classified as complete plagiarism. This has already occurred a few times. The student’s work failed in the first instance, and they had to prove that they had written the document saved by Turnitin.

I haven't received an email with the plagiarism test tool. What should I do?

The email might have gone into your spam folder. In really rare cases, our email with the plagiarism report from the plagiarism test tool might have been blocked by your email provider and hasn’t been received. Please contact us at [email protected] . We will email you the plagiarism report again.

Too few pages are shown in the plagiarism report. Why?

For an overview, only text passages that might contain plagiarism are shown in the plagiarism report. The other pages where no plagiarism is suspected will not be shown. So fewer pages in your plagiarism report is really a good sign- it means that you’ve cited your sources correctly. Take a look at our blog article for more information about referencing and citation styles.

Why is a section marked as suspected plagiarism even though I have cited the source?

It’s possible that a section of text is marked as suspected plagiarism even though it has already been correctly cited, for example from a book. This happens if the test tool finds a further online source. In this case, the suspected plagiarism can be ignored and serves as extra peace of mind.
