After thorough research, I pulled the 5 best paraphrasing tools for academic writing that will even trick Turnitin, our biggest enemy.

Okay, maybe that was harsh. 

However, Turnitin, a plagiarism detector that promotes academic integrity, can be tricked using these 5 tools.

Keep reading below if you are ready to finally find a solution for painful academic writing tasks.

Best Paraphrasing Tools for Academic Writing

• Spin Rewriter
• SpinnerChief

My Top Pick Up-Front

Without wasting your time, my top pick up-front is QuillBot .

QuillBot is my top pick since it is:

• most affordable
• most versatile
• almost always passes Turnitin plagiarism checker
• most accurate
• straightforward to use

Who is this article for?

This article is for students who are not linguistic experts and seek to avoid common errors and stress and save time while writing thesis and research papers.

Keep reading below if you want to:

• save time while researching
• write better literature reviews
• paraphrase thesis
• write hour-long content within seconds
• avoid paraphrasing manually
• trick Turnitin and professors

The Best Paraphrasing Tools for Academic Writing (Review)

Without further ado, let’s learn the pros and cons of each paraphrasing tool.

1. QuillBot – Best Overall

QuillBot is a writing and paraphrasing tool that leverages modern A.I. technology. 

Nevertheless, the most important feature for you is the paraphrasing tool that uses complex rewording mechanisms to pass plagiarism checkers and save you time. 

Here is an example of QuillBot rewriting one of the sections from a random law research paper:

When you click on “Rephrase” in the right window where the text is being reworded, you can choose the style of rewriting . It is also called a rewriting mode, and you can see that below:

In this instance, I choose the formal rewriting mode since it suits our need to rewrite complex research papers and theses.

You can play around and also manually rewrite certain parts of the text. QuillBot will even give you suggestions and synonyms to include in your text. 

Furthermore, you can also see some other features like:

• Grammar Checker
• Citation Generator

The second most crucial QuillBot feature for you is Summarizer. QuillBot Summarizer goes through stacks of reading material and identifies key findings and points. Imagine having a virtual research assistant who helps you do all the necessary work before starting to write. 

You can combine the two tools to create the best document on a particular topic. Use Summarizer to learn the whole document faster by only remembering key points and findings. In addition, use a rephrasing tool to avoid plagiarism detection and save time.

The only downside of Quillbot is its Chrome Extension doesn’t correct errors automatically. You must paste the sentences into the main site to do the paraphrasing.

QuillBot Pricing

Free QuillBot account can only process up to 700 characters at a time. That’s why you need a premium version to paraphrase up to 10000 characters. 

The Premium QuillBot version will save you more time.

Monthly Plan: $7.95 every month

Semi-Annual Plan: $29.50 every 6 months

Annual Plan: $39.95 every year

• passes Turnitin
• easy to use
• limited free version
• Chrome Extension limitations

2. Spinbot – Best Free Version

I believe Spinbot is the best alternative to QuillBot since it offers features like text rewriters, article spinning, and a content-creating tool. Spinbot provides the best free version since it lets you paraphrase 10000 characters. 

In this sense, Spinbot offers the best features for a free version of the software compared to the rest of the paraphrasing tools. It spins the words and paraphrases the whole text in seconds. You even have the option to ignore specific words or capitalized letters to further boost the authenticity of the text. 

In addition, Spinbot requires no registration. 

Here is an example of Spinbot’s free paraphrasing tool. I used the exact text as before:

Some of the downsides of the tool are the lack of extensions which can make your rewriting and research process a lot harder. Even though the free version lets you paraphrase up to 10000 characters, ads and CAPTCHA code can still be annoying from time to time. There is always an option to purchase a premium version. 

Let’s see what it has to offer:

Spinbot Pricing

The Premium Spinbot version gets rid of boring CAPTCHA and disturbing ads. In fact, that is the only advantage of a premium account, so make sure to check if that is going to make your life easier.

Monthly Plan: $10 every month

Semi-Annual Plan: $50 every 6 months

Annual Plan: $75 every year

• best QuillBot alternative
• offers the best free version
• paraphrasing up to 10000 characters for free
• customizable options to suit your needs
• the free version has ads and a CAPTCHA code

3. WordAi – Best to Avoid Plagiarism Detection

WordAi is another paraphrasing tool that leverages artificial intelligence and works very fast. However, there are better features of this tool than those. 

WordAi is the only tool that passes any plagiarism detector, including our famous Turnitin, as 100% authentic. It instantly rewrites your thesis and research works. Also, you can upload 1000 articles and spin them all simultaneously. 

Another cool feature this tool has is the ability to intelligently spin text titles. It is almost impossible to spot the rewriting and spinning that take place. 

The only downside of this A.I. paraphrasing tool is that it’s only free for three days. Also, to use the tool for three days for free, you need to create an account. In the end, you must purchase the premium plan. 

WordAi also has the option to integrate with Anti Forge. Still, we won’t get deep into that since you, as a student, will probably provide some offline resources for paraphrasing. 

However, this integration can be helpful if you are sourcing content for your thesis from the internet.

WordAi Pricing

Here are two options WordAi offers for the premium version:

Monthly Plan : $49.95 per month

Yearly Plan : $347 per year

• 100% authentic text (passes every plagiarism detector)
• upload up to 1000 works and spin them all at the same time
• text titles spinning
• integrates with other similar tools, such as Anti Forge
• only free for three days

4. Spin Rewriter – Best for All Devices

Spin Rewriter is another popular paraphrasing tool initially developed to aid SEO specialists. An SEO specialist is a person who performs search engine optimization. This is important because SEO has become much more about semantics and meaning today. 

So, how does this feature benefit you? 

Simply put, Spin Rewriter is one of the few tools close to understanding the meaning behind the text(semantics). Your paraphrased text will be more accurate, and the original text’s meaning will be much more visible and accessible to the reader, your professor. 

However, there are other benefits of using this tool. 

Spin Rewriter is cloud-based, meaning you can use it on devices such as:

• mobile phones

Basically, on every device, you can think of. Okay, that was an exaggeration. Smartwatches are still to be included. 

Furthermore, you can get more than 1000 variations of a single text. This is known as mass export. However, you can also rewrite and paraphrase multiple articles multiple times. The meaning of the text is always going to stay.

Spin Rewriter Pricing

Here comes the only downside of this tool. 

There is no free version, and you can only have a free 5-day trial for the yearly Plan. Maybe not the best option budget-wise, but still something to think about. 

Monthly Plan : $47 per month

Yearly Plan : $77 per year

Lifetime Plan : $497 per year

• preserves meaning
• compatible with all devices
• up to 1000 variations of a single text
• no free version
• only a 5-day free trial

5. SpinnerChief – Most Accurate Synonym Use

SpinnerChief is highly recommended for a thesis paraphrasing for team collaborations. It leverages artificial intelligence to generate the most unique content that aims to pass any plagiarism detector. 

Their newly-added technologies, such as statistical replacement and part-of-speech analysis, ensure the most appropriate use of synonyms. Also, the number of words continues to expand, and new synonyms are constantly added as people continue using their software. 

Furthermore, you can use SpinnerChief to:

• spin thousands of works in a short period
• manually paraphrase text or customize rules to suit your needs
• paraphrase content in different languages such as French, Spanish, German, Indonesian, etc.(translation API like Bing API is required)

SpinnerChief is not only web-based and has both mobile and desktop versions. Moreover, it supports Mac, Windows, Android, and iOS. 

SpinnerChief Pricing

One of this tool’s downsides is the price of a premium version. However, you can still use a free version with some basic features.

Elite Version : $197 one-time fee

Ultimate Version : $107 per year ($307 one-time fee)

Team Version : $277 per year ($627 one-time fee)

• good for teams
• accurate synonym use
• customizable rewording rules
• compatible with multiple languages
• supports Mac, Windows, iOS, and Android
• the free version only has basic features

More Paraphrasing Tools 

Here are two tools that didn’t make our top 5 list but are still worth mentioning.

Clever Spinner

Clever Spinner is an article rewriter tool that is a little outdated by today’s standards. It only offers a 3-day trial but has Copyscape and API integration. Also, it rewrites articles in about 10 seconds, but as we mentioned before, that is below today’s standards. 

Some tools on our list rewrite the whole article immediately and are much more accurate than Clever Spinner. The quality of content could be better, and too many unnecessary options don’t do anything to make the text more authentic. 

Also, the software lacks customer support, and if you are stuck with some of its features, you are left to fix the problem on your own.

Ref-n-write

I didn’t put this tool on the list because it needs to be updated. If you visit their site, you can see that it looks outdated. Strangely enough, it ranks on the first page when you type the query “best paraphrasing tool for academic writing.” 

Reviews are generally mixed, and some people are unsatisfied with their rewriting tool. The positive thing about this tool is it’s compatible with Mac and Windows computers. I am leaving this one to you to decide.

Paraphrasing Tools F.A.Q.

Now, let’s address some most common questions regarding paraphrasing tools.

Can Turnitin detect QuillBot?

Turnitin can’t detect QuillBot because it uses algorithms that don’t necessarily detect paraphrasing. Turnitin usually finds similar phrases, grammatical patterns, and sentence structures. Therefore, QuillBot’s paraphrased content is unique enough to pass Turnitin’s detection.

Is QuillBot allowed in University?

There are specific penalties if University detects the use of softwares like Quillbot and SpinBot. However, the point is most Universities rarely notice such paraphrased texts.

When paraphrasing what should you avoid?

You must always avoid just changing a few words in a single sentence and leaving it as it is. Seek to always use your own words to convey the same(author’s) meaning.

Can you paraphrase without citing?

In theory, paraphrasing always requires you to use a citation. This is because stealing ideas is forbidden since they belong to someone else. A wise psychologist once said:  People don’t own ideas, but ideas own people. 

Why do we paraphrase in academic writing?

Paraphrasing is one of the most essential skills to learn since it demonstrates your ability to understand the source well enough to articulate it in your own words.

How do you summarize without plagiarizing?

Always follow these rules to avoid plagiarism when summarizing an article: 1. Write only in your own words. 2. Cite the source with an in-text citation

Let’s sum it up!

Finding the right paraphrasing tool for academic writing can take time and effort. 

Factors like budget, level of uniqueness, and quantity of work must be considered.

I hope that after reading this article, you clearly understand which tool for academic writing is the best for you.

Let me know in the comments below which tool you liked the most and why.

☝️ Paraphrasing as the Best Tool against Plagiarism

As you know, plagiarism is a form of academic dishonesty. You can’t take someone’s ideas and pass them off as your own.

Plagiarism can have severe consequences. If you run a website or a blog and copy and paste articles from other sources without changes, search engines will lower your website’s score. This means that you will have fewer visitors and, as a result, fewer earnings (if you run an online store, provide services, or monetize your website in other ways).

In the business world, plagiarism can also have negative consequences. Copyright violations, for example, can result in million-dollar lawsuits, or in a loss of trust among customers, etc.

Below, you will find the most common types of plagiarism. Familiarize yourself so you can avoid them.

8 Types of Plagiarism

These are eight types of plagiarism that are often seen in academic writing:

• Cloning or identical copying. This occurs when someone copies another’s text word for word and claims it as their own.
• Mixture. This type of plagiarism occurs when you gather information from different sources and put it together, claiming it as your own paper.
• Copy-Paste. This type of plagiarism is seen in papers where the author has copied and pasted significant parts of their paper from one source without changes.
• Misleading attribution. This occurs when someone uses a citation without giving credit to a primary source.
• Self-plagiarism. This happens when you decide to reuse your old papers without proper citation and credits. Yes, you have to cite your own writing if you use it again!

Regardless of its type, plagiarism has serious consequences. A student who is caught plagiarizing can be expelled from college or university.

📝 Anti-plagiarism Tools & Techniques

Avoiding plagiarism is easy. Keep reading to find out more:

Quoting and Quotes

A quote is a copy of an original source that is properly credited. Depending on the formatting style, there are different style rules.

Here are three of the most popular formatting style requirements:

The first thing that you need to determine when quoting in APA is the length of the quote. If it is less than 40 words, you need to add a phrase that contains the author’s name and the publication date in parentheses:

Darwin (1857) stated, “A scientific man ought to have no wishes, no affections, - a mere heart of stone.”

If you don’t name the author before the quote, you must put their name, publication date and page number (if applicable) in parenthesis after the quote:

He said, “A scientific man ought to have no wishes, no affections, - a mere heart of stone” (Darwin, 1857).

If the quote exceeds 40 words, the quote must be placed in a separate block within the text and put in quotation marks.

Rules for quoting in MLA are similar to APA. If the quote is fewer than four lines, you must denote it with double quotation marks. You should provide information about the author and page number in your in-text citation and provide complete information on the reference page.

If you want to use a quote in the Chicago style, you must use footnotes and endnotes to provide information about the source. A superscript number should be placed after the quote:

Darwin stated that “A scientific man ought to have no wishes, no affections, - a mere heart of stone”. 1

If you’re going to quote 100 words, or more than five lines of a text, you need to write it as a separate block without quotation marks.

Paraphrasing

Another way to avoid plagiarism in your writing is to paraphrase the source. When paraphrasing, you must avoid copying more than two words in a row. In other cases, you should use quotation marks.

Check out how to paraphrase in APA, MLA, and Chicago styles below:

When you paraphrase in APA, you must provide the author’s last name and the date of publication in your paper. It is not necessary to include the page number in the citation.

(Darwin, 1857)

In MLA, you need to include the page number after the author’s last name. You should avoid using a comma between them. You should also paraphrase, but not misconstrue the author’s meaning.

(Darwin 191)

Similar to quotes, when you paraphrase in Chicago style, you should use a superscript number after the in-text citation:

Darwin stated that scientists should be stone-like and avoid desires or feelings. 1

Revising from turnitin: strategies for paraphrase.

To paraphrase is to experience a tension: you must accurately reproduce your source’s ideas, but you must do so in your own language. The convention in many disciplines—mostly in the sciences and social sciences—is for writers to paraphrase a source’s ideas in their own language rather than relying on quotation. But even in disciplines where quoting is common, paraphrase is an important and widely-used approach to engaging with sources.

How much do you need to change a source’s words for the language to be your own? You may have heard that five words in a row is considered plagiarism. We would like to give you that kind of clear-cut standard for judging when you have plagiarized. But plagiarism is more a matter of context than of a specific number of words. Reproducing a long string of generic words would not be considered plagiarism, while copying a single word—if used for the first time, or in a novel way by a source—could be.

If Turnitin flags a passage in your paper as similar to a passage in one of your sources, you’ll need to consider whether you are using the source’s language fairly. Look for words and phrasings that the source author could plausibly claim as their own. If those phrasings appear in the same form in your writing, you’ll need to rephrase them to avoid the impression that you are claiming credit for another scholar’s work.

Paraphrasing fairly can be a challenge, especially when the language of your source is highly technical, when the subject is specific, or when the author has conveyed an idea with exceptional clarity. Working with the kinds of results you might find on a Turnitin originality report, the pages linked below offer a variety of strategies for paraphrasing a source’s language fairly and accurately.

Strategy 1: Set the Source Aside

Strategy 2: condense the source’s language, strategy 3: replace jargon with more common vocabulary, strategy 4: adapt the source’s language to the goals of your argument, strategy 5: revise the structure of the source’s sentences, you may be interested in.

It depends on the writer’s intent, the specific rules of your class and instructor, and your definition of cheating. If you use a tool to aid you in writing an essay but aren’t able to properly credit the sources that you used, then you’re most likely cheating.  

But if you use a paraphrasing tool as a reference tool and make sure that you are using proper grammar and terminology, then it’s probably not cheating.

Can Turnitin Detect Paraphrasing? (Pros & Cons, Methods)

Imagine this scenario: You’ve spent hours researching and writing an essay, but you’re concerned about unintentionally plagiarizing someone else’s work.

You may have heard of Turnitin, a widely used plagiarism detection tool , and wonder if it can detect paraphrasing.

Yes, Turnitin can detect paraphrasing to some extent. It compares submitted texts against a vast database and analyzes similarities in wording, phrasing, and sentence structure. It can identify both direct and hidden paraphrasing techniques. However, it has limitations and may not catch every instance of paraphrasing, especially if the rephrasing is extensive or non-academic sources are used.

In this article, we will delve into Turnitin’s functionality, its ability to detect paraphrasing and explore the pros and cons of using this tool.

Additionally, we will provide alternative solutions to help you navigate the realm of academic integrity effectively.

Turnitin Plans and Pricing

The table below is a summary of the plans and pricing of Turnitin, along with the recommended users for each plan:

Note: The pricing for Turnitin plans varies depending on factors such as the educational institution, organization, or licensing agreements.

How Does Turnitin Work?

Turnitin is a powerful tool used by educational institutions to identify instances of plagiarism.

It works by comparing submitted texts against a vast database of academic sources, previously submitted papers, and internet content.

Turnitin primarily focuses on detecting similarities in wording, phrasing, and sentence structure to determine potential instances of plagiarism.

How Turnitin Identifies Direct Paraphrasing:

Turnitin has the capability to detect direct paraphrasing, where words are substituted or sentence structure is rearranged without adding original ideas.

The tool’s algorithms can identify similarities in sentence structure, wording, and grammar patterns, which are indicative of potential paraphrasing.

For instance, if two papers contain identical sentences with only a few words changed, Turnitin will flag them as potential instances of direct paraphrasing.

Detecting Hidden Paraphrasing Techniques:

Turnitin’s algorithms are designed to detect more sophisticated paraphrasing techniques as well.

These techniques involve using synonyms or rephrasing sentences while maintaining the original meaning.

The tool can identify patterns in the usage of synonyms or detect similarities in sentence structures, even if the wording is different.

For example, if a sentence is rephrased but retains the same structure and ideas, Turnitin can still flag it as paraphrasing.

Limitations of Turnitin in Detecting Paraphrasing:

Despite its effectiveness, Turnitin has certain limitations in detecting paraphrasing.

Subtle paraphrasing techniques that involve extensive rephrasing or the use of non-academic sources may go undetected by the tool.

This is because Turnitin’s focus is primarily on textual similarities rather than analyzing the underlying concepts or ideas. Hence, it is crucial to understand that Turnitin may not catch every instance of paraphrasing.

Tips for Effective Paraphrasing:

To avoid plagiarism and detection by Turnitin, here are some tips for effective paraphrasing:

• Understand the original content: Gain a thorough understanding of the source material before attempting to paraphrase.
• Change sentence structure: Rearrange sentences and alter their structure to present ideas in a fresh manner.
• Use different words and synonyms: Replace words and phrases with suitable synonyms to convey the same meaning.
• Add personal insights: Inject your own thoughts and insights into the paraphrased content to demonstrate originality.

Alternative Tools for Detecting Paraphrasing:

While Turnitin is widely used, there are alternative tools available that specialize in identifying paraphrasing.

For example, Unicheck and Grammarly offer comprehensive plagiarism detection features.

Unicheck utilizes machine learning algorithms to identify paraphrasing techniques effectively, while Grammarly provides real-time suggestions for avoiding plagiarism and improving writing quality.

Exploring these alternatives can provide additional support in maintaining academic integrity.

How Turnitin Compares To Originality.ai, Grammarly Business, and ProWritingAid

Note: Checkmarks indicate the presence of the respective feature, while “❌” indicates the absence of the feature.

Turnitin is a powerful tool for plagiarism and paraphrasing detection, but it lacks grammar and spelling checking as well as real-time suggestions for writing style.

Originality.ai and ProWritingAid offer comprehensive checks for plagiarism, paraphrasing, grammar, spelling, writing style suggestions, and real-time feedback.

Grammarly Business offers a combination of grammar, spelling, and writing style suggestions but lacks plagiarism and paraphrasing detection.

All four tools support various document formats, multiple languages, and integrations.

Pricing for each tool is subscription-based. Consider your specific needs to determine which tool best suits your requirements.

Academic Policies and Consequences:

Academic institutions have strict policies regarding plagiarism, and the consequences can be severe.

Plagiarism undermines the principles of integrity and academic honesty.

Penalties for submitting paraphrased content detected by Turnitin can range from receiving a failing grade to academic probation or even expulsion.

It’s vital to prioritize originality and cite sources properly to avoid these repercussions.

Educational Approaches to Paraphrasing:

Recognizing the significance of proper paraphrasing, educational institutions actively promote effective techniques to students.

Educators play a crucial role in teaching students how to paraphrase ethically and avoid plagiarism.

Writing centers, online guides, and workshops are valuable resources that offer assistance in paraphrasing and reinforce the importance of original work.

Pros and Cons of Using Turnitin for Paraphrasing Detection:

Should students paraphrase.

Yes, students should practice paraphrasing under certain circumstances.

Paraphrasing is an essential skill that demonstrates comprehension, critical thinking, and the ability to express ideas in one’s own words.

Here are some circumstances in which paraphrasing is appropriate and encouraged:

• Clarifying complex ideas: Paraphrasing allows students to simplify and restate complex concepts in a more understandable manner. This is especially helpful when explaining difficult topics or breaking down technical information.
• Incorporating sources in academic writing: When conducting research or writing academic papers, students should paraphrase to integrate information from various sources. Paraphrasing helps avoid excessive direct quotations and allows students to present the ideas and arguments of others in their own writing style.
• Demonstrating originality: Paraphrasing is a way for students to showcase their own interpretation and analysis of a topic. By paraphrasing, students can add their insights, perspectives, and critical thinking to the information they gather from different sources.
• Avoiding plagiarism: Paraphrasing is an effective way to avoid unintentional plagiarism. By rephrasing ideas in their own words, students can properly attribute sources while demonstrating their understanding of the material.

It’s important to note that paraphrasing should always be accompanied by proper citation and referencing.

Students should acknowledge the original source whenever they paraphrase or use ideas from external material.

Additionally, paraphrasing should be done in a way that maintains the accuracy and integrity of the original information.

Turnitin is a valuable tool for identifying instances of paraphrasing in academic work.

It can detect both direct and hidden paraphrasing techniques. However, it is essential to recognize its limitations and understand that Turnitin may not catch every instance of paraphrasing.

When you employ effective paraphrasing techniques, utilize alternative tools, and adhere to academic policies, as a student, you can maintain your academic integrity while producing original and well-cited work.

Remember, the goal is not just to avoid detection but to foster a culture of ethical writing and critical thinking.

Metrics details

The application of artificial intelligence (AI) in academic writing has raised concerns regarding accuracy, ethics, and scientific rigour. Some AI content detectors may not accurately identify AI-generated texts, especially those that have undergone paraphrasing. Therefore, there is a pressing need for efficacious approaches or guidelines to govern AI usage in specific disciplines.

Our study aims to compare the accuracy of mainstream AI content detectors and human reviewers in detecting AI-generated rehabilitation-related articles with or without paraphrasing.

Study design

This cross-sectional study purposively chose 50 rehabilitation-related articles from four peer-reviewed journals, and then fabricated another 50 articles using ChatGPT. Specifically, ChatGPT was used to generate the introduction, discussion, and conclusion sections based on the original titles, methods, and results. Wordtune was then used to rephrase the ChatGPT-generated articles. Six common AI content detectors (Originality.ai, Turnitin, ZeroGPT, GPTZero, Content at Scale, and GPT-2 Output Detector) were employed to identify AI content for the original, ChatGPT-generated and AI-rephrased articles. Four human reviewers (two student reviewers and two professorial reviewers) were recruited to differentiate between the original articles and AI-rephrased articles, which were expected to be more difficult to detect. They were instructed to give reasons for their judgements.

Originality.ai correctly detected 100% of ChatGPT-generated and AI-rephrased texts. ZeroGPT accurately detected 96% of ChatGPT-generated and 88% of AI-rephrased articles. The areas under the receiver operating characteristic curve (AUROC) of ZeroGPT were 0.98 for identifying human-written and AI articles. Turnitin showed a 0% misclassification rate for human-written articles, although it only identified 30% of AI-rephrased articles. Professorial reviewers accurately discriminated at least 96% of AI-rephrased articles, but they misclassified 12% of human-written articles as AI-generated. On average, students only identified 76% of AI-rephrased articles. Reviewers identified AI-rephrased articles based on ‘incoherent content’ (34.36%), followed by ‘grammatical errors’ (20.26%), and ‘insufficient evidence’ (16.15%).

Conclusions and relevance

This study directly compared the accuracy of advanced AI detectors and human reviewers in detecting AI-generated medical writing after paraphrasing. Our findings demonstrate that specific detectors and experienced reviewers can accurately identify articles generated by Large Language Models, even after paraphrasing. The rationale employed by our reviewers in their assessments can inform future evaluation strategies for monitoring AI usage in medical education or publications. AI content detectors may be incorporated as an additional screening tool in the peer-review process of academic journals.

Introduction

Chat Generative Pre-trained Transformer (ChatGPT; OpenAI, USA) is a popular and responsive chatbot that has surpassed other Large Language Models (LLMs) in terms of usage (ChatGPT Statistics 2023 ). Being trained with 175 billion parameters, ChatGPT has demonstrated its capabilities in the field of medicine and digital health (OpenAI 2023 ). It has been reported to be able to solve higher-order reasoning questions in pathology (Sinha 2023 ). Currently, ChatGPT has been used in generating discharge summaries (Patel &Lam 2023 ), aiding in diagnosis (Mehnen et al. 2023 ), and providing health information to patients with cancer (Hopkins et al. 2023 ). Currently, ChatGPT has become a valuable writing assistant, especially in medical writing (Imran & Almusharaf 2023 ).

However, scientists did not support granting ChatGPT authorship in academic publishing because it could not be held accountable for the ethics of the content (Stokel-Walker 2023 ). Its tendency to generate plausible but non-rigorous or misleading content has raised doubts about the reliability of its outputs (Sallam 2023 ; Manohar & Prasad 2023 ). This poses a risk of disseminating unsubstantiated information. Therefore, scholars have been exploring ways to detect AI-generated content to uphold academic integrity, although there are conflicting perspectives on the utilization of detectors in academic publishing. Previous research found that 14 existing AI detection tools exhibited an average accuracy of less than 80% (Weber-Wulff et al. 2023 ). However, the availability of paraphrasing tools further complicates the detection of LLM-generated texts. Some AI content detectors were ineffective in identifying paraphrased texts (Anderson et al. 2023 ; Weber-Wulff et al. 2023 ). Moreover, some detectors may misclassify human-written articles, which can undermine the credibility of academic publications (Liang et al. 2023 ; Sadasivan et al. 2023 ).

Nevertheless, there have been advancements in AI content detectors. Turnitin and Originality.ai have shown excellent accuracy in discriminating between AI-generated and human-written essays in various academic disciplines (e.g., social sciences, natural sciences, and humanities) (Walters 2023 ). However, their effectiveness in detecting paraphrased academic articles remains uncertain. Importantly, the accuracy of universal AI detectors has shown inconsistencies across studies in different domains (Gao et al. 2023 ; Anderson et al. 2023 ; Walters 2023 ). Therefore, continuous efforts are necessary to identify detectors that can achieve near-perfect accuracy, especially in the detection of medical texts, which is of particular concern to the academic community.

In addition to using AI detectors to help identify AI-generated articles, it is crucial to assess the ability of human reviewers to detect AI-generated formal academic articles. A study found that four peer reviewers only achieved an average accuracy of 68% in identifying ChatGPT-generated biomedical abstracts (Gao et al. 2023 ). However, this study had limitations because the reviewers only assessed abstracts instead of full-text articles, and their assessments were limited to a binary choice of ‘yes’ or ‘no’ without providing any justifications for their decisions. The reported moderate accuracy is inadequate for informing new editorial policy regarding AI usage. To establish effective regulations for supervising AI usage in journal publishing, it is necessary to continuously explore the accuracy of experienced human reviewers and to understand the patterns and stylistic features of AI-generated content. This can help researchers, educators, and editors develop discipline-specific guidelines to effectively supervise AI usage in academic publishing.

Against this background, the current study aimed to (1) compare the accuracy of several common AI content detectors and human reviewers with different levels of research training in detecting AI-generated academic articles with or without paraphrasing; and (2) understand the rationale by human reviewers for determining AI-generated content.

The current study was approved by the Institutional Review Board of a university. This study consisted of four stages: (1) identifying 50 published peer-reviewed papers from four high-impact journals; (2) generating artificial papers using ChatGPT; (3) rephrasing the ChatGPT-generated papers using a paraphrasing tool called Wordtune; and (4) employing six AI content detectors to distinguish between the original papers, ChatGPT-generated papers, and AI-rephrased papers. To determine human reviewers’ ability to discern between the original papers and AI-rephrased papers, four reviewers reviewed and assessed these two types of papers (Fig. 1 ).

An outline of the study

Identifying peer-reviewed papers

As this study was conducted by researchers involved in rehabilitation sciences, only rehabilitation-related publications were considered. A researcher searched on PubMed in June 2023 using a search strategy involving: (“Neurological Rehabilitation”[Mesh]) OR (“Cardiac Rehabilitation”[Mesh]) OR (“Pulmonary Rehabilitation” [Mesh]) OR (“Exercise Therapy”[Mesh]) OR (“Physical Therapy”[Mesh]) OR (“Activities of Daily Living”[Mesh]) OR (“Self Care”[Mesh]) OR (“Self-Management”[Mesh]). English rehabilitation-related articles published between June 2013 and June 2023 in one of four high-impact journals ( Nature, The Lancet, JAMA, and British Medical Journal [BMJ] ) were eligible for inclusion. Fifty articles were included and categorized into four categories (musculoskeletal, cardiopulmonary, neurology, and pediatric) (Appendix 1 ).

Generating academic articles using ChatGPT

ChatGPT (GPT-3.5-Turbo, OpenAI, USA) was used to generate the introduction, discussion, and conclusion sections of fabricated articles in July 2023. Specifically, before starting a conversation with ChatGPT, we gave the instruction “ Considering yourself as an academic writer ” to put it into a specific role. After that, we entered “ Please write a convincing scientific introduction on the topic of [original topic] with some citations in the text” into GPT-3.5-Turbo to generate the ‘Introduction’ section. The ‘Discussion’ section was generated by the request “Please critically discuss the methods and results below: [original method] and [original result], Please include citations in the text” . For the ‘Conclusions’ section, we instructed ChatGPT to create a summary of the generated discussion section with reference to the original title. Collectively, each ChatGPT-generated article comprised fabricated introduction, discussion, and conclusions sections, alongside the original methods and results sections.

Rephrasing ChatGPT-generated articles using a paraphrasing tool

Wordtune (AI21 Labs, Tel Aviv, Israel) (Wordtune 2023 ), a widely used AI-powered writing assistant, was applied to paraphrase 50 ChatGPT-generated articles, specifically targeting the introduction, discussion, and conclusion sections, to enhance their authenticity.

Identification of AI-generated articles

Using ai content detectors.

Six AI content detectors, which have been widely used (Walters 2023 ; Crothers 2023 ; Top 10 AI Detector Tools 2023 ), were applied to identify texts generated by AI language models in August 2023. They classified a given paper as “human-written” or “AI-generated”, with a confidence level reported as an AI score [% ‘confidence in predicting that the content was produced by an AI tool’] or a perplexity score [randomness or particularity of the text]. A lower perplexity score indicates that the text has relatively few random elements and is more likely to be written by generative AI (GPTZero 2023 ). The 50 original articles, 50 ChatGPT-generated articles, and 50 AI-rephrased articles were evaluated for authenticity by two paid (Originality.ai, Originality. AI Inc., Ontario, Canada; and Turnitin’s AI writing detection, Turnitin LLC, CA, USA) and four free AI content detectors (ZeroGPT, Munchberg, Germany; GPTZero, NJ, USA; Content at Scale, AZ, USA; and GPT-2 Output Detector, CA, USA). The authentic methods and results sections were not entered into the AI content detectors. Since the GPT-2 Output Detector has a restriction of 510 tokens per attempt, each article was divided into several parts for input, and the overall AI score of the article was calculated based on the mean score of all parts.

Peer reviews by human reviewers

Four blinded reviewers with backgrounds in physiotherapy and varying levels of research training (two college student reviewers and two professorial reviewers) were recruited to review and discern articles. To minimize the risk of recall bias, a researcher randomly assigned the 50 original articles and 50 AI-rephrased articles (ChatGPT-generated articles after rephrasing) to two electronic folders by a coin toss. If an original article was placed in Folder 1, the corresponding AI-rephrased article was assigned to Folder 2. Reviewers were instructed to review all the papers in Folder 1 first and then wait for at least 7 days before reviewing papers in Folder 2. This approach would reduce the reviewers’ risk of remembering the details of the original papers and AI-rephrased articles on the same topic (Fisher & Radvansky 2018 ).

The four reviewers were instructed to use an online Google form (Appendix 2 ) to make their decision and provide reasons behind their decision. Reviewers were instructed to enter the article number on the Google form before reviewing the article. Once the reviewers had gathered sufficient information/confidence to make the decision, they would give a binary response (“AI-rephrased” or “human-written”). Additionally, they should select their top three reasons for their decision from a list of options (i.e., coherence creativity, evidence-based, grammatical errors, and vocabulary diversity) (Walters 2019; Lee 2022 ). The definitions of these reasons (Appendix 3 ) were explained to the reviewers beforehand. If they could not find the best answers, they could enter additional responses. When the reviewer submitted the form, the total duration was automatically recorded by the system.

Statistical analysis

Descriptive analyses were reported when appropriate. Shapiro-Wilk tests were used to evaluate the normality of the data, while Levene’s tests were employed to assess the homogeneity of variance. Logarithmic transformation was applied to the data related to ‘time taken’ to achieve the normal distribution. Separate two-way repeated measures analysis of variance (ANOVA) with post-hoc comparisons were conducted to evaluate the effect of detectors and AI usage on AI scores, and the effect of reviewers and AI usage on the time taken. Separate paired t-tests with Bonferroni correction were applied for pairwise comparisons. The GPTZero Perplexity scores were compared among groups of articles using one-way repeated ANOVA. Subsequently, separate paired t-tests with Bonferroni correction were used for pairwise comparisons. Receiver operating characteristic (ROC) curves were generated to determine cutoff values for the highest sensitivity and specificity in detecting AI articles by AI content detectors. The area under the ROC curve (AUROC) was also calculated. Inter-rater agreement was calculated using Fleiss’s kappa, and Cohen’s kappa with Bonferroni correction was used for multiple comparisons. The significance level was set at p  < 0.05. All statistical analyses were performed using SPSS (version 26; SPSS Inc., Chicago, IL, USA).

The accuracy of AI detectors in identifying AI articles

The accuracy of AI content detectors in identifying AI-generated articles is shown in Fig. 2 a and b. Notably, Originality.ai demonstrated perfect accuracy (100%) in detecting both ChatGPT-generated and AI-rephrased articles. ZeroGPT showed near-perfect accuracy (96%) in identifying ChatGPT-generated articles. The optimal ZeroGPT cut-off value for distinguishing between original and AI articles (ChatGPT-generated and AI-rephrased) was 42.45% (Fig. 3 a) , with a sensitivity of 98% and a specificity of 92%. The GPT-2 Output Detector achieved an accuracy of 96% in identifying ChatGPT-generated articles based on an AI score cutoff value of 1.46%, as suggested by previous research (Gao et al. 2023 ). Likewise, Turnitin showed near-perfect accuracy (94%) in discerning ChatGPT-generated articles but only correctly discerned 30% of AI-rephrased articles. GPTZero and Content at Scale only correctly identified 70 and 52% of ChatGPT-generated papers, respectively. While Turnitin did not misclassify any original articles, Content at Scale and GPTZero incorrectly classified 28 and 22% of the original articles, respectively. AI scores, or perplexity scores, in response to the original, ChatGPT-generated, and AI-rephrased articles from each AI content detector are shown in Appendix 4 . The classification of responses from each AI content detector is shown in Appendix 5 .

All AI content detectors, except Originality.ai, gave rephrased articles lower scores as compared to the corresponding ChatGPT-generated articles (Fig. 4 a). Likewise, GPTZero demonstrated that the perplexity scores of ChatGPT-generated (p<0.001) and AI-rephrased (p<0.001) texts were significantly lower than those of the original articles (Fig. 4 b) . The ROC curve of GPTZero perplexity scores for identifying original articles and AI articles showed that the respective AUROC were 0.312 (Fig. 3 b).

The accuracy of reviewers in identifying AI-rephrased articles

The median time spent by the four reviewers to distinguish original and AI-rephrased articles was 5 minutes (min) 45 seconds (s) (interquartile range [IQR] 3 min 42 s, 9 min 7 s). The median time taken by each reviewer to distinguish original and AI-rephrased articles is shown in Appendix 6 . The two professorial reviewers demonstrated extremely high accuracy (96 and 100%) in discerning AI-rephrased articles, although both misclassified 12% of human-written articles as AI-rephrased (Fig. 2 c and d , and Table 1 ). Although three original articles were misclassified as AI-rephrased by both professorial reviewers, they were correctly identified by Originality and ZeroGPT. The common reasons for an article to be classified as AI-rephrased by reviewers included ‘incoherence’ (34.36%), ‘grammatical errors’ (20.26%), ‘insufficient evidence-based claims’ (16.15%), vocabulary diversity (11.79%), creativity (6.15%) , ‘misuse of abbreviations’(5.87%), ‘writing style’ (2.71%), ‘vague expression’ (1.81%), and ‘conflicting data’ (0.9%). Nevertheless, 12 of the 50 original articles were wrongly considered AI-rephrased by two or more reviewers. Most of these misclassified articles were deemed to be incoherent and/or lack vocabulary diversity. The frequency of the primary reason given by each reviewer and the frequency of the reasons given by four reviewers for identifying AI-rephrased articles are shown in Fig. 5 a and b, respectively.

Regarding the inter-rater agreement between two professorial reviewers, there was near-perfect agreement in the binary responses, with κ = 0.819 (95% confidence interval [CI] 0.705, 0.933, p <0.05), as well as fair agreements in the primary and second reasons, with κ = 0.211 (95% CI 0.011, 0.411, p <0.05) and κ = 0.216 (95% CI 0.024, 0.408, p <0.05), respectively.

“Plagiarized” scores of ChatGPT-generated or AI-rephrased articles

Turnitin results showed that the content of ChatGPT-generated and AI-rephrased articles had significantly lower ‘plagiarized’ scores (39.22% ± 10.6 and 23.16% ± 8.54%, respectively) than the original articles (99.06% ± 1.27%).

Likelihood of ChatGPT being used in original articles after the launch of GPT-3.5-Turbo

No significant differences were found in the AI scores or perplexity scores calculated by the six AI content detectors (p>0.05), or in the binary responses evaluated by reviewers ( p >0.05), when comparing the included original papers published before and after November 2022 (the release of ChatGPT).

Our study found that Originality.ai and ZeroGPT accurately detected AI-generated texts, regardless of whether they were rephrased or not. Additionally, Turnitin did not misclassify human-written articles. While professorial reviewers were generally able to discern AI-rephrased articles from human-written ones, they might misinterpret some human-written articles as AI-generated due to incoherent content and varied vocabulary. Conversely, AI-rephrased articles are more likely to go unnoticed by student reviewers.

What is the performance of generative AI in academic writing?

Lee et al found that sentences written by GPT-3 tended to generate fewer grammatical or spelling errors than human writers (Lee 2022 ). However, ChatGPT may not necessarily minimize grammatical mistakes. In our study, reviewers identified ‘grammatical errors’ as the second most common reason for classifying an article as AI-rephrased. Our reviewers also noted that generative AI was more likely to inappropriately use medical terminologies or abbreviations, and even generate fabricated data. These might lead to a detrimental impact on academic dissemination. Collectively, generative AI is less likely to successfully create credible academic articles without the development of discipline-specific LLMs.

Can generative AI generate creative and in-depth thoughts?

Prior research reported that ChatGPT correctly answered 42.0 to 67.6% of questions in medical licensing examinations conducted in China, Taiwan, and the USA (Zong 2023 ; Wang 2023 ; Gilson 2023 ). However, our reviewers discovered that AI-generated articles offered only superficial discussion without substantial supporting evidence. Further, redundancy was observed in the content of AI-generated articles. Unless future advancements in generative AI can improve the interpretation of evidence-based content and incorporate in-depth and insightful discussion, its utility may be limited to serving as an information source for academic works.

Who can be deceived by ChatGPT? How can we address it?

ChatGPT is capable of creating realistic and intelligent-sounding text, including convincing data and references (Ariyaratne et al. 2023 ). Yeadon et al , found that ChatGPT-generated physics essays were graded as first-class essays in a writing assessment at Durham University (Yeadon et al. 2023 ). We found that AI-generated content had a relatively low plagiarism rate. These factors may encourage the potential misuse of AI technology for generating written assignments and the dissemination of misinformation among students. In a current survey, Welding ( 2023 ) reported that 50% of 1000 college students admitted to using AI tools to help complete assignments or exams. However, in our study, college student reviewers only correctly identified an average of 76% of AI-rephrased articles. Notably, our professorial reviewers found fabricated data in two AI-generated articles, while the student reviewers were unaware of this issue, which highlights the possibility of AI-generated content deceiving junior researchers and impacting their learning. In short, the inherent limitations of ChatGPT as reported by experienced reviewers may help research students understand some key points in critically appraising academic articles and be more competent in detecting AI-generated articles.

Which detectors are recommended for use?

Our study revealed that Originality.ai emerged as the most sensitive and accurate platform for detecting AI-generated (including paraphrased) content, although it requires a subscription fee. ZeroGPT is an excellent free tool that exhibits a high level of sensitivity and specificity for detecting AI articles when the AI score threshold is set at 42.45%. These findings could help monitor the AI use in academic publishing and education, to promisingly tackle ethical challenges posed by the iteration of AI technologies. Additionally, Turnitin, a widely used platform in educational institutions or scientific journals, displayed perfect accuracy in detecting human-written articles and near-perfect accuracy in detecting ChatGPT-generated content but was proved susceptible to deception when confronted with AI-rephrased articles. This raises concerns among educators regarding the potential for students to evade Turnitin AI detection by using an AI rephrasing editor. As generative AI technologies continue to evolve, educators and researchers should regularly conduct similar studies to identify the most suitable AI content detectors.

AI content detectors employ different predictive algorithms. Some publicly available detectors use perplexity scores and related concepts for identifying AI-generated writing. However, we found that the AUROC curve of GPTZero perplexity scores in identifying AI articles performed worse than chance. As such, the effectiveness of utilizing perplexity-based methods as the machine learning algorithm for developing an AI content detector remains debatable.

As with any novel technology, some merits and demerits require continuous improvement and development. Currently, AI content detectors have been developed as general-purpose tools to analyze text features, primarily based on the randomness of word choice and sentence lengths (Prillaman 2023 ). While technical issues such as algorithms, model turning, and development are beyond the scope of this study, we have provided empirical evidence that offers potential directions for future advancements in AI content detectors. One such area that requires further exploration and investigation is the development of AI content detectors trained using discipline-specific LLMs.

Should authors be concerned about their manuscripts being misinterpreted?

While AI-rephrasing tools may help non-native English writers and less experienced researchers prepare better academic articles, AI technologies may pose challenges to academic publishing and education. Previous research has suggested that AI content detectors may penalize non-native English writers with limited linguistic expressions due to simplified wording (Liang et al. 2023 ). However, scientific writing emphasizes precision and accurate expression of scientific evidence, often favouring succinctness over vocabulary diversity or complex sentence structures (Scholar Hangout 2023 ). This raises concerns about the potential misclassification of human-written academic papers as AI-generated, which could have negative implications for authors’ academic reputations. However, our results indicate that experienced reviewers are unlikely to misclassify human-written manuscripts as AI-generated if the articles present logical arguments, provide sufficient evidence-based support, and offer in-depth discussions. Therefore, authors should consider these factors when preparing their manuscripts to minimize the risk of misinterpretation.

Our study revealed that both AI content detectors and human reviewers occasionally misclassified certain original articles as AI-generated. However, it is noteworthy that no human-written articles were misclassified by both AI-content detectors and the two professorial reviewers simultaneously. Therefore, to minimize the risk of misclassifying human-written articles as AI-generated, editors of peer-reviewed journals may consider implementing a screening process that involves a reliable, albeit imperfect, AI-content detector in conjunction with the traditional peer-review process, which includes at least two reviewers. If both the AI content detectors and the peer reviewers consistently label a manuscript as AI-generated, the authors should be given the opportunity to appeal the decision. The editor-in-chief and one member of the editorial board can then evaluate the appeal and make a final decision.

Limitations

This study had several limitations. Firstly, the ChatGPT-3.5 version was used to fabricate articles given its popularity. Future studies should investigate the performance of upgraded LLMs. Secondly, although our analyses revealed no significant differences in the proportion of original papers classified as AI-written before and after November 2022 (the release of ChatGPT), we cannot guarantee that all original papers were not assisted by generative AI in their writing process. Future studies should consider including papers published before this date to validate our findings. Thirdly, although an excellent inter-rater agreement in the binary score was found between the two professorial reviewers, our results need to be interpreted with caution given the small number of reviewers and the lack of consistency between the two student reviewers. Future studies should address these limitations and expand our methodology to include other disciplines/industries with more reviewers to enhance the generalizability of our findings and facilitate the development of strategies for detecting AI-generated content in various fields.

Conclusions

This is the first study to directly compare the accuracy of advanced AI detectors and human reviewers in detecting AI-generated medical writing after paraphrasing. Our findings substantiate that the established peer-reviewed system can effectively mitigate the risk of publishing AI-generated academic articles. However, certain AI content detectors (i.e., Originality.ai and ZeroGPT) can be used to help editors or reviewers with the initial screening of AI-generated articles, upholding academic integrity in scientific publishing. It is noteworthy that the current version of ChatGPT is inadequate to generate rigorous scientific articles and carries the risk of fabricating data and misusing medical abbreviations. Continuous development of machine-learning strategies to improve AI detection accuracy in the health sciences field is essential. This study provides empirical evidence and valuable insights for future research on the validation and development of effective detection tools. It highlights the importance of implementing proper supervision and regulation of AI usage in medical writing and publishing. This ensures that relevant stakeholders can responsibly harness AI technologies while maintaining scientific rigour.
