Since the inception of mainstream AI content generation back in 2022, there has been a constant clamor to find a solution to people passing this content off as their own, human-written work.

While other brands have used the term ‘AI content detector’ as a marketing ploy for a poor-at-best product, Originality.ai has always strived to provide the most in-depth and detailed tool possible in an attempt to bring honesty and transparency to the world of AI content detection.

However, that doesn’t mean that false positives don’t occur from time to time, which can cause significant issues for brands, writers, students, and many more.

From our discussions with users, many of these issues seem to stem from the use of tools like Grammarly, which is why we decided to put it to the test ourselves.

Short on time? Here are the key takeaways

  1. When using Grammarly for spelling or grammatical errors, the impact regarding AI content detectors is minimal.
  2. When using Grammarly’s rewrite and rephrase features, this can lead to content getting flagged as AI-generated.
  3. Wherever possible, always strive to be transparent and open about the tools you use for creating content, and save original versions for clarity if required.

Can Grammarly Detect AI Writing

Does Using Grammarly Get Content Detected as AI Generated?

What is Grammarly?

Grammarly is a writing assistance tool that helps users improve their writing by checking for grammatical errors, punctuation mistakes, spelling errors, and style issues. 

Additionally, it provides insights into sentence structure, vocabulary usage, tone, and readability, aiming to assist writers in crafting clear and compelling content.

It’s a brilliant tool, and one that can greatly support writers in any vocation, whether it be book writing, marketing, or academia.

Grammarly also provides rephrasing suggestions, using it’s AI to identify a more common way of structuring a particular sentence, or a way that is less wordy, or one that is more suitable to your selected target audience.

What is a False Positive?

A false positive refers to a situation in which a test or evaluation incorrectly indicates the presence of something that is not actually there or incorrectly identifies a condition as being present. 

For example, you have written a piece of content entirely on your own, only to see it flagged as AI-generated when you run it through Originality.ai.

This is an issue that some of our users were experiencing, whereby their original content would pass through Originality’s detectors with no issues, but the version that had been run through Grammarly for amends first was flagging as AI-generated.

The Test

To test this theory and identify what specific element of Grammarly could be causing the problem, we decided to do our own testing. After all, Grammarly isn’t just a spell-checker, it also offers AI-generated rephrasing suggestions and wording changes, so it’s important to identify which aspects are causing false positives to occur.

To do this, we gathered ten known human IELTS essay answers as our benchmark and ran each of those pieces of content through Originality Standard 2.0 for clarity (note: this model is retired, for details on our latest model visit our AI Detector Accuracy Review). We then proceeded to break down our amends into two different categories:

Lightly edited: With this version of the content we only accepted Grammarly grammar suggestions, and not any rephrase or rewrite suggestions.

Heavily edited: With this version, we accepted all Grammarly insights, including rephrasing and rewriting suggestions.

You can find the data for our test here.

The Findings

grammarly use trigger ai detection

As you can see from the results, light edits resulted in almost all of the examples continuing to display as human-written, whereas the heavy edits had a significant impact on whether or not the content was flagged as AI-generated.

This makes sense when you consider that the more you rely on the AI suggested edits and phrasing changes from tools like Grammarly, the less the work reads like your original draft, and the more of it is based on AI suggestions.

While this is only a small sample size, it gives us a good indication of how much impact overly relying on these tools can have on your AI content detection score.

Originality.ai's Content Policy With Grammarly

To clarify Originality.ai’s content policy on Grammarly and AI detection, we’ve included a brief update to this article as of June 20th, 2024. 

Please note that as Grammarly releases new features and as our machine learning engineers at Originality.ai continue to improve accuracy and lower false positives, this policy may change and be updated at a later date.

How to avoid false positives

False positives occur when copy or content that a person writes is incorrectly identified as AI-generated. 

To lower the risk of false positives when using the Originality.ai detector:

  • Focus on writing unique, original content.
  • Use AI writing and editing tools sparingly (avoid Grammarly’s Rephrase, Rewrite, and Use our best version features).
  • When you scan your copy with the Originality.ai AI detector, include the entire version (instead of a single paragraph).
  • Monitor the AI score of your content by using the Originality.ai ‘Watch a Writer Write’ Google Chrome Extension.

For additional information on reducing false positives, read these articles:

Grammarly features that aren’t considered AI writing

Grammar and spelling suggestions from Grammarly aren’t considered AI writing. The grammar and spelling correction features are editing tools that are unlikely to trigger AI detection.

Grammarly features that trigger AI detection due to AI writing

Although grammar and spelling suggestions are unlikely to trigger AI detection, Grammarly’s Rephrase, Rewrite, and Use our best version — prompt AI detection.

On Grammarly’s features page, they note that they integrate ‘generative AI’ to power certain features. Although AI can be an excellent tool for improving writing skills, it’s important to be aware that if you edit with Rephrase, Rewrite, and Use our best version, it could trigger AI detection. 

To avoid issues, it’s best practice to clarify a client’s guidelines on the use of AI-powered writing and editing tools like Grammarly at the beginning of a project

Additionally, Grammarly also recommends providing proper citations when using AI rewriting tools, such as their Paragraph Rewriter.

Grammarly has launched its own AI detector which is reviewed here.

In Summary

So, in summary, when users of Grammarly use the "Rephrase" or "Rewrite" suggestions, it is likely to trigger AI detectors to identify the content as AI-written. If it is used for spelling, not so much. 

That is why it’s essential always to be transparent with what tools you use and maybe even save an original version of the document before using Grammarly to make any changes. That way, if any issues arise, you can provide the original document for clarity.

Frequently Asked Questions

Do I have to fill out the entire form?

No, that’s one of the benefits, only fill out the areas which you think will be relevant to the prompts you require.

Why is the English so poor for some prompts?

When making the tool we had to make each prompt as general as possible to be able to include every kind of input. Not to worry though ChatGPT is smart and will still understand the prompt.

Frequently Asked Questions

Why is it important to check for plagiarism?

Tools for conducting a plagiarism check between two documents online are important as it helps to ensure the originality and authenticity of written work. Plagiarism undermines the value of professional and educational institutions, as well as the integrity of the authors who write articles. By checking for plagiarism, you can ensure the work that you produce is original or properly attributed to the original author. This helps prevent the distribution of copied and misrepresented information.

What is Text Comparison?

Text comparison is the process of taking two or more pieces of text and comparing them to see if there are any similarities, differences and/or plagiarism. The objective of a text comparison is to see if one of the texts has been copied or paraphrased from another text. This text compare tool for plagiarism check between two documents has been built to help you streamline that process by finding the discrepancies with ease.

How do Text Comparison Tools Work?

Text comparison tools work by analyzing and comparing the contents of two or more text documents to find similarities and differences between them. This is typically done by breaking the texts down into smaller units such as sentences or phrases, and then calculating a similarity score based on the number of identical or nearly identical units. The comparison may be based on the exact wording of the text, or it may take into account synonyms and other variations in language. The results of the comparison are usually presented in the form of a report or visual representation, highlighting the similarities and differences between the texts.

String comparison is a fundamental operation in text comparison tools that involves comparing two sequences of characters to determine if they are identical or not. This comparison can be done at the character level or at a higher level, such as the word or sentence level.

The most basic form of string comparison is the equality test, where the two strings are compared character by character and a Boolean result indicating whether they are equal or not is returned. More sophisticated string comparison algorithms use heuristics and statistical models to determine the similarity between two strings, even if they are not exactly the same. These algorithms often use techniques such as edit distance, which measures the minimum number of operations (such as insertions, deletions, and substitutions) required to transform one string into another.

Another common technique for string comparison is n-gram analysis, where the strings are divided into overlapping sequences of characters (n-grams) and the frequency of each n-gram is compared between the two strings. This allows for a more nuanced comparison that takes into account partial similarities, rather than just exact matches.

String comparison is a crucial component of text comparison tools, as it forms the basis for determining the similarities and differences between texts. The results of the string comparison can then be used to generate a report or visual representation of the similarities and differences between the texts.

What is Syntax Highlighting?

Syntax highlighting is a feature of text editors and integrated development environments (IDEs) that helps to visually distinguish different elements of a code or markup language. It does this by coloring different elements of the code, such as keywords, variables, functions, and operators, based on a predefined set of rules.

The purpose of syntax highlighting is to make the code easier to read and understand, by drawing attention to the different elements and their structure. For example, keywords may be colored in a different hue to emphasize their importance, while comments or strings may be colored differently to distinguish them from the code itself. This helps to make the code more readable, reducing the cognitive load of the reader and making it easier to identify potential syntax errors.

How Can I Conduct a Plagiarism Check between Two Documents Online?

With our tool it’s easy, just enter or upload some text, click on the button “Compare text” and the tool will automatically display the diff between the two texts.

What Are the Benefits of Using a Text Compare Tool?

Using text comparison tools is much easier, more efficient, and more reliable than proofreading a piece of text by hand. Eliminate the risk of human error by using a tool to detect and display the text difference within seconds.

What Files Can You Inspect with This Text Compare Tool?

We have support for the file extensions .pdf, .docx, .odt, .doc and .txt. You can also enter your text or copy and paste text to compare.

Will My Data Be Shared?

There is never any data saved by the tool, when you hit “Upload” we are just scanning the text and pasting it into our text area so with our text compare tool, no data ever enters our servers.
