Grammarly is a popular writing and editing tool used by writers, students, and professionals. So, if you write or edit regularly, chances are you’ve heard of or used Grammarly. 

It goes far beyond the typical spelling and grammar checks of many word-processing programs. Grammarly also uses generative AI (in certain features) to suggest recommendations, with the aim of making writing clearer and easier to understand. 

Then, in addition to Grammarly's use of generative AI to enhance its features, it also offers a plagiarism checker and a Grammarly AI detector within its suite of tools.

Considering that the platform uses AI for ‘Rewrite’ or ‘Rephrase’ features, you may be wondering — does Grammarly detect AI and plagiarism? In this article, we’ll take a closer look at how Grammarly works and how it compares to Originality.ai when detecting plagiarism and AI writing

What Is Grammarly and What Are Its Features?

According to Crunchbase, Grammarly was launched in 2009. Initially, its primary focus was a spelling and grammar checker for academia and students. Since then, it has quickly become a must-have editing tool for professionals that includes a suite of features such as:

  • A paraphrasing tool
  • Citation generator
  • Tone detector
  • Plagiarism checker
  • A selection of AI writing tools

With app and browser extensions, it’s accessible just about anywhere you want to write. 

One of the platform’s hallmark features is its ability to check grammar and spelling in real time. While you’re typing, Grammarly works in the background, catching grammatical errors, misspellings, punctuation problems, and much more. 

It provides detailed tips, suggestions, and recommendations for clarity, even offering to “Rewrite” the content to match a specific tone or style. This type of in-depth checking process is part of why the platform is so popular.

Does Grammarly detect AI and plagiarism?

It’s no secret that for Grammarly, generative AI is part of its features. However, while it does offer a plagiarism checker, it hasn’t yet released any details about providing AI detection.

So, no — Grammarly does not yet detect AI and plagiarism —  it only offers plagiarism detection.

Grammarly Generative AI Writing

Although Grammarly is incredibly popular for improving things like grammar, spelling and clarity, it surprisingly doesn’t have a dedicated feature specifically for detecting AI writing. 

The platform’s main focus is helping to improve writing, and uses Grammarly generative AI in the same vein to make suggestions, recommendations and at times, rewrites. 

In one of Grammarly’s Common Question guides, they note that ‘foundational AI technology’ is integrated into the platform and doesn’t impact original human writing. Then, since the initial adoption of AI, they have expanded to include generative AI, “In 2023, Grammarly introduced optional generative AI features that enable users to produce new content based on their inputs or prompts.

So, Grammarly's generative AI is incorporated into the technology with the aim of going beyond ordinary spelling and grammar checkers. For example, it might flag text that reads as overly formal, repetitive, or lacking in voice and offer the option to generate or ‘produce new content’ based on this.

When using generative AI with Grammarly, it’s possible that the newly rewritten or rephrased text will trigger AI detection.

However, features like spelling and grammar checks aren’t necessarily considered AI writing to AI detectors (though this can vary by model and product). Originality.ai’s newly released 1.0.0 Lite AI detector model allows for light AI editing, like spelling and grammar suggestions.

Grammarly and Plagiarism Detection

Grammarly’s plagiarism checker is incredibly valuable. It works by scanning your text against everything from billions of web pages to academic databases (ProQuest). It looks for matches between the submitted text and highlights them as duplicate content

Citation features with plagiarism detection

Depending on the pricing plan, it also offers citation suggestions to help you avoid plagiarism. One of the key hallmarks of plagiarism is copying someone else’s content without proper attribution. 

Grammarly suggests citations according to the most commonly used citation methods, such as APA or MLA, making it an incredibly helpful resource for students and professionals alike who need to adhere to strict academic or publishing standards.

  • Benefits for students: having access to proper citation guidelines can serve as an excellent refresher before turning in an essay. 
  • Perks for educators: the ability to see the sources that Grammarly highlights as potential plagiarism, allows for additional human reviews.

The free version of their plagiarism tool is available on their website. Then, for additional features like recommendations on citing source material, Premium options are available.

Despite accessing and crawling through such a massive database to find matches, the plagiarism detection process typically only takes a few minutes. 

Keep in mind that there's always a chance of false positives. False positives can occur if your content uses common phrases or widely cited quotations. For this reason, it’s always a good idea to have a “human-in-the-loop” to verify potential instances of plagiarism. 

Comparison: Originality.ai Offers AI and Plagiarism Detection

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?
