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:

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

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

  • 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.
