Does Turnitin Detect Grammarly?

No, Turnitin is not designed to detect any changes, such as spelling, punctuation, grammar, or paraphrasing by Grammarly. Its main goal is to catch content written by AI tools, such as those using models like GPT-3.5. Grammarly is designed to help writers of all types, including students, authors, and professionals, by improving their writing.

Here is exactly how Turnitin responds to users’ inquiries:

No, Our detector is not tuned to target Grammarly-generated spelling, grammar, and punctuation modifications to the content… In most cases, changes made by Grammarly (free & premium) and/or other grammar-checking tools were not flagged as AI-written by our detector.”—Karen Smith, Senior Learning Innovations Specialist at Turnitin.

Because Turnitin is only licensed for educational institutions, individuals do not have access to it. Alternatively, you can consider using Originality.ai. It claims to achieve an accuracy range of 90.2% to 98.8% at detecting AI content with a false positive rate of 2.8%.

If your article passes Originality.ai, it will likely also pass Turnitin.

“GrammarlyGo, which is a generative AI writing tool and as such content produced using this tool will likely be flagged as AI-generated by our detector.”— Karen Smith, Senior Learning Innovations Specialist at Turnitin. (Source: Turnitin Forum)

5 Best Practices for Using Grammarly For Turnitin

If you want to make sure your work goes smoothly through Turnitin, here are some easy tips for using Grammarly:

  • Stick to the Basics: Use Grammarly mainly for checking grammar, spelling, and punctuation. These basic edits are safe and won’t trigger any issues in Turnitin.
  • Save Your Originals: Always keep a copy of your original work before you dive into Grammarly’s suggestions. This way, you’ll have a reference if anyone questions the originality of your work.
  • Limit AI Features: Try not to rely too much on Grammarly’s AI features, like paraphrasing or content generation. While they can be helpful, they may increase the likelihood that your work will be flagged as AI-generated content by Turnitin.
  • Make It Feel Human: If you want your content to sound more natural and less AI-generated, consider using tools like Undetectable AI or StealthWriter. They can help adjust the tone and style of your writing.
  • Cite Properly: Always cite the original source when using someone else’s ideas or materials, whether it’s text, images, or data, from any source, like books, articles, or websites. Tools like Paperpal can simplify this by helping you create accurate citations in formats like APA, MLA, or Chicago.
  • Double-Check for Plagiarism & AI: Since accessing Turnitin can be difficult, it’s important to double-check your work using other plagiarism-checking tools and AI detectors. You can consider using Originality.ai or Winston AI, which are commonly used by teachers.

In today’s academic landscape, the use of AI paraphrasing tools, such as Grammarly and Quillbot, has become increasingly common.
