lucy,  I am a student doing a Master's, and English is my 3rd language, so yes, I use the Grammarly app to correct my grammar, but I have been flagged by AI even though I wrote my ideas. It hurts me after putting so much effort into my papers, and I don't feel like writing anymore. It is discouraging me to write my research paper. No matter how hard I try, it is flagged by AI. If I used AI and got flagged, I wouldn't be doing this research, reading all the reviews, and replying to you. My student life was beautiful when I was doing my bachelor's in 2017 before turnitin and before ChatGPT. Even if I wrote my own words, AI flagged everything now, if I use Grammarly. One of my friends had a PhD; he uploaded his old research paper, which was AI-detected. His research paper was done way before ChatGPT.\ I even uploaded my research paper on chatgpt and asked whether it was written by humans or AI-generated, and it said written by a human. This Turnitin is ruining my life. 

simchi marak I think it's been pretty well proven that ChatGPT can't accurately detect whether text was AI produced or not.

Steve Bentley, Thank you for the response. It might be true, but it was written by me, and copied-paste my paper to the chatgpt and wrote whether it was written by humans or AI-generated, this was the result chatgpt provided “it appears to be human written” and I believe it because it was actually written by human. 

simchi marak But the fact is that you are asking a system which does not know how to distinguish between human written and AI written material, you may as well toss a coin.

Steve Bentley, I believe, even turnitin as well, because my paper was detected AI even though I wrote it myself. However, I used the Grammarly app to correct spelling and grammar. On my first paper, I was detected as 9% AI. I took this cautiously, and yes, I used the Grammarly app, on the second paper I was detected 81% which made me upset and hurt after I put so much effort into it and on my final paper, it was 20% AI detected, I used the Grammarly app as well, but I used it where it was necessary I don't use it for all the papers, but I lost points on my grammar still detected 20% so I begin to research on Google, quora and Reddit that if we use Grammarly app can turnitin detect AI or not.

simchi marak Turnitin themselves say that an AI score of 20% or lower is highly likely to be a false positive, so I wouldn't be concerned.

There are certainly points about Grammarly which need to be clarified, and the AI detection has opened up a huge discussion at my institution about whether allowing Grammarly to rewrite large portions of your work (compared with having it provide suggestions that you choose whether to act upon) is acceptable or not. 

If you are losing points for grammar errors - ie the grammar is part of the assessment criteria - I would be surprised if using Grammarly to rewrite the work was permitted, but that's a matter for your institution.

lucy When you say 'no AI detection', do you mean no AI use % or 0%? I've had a situation where Turnitin was returning no result for a test document I'd uploaded using an AI-generated article summary. Another colleague uploaded the same document and received a 50% AI score. The issue is fixed now (took about four weeks) but it does raise questions about the reliability of the tool.

I’ve had the same issue recently. I did my assessment on WordDoc, copied it into Grammarly, pasted it back into WordDoc and I’ve been flagged 100% AI when the work is 100% mine. So upsetting and demotivating. simPsych 

Marjorie Pereira I know this is an old post, but this is incorrect, it just guesses. And certainly in my institution pasting a student's work into GPT would breach the student's IP rights.
