GPTZero Reviews 

Tested it out and it tells me something 100% written by me was 97% AI generated. Quillbot recognizes it's human written. Sorry, gptzero doesn't work.
I scanned the same text twice and got different results as well.

I enjoy the constructive feedback. The grading tool is particularly helpful.

This is the best app and I don’t joke with it. The only trust app I rely on to do my assignments.

It is definetly the best website to check for AI that i have used. I feel like the website is easy to the eye and welcoming for new users.

It helped me correct a lot of assignments. It is a great website! 100% reccomend it .

Great platform! I have detected so many of my educational documents as having AI!

Request for Cancellation and Full Refund – GPTZero

Dear GPTZero Support Team,

I recently purchased a GPTZero Professional subscription on March 17, 2025, for $45.99. However, after attempting to use the service, I have encountered persistent errors and have been unable to obtain any accurate or useful information. Given these issues, I am extremely dissatisfied with the service, which does not function as advertised.

I am requesting an immediate cancellation of my subscription and a full refund as the service is not meeting its intended purpose. Please confirm the cancellation and refund at your earliest convenience.

GPTZero is a scam. I'm a copywriter and AI-generated content editor (humanized) and a client told me they use GPTZero to test writers' work. I took their AI-generated content and edited it. I copied it into Quillbot and ZeroGPT and they gave me scores of 0%, but GPTZero gave it 100% AI written. That's not possible since I edited it myself. Then I entered a poem I wrote in the 90s as a child (long before AI or ChatGPT) and it spat out a score of 65% AI written. How is that possible? DO NOT use this software to judge writers and students! I am disgusted by this website. It should be taken down.

I've been using GPTZero and it's been amazing at everything. 100% would recommend downloading and purchasing plan to enjoy it fully

This tool is a total scam, it gives too many false positives flagging an entire paragraph as “AI generated” just for using 1 or 2 technical or formal words that are very common in essays, application/motivation letters.

I absolutely would not recommend it for reviewing any formal document, paper or essay… It’s basically snake oil

only correct AI detector. not 100% accurate, but the best option

It gave me some really interesting feedback and also told me what A.I.-sounding sentences I should change. Super helpful in my 7-page research essay on computer processing chips. Highly recommend!

GPTZERO helped me finish correcting my students' assignments within minutes after being used to spending hours to complete the task. It also facilitated the process of giving feedback on their writing. It is a very useful tool

I was very happy with the results of this checker it pointed out clear and understanding results for my students papers.

There are too many ads to sort out/to go through before I can start uploading the test material to be investigated. Three times, I had to leave the page to refresh.

It's been a wonderful experience using GPTzero to check for AI assistance. I have become so cool with using it always.

Help me detect and prevent plagiarism, the platform has been incredibly helpful in ensuring the originality of my work and i deeply appreciate the accuracy and eficiency it offers

This is a great tool for me to quickly scan text to determine the likelihood that it is AI generated. It is easy to use and the interface is very user-friendly.

ChatGPTZero has been really useful for checking if something was written by AI. It’s quick, easy to use, and gives a clear breakdown of its results. I’ve tested it on different types of writing, and it does a solid job of flagging AI-generated content.

The confidence scores are helpful, and I appreciate that it doesn’t just say “AI” or “human” but actually explains why. Definitely a useful tool for educators, writers, or anyone who wants to verify content authenticity.
