Review summary

Created with AI, based on recent reviews

Looking at 42 reviews, most reviewers were unhappy with their experience overall. Many customers found the product to be an unhelpful and often useless tool for its intended purpose. Reviewers consistently reported that the artificial intelligence detection was highly inaccurate. This inaccuracy frequently led to human-written content being incorrectly flagged as AI-generated. People expressed frustration with the tool marking eloquent sentences, formal writing, or even quotes as AI. Several customers noted that texts written years before AI chatbots existed were also incorrectly identified as AI. This led to a frustrating user experience, with some feeling forced to distort their writing or wasting time trying to understand the flags. The product was described as unreliable and dysfunctional, suffering from lag and providing misleading results.

It was quite useful until all the humanizing models came. Now, it highlights more than half the text as AI and tells you 2% AI. I don't get it. Also, there is no one to reach out to for customer se... See more

I couldn't cancel my free trial

I couldn't cancel my free trial. Every time I clicked on this option, I was forwarded to a page without any corner to proceed with the cancellation. This is too wrong to force you to continue with the subscription even if you want to cancel during the free trial. There are fairer ways to make money, such as offering a well-provided and useful service. This is not the case with this platform.

Best AI detector

I feel like there isn’t any AI detector better. Even with the free plan it gives a great summary and tells you if the text seems ai generated
and once you buy the plan it has options to break down the text and tell you cool things like common AI used words etc.
I’ve used it a lot and also it’s best to get an account because it saves your documents and gives you cool stats

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.me is fraudulant

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.
