Undetectable AI: StealthGPT Reviews 194

Best humanizer I've tried so far. Good software and quality writing that passes detectors. I'd highly recommend this. Price a bit too high though, but it delivers so I guess it's worth it?

Overall the software delivers pretty well. It's got some hallucination problems, but without enough context, there's not a whole lot you can do about that. But when I tried to cancel my subscription, it took me through a seemingly endless barrage of attempts to try to get me to stop. I must have misclicked on one of the pages and it did not in fact cancel the subscription. I didn't realize until much later that I had been charged $13/week since. When I reached out to their support team they denied me a refund for the unused weeks. If I haven't used any tokens and have cost the company $0, I should receive my money back.

Horrible the quality, sentences out of sens, mistakes..

Fast and effective customer support, such a pleasant experience.

I registered an account and subscribed monthly on 8 May. However, when I checked my account today, 24 May, I discovered my subscription had been cancelled without my permission. It should have lasted until 8 June. No notice, no refund, no contacts.
THE SUPPORT WEBSITE EVEN SHOWS ERROR 404
SCAM
A response to stealth gpt: yes, of course I did not reach out to the support team, because your support website SHOWS 404!!!!!

Very responsive

Josh from Customer support was very helpful and quick with his responses.

Fantastic and proactive customer service. The App/Software has been helpful. Better by far than the rest ive came across.

The AI Humanizer way out preformed the similarly priced Quillbot which only has a "rephrase it" feature with a few different versions of rephrasing each all cost more than the other. StealthGPT offers a wide range of products not only for students but entrepreneurs and writers. For anyone in college, college aged, or starting a new communications type business I highly recommend StealthGPT

I am a professional copywriter and often need to employ AI tools to keep up with today's market demands. StealthGPT provides me with clear, readable, and humanized copy that I can then integrate into a high value and informative page. I frequently use both the AI Humanizer and have been excited to try the newly released Stealth Agent content writer.

Enterprise plan has everything that I need. Great customer service as well

What a load of rubbish!

No way to even test if it works... straight to payment subscription! Wow. These apps get more and more greedy. If you don't let users see or test how anything even works! Do you really expect us to just sign up £29.99 a month and be happy to hand over money month after month! haha ridiculous.

I do not recommend this

Great customer service! Very fast reply to my email, extremely friendly and efficient. Thank you!

Had several issues with my subscription and with my account. Their team went above and beyond in order to help solve my issue.

Ongoing Unauthorized Charges & Misleading Subscription Practices

I signed up for a free trial of StealthGPT and canceled it shortly afterward. I did not continue using the service and never authorized ongoing monthly charges.

Despite this, I was charged $14.99 per month from February 2024 through January 2026, totaling $359.76 over two years — without my knowledge or consent.

When I contacted customer support, they refused to issue a full refund for these unauthorized charges. Once I informed them I would escalate the matter to my bank, they stopped responding and sent only a generic website link instead of addressing the issue.

Additionally, when accessing their platform through related branding (such as “Undetectable AI”), the interface and billing page appeared identical to the original StealthGPT trial page, which raises serious concerns about transparency and subscription clarity.

This pattern reflects misleading billing practices and a lack of accountability. I have initiated a formal dispute with my credit card company and will continue pursuing this matter through appropriate consumer protection channels.

Great! Very quick response times!

Quick and easy, they were fast to respond and resolve my issue thanks guys!

used to work well for me, new recent update came around and every time i prompt something in and run it through the ai checker it gives me 100% ai generated. it's pretty annoying considering that the whole business model for the company is the fact we are paying money for the promise that the ai is untraceable, which as of lately is just false advertisement. idk what yall did but it needs to go back the way it was when it actually worked.
