100% Scam. Paused my weekly subscription but they magically unpaused it without prior notice and charged me twice. Support refused to refund, instead canceling my account completely, removing my access to the platform and my old data.
Also unsatisfied with product. Text humanizer repeatedly caught by detectors.

I just finished up my Senior year
I just finished up my Senior year in university and StealthGPT was a big part of helping my cross the finish line. Some context, I had already secured employment as and jr auditor/QC in finance in early April, they wanted me to start then. I didn't want to say no, but still had a full course load on my plate. I buckled down and looked for the best AI writing companion I could find and came across Stealth. With a 15 credit course load and a full time job, I was able to utilize the tools (really the AI Humanizer) in StealthGPT to make sure the few none work hours I had didn't go to waste. Thanks to the team for this awesome tool, I really owe you all.

Super helpful!
StealthGPT has been a huge help for me. I write blog articles and this does a great job at creating and keeping them from being detected!
Josh from Support was very helpful and responsive when I needed to change my work credit card. Thanks Josh!

Avoid StealthGPT AT ALL COSTS!!...humanizer does not work & software is just a subscription fee trap!!! Customer service will not help you or care
I signed up for StealthGPT to use the Humanizer feature and was extremely disappointed.
The software simply does not work as advertised. Not only did the output still fail AI detection tools, but the quality of the writing was terrible. The text was full of grammatical mistakes, awkward phrasing and unnatural sentence structures. In many cases it was almost illegible. Rather than sounding human, the output often read like it had been written by an 11-year-old trying to sound academic. It was not something I could realistically use for professional or academic work.
Had that been the end of the story, I probably would not have bothered leaving a review. Plenty of AI tools overpromise and underdeliver.
The real issue was what happened when I tried to cancel.
After testing the software, I decided it was not fit for purpose and attempted to cancel immediately. The cancellation process led me to believe my subscription had been successfully cancelled. After following the cancellation steps, I was presented with upgrade options again, which strongly suggested that I no longer had an active subscription.
I therefore stopped using the service completely and did not log in again.
Over a month later, I checked my bank statements and discovered that weekly payments were still being taken. It turns out there were additional steps required to fully cancel the subscription. In my opinion, the cancellation process is intentionally designed in a way that is confusing and misleading, making it easy for customers to believe they have cancelled when they have not so they can continue to revieve their subscription fees. I would be intersted to know how many subscribers actually actively use the software, or are just in the same predicerment i was, as i cant see how this tool could be useful to anyone with free AI models such as Gemini or ChatGPT available. Albeit they wont pass an AI detection test, but neither will StealthGPT!
When I contacted customer support, I explained that I was happy to pay for the initial week when I tested the software. I simply asked whether the subsequent payments could be refunded because I genuinely believed I had cancelled and had not used the service since.
My concerns were never properly addressed.
Instead, I received a generic response stating that I was outside the refund window. When I explained again that the issue was the misleading cancellation process, not the quality of the product, my concerns were ignored and I was sent a link to the Terms of Service. Nowhere in the terms of service mentions a 'refund window'. After raising the issue again, I received no response at all.
My overall impression is that the company is far more focused on retaining subscription revenue than on delivering a quality product or providing good customer service. The Humanizer feature was ineffective, the cancellation process was confusing, and customer support showed no interest in engaging with the substance of my complaint.
Based on my experience, this feels like the sort of business that survives not because customers are impressed by the service, but because people are unintentionally left subscribed after believing they have cancelled. Whether intentional or not, that was certainly my experience.
My advice is simple: avoid this service. There are far better AI tools available, and if you do decide to sign up, monitor your bank statements carefully and obtain written confirmation if you attempt to cancel.
I would not recommend StealthGPT to anyone.

Best humanizer I've tried so far
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?

Denied Refund
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.

Hi Josiah,
Thanks for the feedback on the quality of StealthGPT! We're glad that it largely met your needs.
Our subscription model is billed based on continued access to StealthGPT rather than usage. As such, our team was unable to provide a refund per our TOS agreed to at purchase.
A member from our team will be reaching out shortly.
We appreciate the feedback!
