It started with one prompt box
A black page, a prompt, a response. We launched StealthGPT with a single idea: AI writing that reads like a person wrote it.

About us
Before StealthGPT, there was no such thing as an AI humanizer.
In early 2023, Jozef Gherman had the idea, spent days reverse-engineering an AI detector until every response came back human, and launched the first tool built to make AI writing read like a person wrote it. That created the industry, the genre and the niche. We've led it ever since. Today StealthGPT is a bootstrapped company trusted by over 1.5 million users, and we're still the team setting the pace.
Our story
Staying undetectable since 2023
May 2023
Stealth Bypass
We rebuilt the app from scratch. You could paste any AI text and rewrite it past the detectors, backed by a money-back guarantee.

The humanizer takes shape
Detectors like Turnitin and GPTZero kept improving, and so did we. StealthGPT became a full AI bypasser and humanizer.

Privacy first, and a free detector
A full redesign, a new paper-plane mark, and a free AI detector so anyone could check their text before submitting it.

The original
We built a writer that learns your style, with citations, auto-complete and text styles, so the output sounds like you and not just like a human.

Today
The AI Humanizer that actually works
We work with ChatGPT, Claude and Gemini, and we're tested against every major detector. Millions of writers use StealthGPT, and we're still improving it.
