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.
