In February, Joseph bought the domain stealthgpt.ai for $150, watched YouTube tutorials, and had his first paying customers by March. Fifteen months later, the AI text-humanizer was doing $190,000 in monthly recurring revenue. He barely knew how to code when he started.

The business, StealthGPT, generates AI-written text that passes as human-written, or rewrites text from ChatGPT, Claude, and Gemini to make it undetectable.

A TikTok video appeared in his feed about GPTZero, a tool claiming 99% accuracy at detecting AI text. He started reverse-engineering it.
