StealthGPT

StealthGPT is an AI humanizer that rewrites AI-generated text so it reads like natural human writing and passes AI detectors. Paste a draft from ChatGPT, Claude or Gemini, choose Stealth Lite to clean up AI tells such as stock phrases and em dashes, or Super for a full rewrite built for AI detection bypass. Humanization also strips the invisible watermarks Claude and Gemini embed in their output.

Alongside the humanizer, StealthGPT includes a free AI detector that returns a human score with no signup, Stealth Writer for essays with formatted citations, Stealth Agent for researching, drafting and fact-checking long articles, Chat with PDF, Photo to Answers, an SEO Writer, and tone options from Standard to Ph.D.

StealthGPT runs on the web, as a Chrome extension with human-like auto-typing, as an iOS app, and through an API and MCP server that plug into Claude, Cursor, n8n, Zapier and WordPress. Enterprise plans humanize up to 20,000 words in a single run.

StealthGPT started in 2023 as the world's first AI humanizer. It says it has more than 1.5 million users, has humanized 9.4 million+ documents, and reports a 99% bypass rate. Start for $1: a 3-day trial on Pro or Max, then $29.99 per month.
