What it does

StealthGPT rewrites AI text into humanized text that aims to bypass AI detection. It includes an AI detector that gives an instant human score, a stealth writer for essays with citations, and a Chrome extension. It also removes invisible watermarks from Claude and Gemini through structural rewriting.

StealthGPT is a writing tool that focuses on making AI text read as human. You can paste or generate text, run the humanizer, and then check the human score with the built-in detector. The site says no account is needed for your first scan. It also offers a stealth writer for essays with citations, a Chrome extension, and a Stealth Agent that researches, drafts, and humanizes in one flow. Watermark removal for Claude and Gemini is included through structural rewriting. The site lists an API for programmatic access and an MCP option for Claude, Cursor, and n8n. A WordPress plugin and a Zapier integration are also mentioned. The homepage shows a $1 offer for 3 days for new users, but no full pricing page was found, so plan costs are unclear. Detection tools change often, so test output on your own detector and check the current terms.
