What is StealthGPT?
StealthGPT is an AI humanizer that rewrites text from ChatGPT, Claude and Gemini so it reads more naturally and scores as human on AI detectors. Alongside the Humanizer it offers a free AI Detector that gives an instant score without signup, plus Stealth Writer for essays and articles with citations.
The humanizer has two modes: Stealth Lite cleans up AI tells such as em dashes and stock phrases while keeping the draft close to the original, and Super does a full rewrite aimed at bypassing detectors. You can pick a tone (Standard, High School, College, Ph.D.), and the rewrite also strips the invisible watermarks Claude and Gemini put in their text. Stealth Agent researches, drafts, fact-checks and humanizes SEO articles, essays and social posts in one flow.
It fits students, content writers and agencies. Developers get an API, an MCP server, and integrations with Zapier, n8n and WordPress, plus a Chrome extension.
