Rewrites AI-generated text to slip past AI detectors
StealthGPT rephrases machine-written text so that classifiers such as Turnitin and GPTZero score it as human-authored, and wraps that core in its own detector, an essay writer with citations, PDF chat and SEO drafting. Access runs through the web app, a Chrome extension, a documented REST API, an MCP server, and connectors for n8n, Zapier and WordPress. It is operated by XYZ AI Inc., which has sold the humanizer since 2023 and now also markets watermark removal for Claude and Gemini output.
Plans are advertised as a daily rate billed as a subscription, capped on requests per day and words per request.
Use tool ↗The only thing here that competitors do not match is the developer surface — REST API, MCP server and n8n node — so this is the humanizer you pick if you are automating a content pipeline, not the one you pick to write an essay. Everything it sells is a bet on an arms race the detector vendors are also funding.
Watch out: Any measured pass rate is a snapshot — detector vendors retrain, and a plan bought on this month's results can stop working next month with no refund path.
