StealthGPT

StealthGPT is a text humanizer and AI writing tool marketed to make AI generated content pass AI detectors. Users paste text and the tool rewrites it at the sentence level, and the vendor claims a high bypass rate against detectors such as Pangram, GPTZero and Turnitin. It also says humanization strips the invisible watermarks that some AI models embed in their output. The tool is sold openly as detector evasion, and the site sets out no usage restriction on how the output is used. Beyond the core humanizer it offers long form content generation, a lighter mode that removes stock phrases and em dashes while keeping the draft close to the original, and a Stealth Agent workflow that researches the web, drafts and humanizes in one flow. A Chrome extension types text into any field with human like keystrokes. Integrations include Zapier, a WordPress plugin, an n8n node and use inside Claude and Cursor through MCP, backed by an API. Enterprise plans accept up to 20,000 words per humanization. The interface supports several languages including Spanish, French, German and Chinese. Regular plan prices are not shown on the home page. The site advertises a $1 introductory trial offer for new users.
