What is StealthWriter?
StealthWriter is a web tool that takes text produced by AI assistants such as ChatGPT, Claude or Gemini and rewrites it so the phrasing, rhythm and flow read as human-written. It bundles a humanizer with an AI detector, so you can scan a draft before and after rewriting and see which sentences still need work.
In practice you paste up to 5,000 words per input on paid plans (1,000 on the free plan), choose a light, medium or aggressive rewrite level, and get the result back in seconds. The Deep Scan highlights sentences sentence by sentence, and you can click any sentence to choose from alternative rewrites to fine-tune the output to your voice.
