StealthWriter is an AI humanizer. It takes text from ChatGPT, Claude or Gemini and rewrites it so detection tools classify it as human-written, at light, medium or aggressive intensity, with Deep Scan analysing sentence by sentence and alternative rewrites offered per sentence. A bundled detector checks whether the output passes.
It is worth being precise about what that is. This is not an editing tool that happens to improve AI prose; the product is measured against detection classifiers, and the bundled detector exists so you can confirm the evasion worked. The first audience the site names is students, and submitting work rewritten to defeat detection is academic misconduct at essentially every institution.
AiVantage prices it free, then $20, $50, $100 and $400 a month. Beyond the ethics there is a practical problem: detector evasion is an arms race, so what passes today fails after the next detector update and the rewriting itself degrades precision, flattening exactly the specific phrasing that made a point land. For marketers and bloggers rewriting their own drafts the tool is unremarkable; the framing is the problem.
