StealthWriter
StealthWriter is an AI text humanizer and detector that rewrites content from ChatGPT, Claude, and Gemini so it reads as naturally human-written. It includes a V2 AI detector, deep scan, sentence-level fine-tuning, and multiple rewrite levels, with a free plan and paid tiers for higher volume.
What is StealthWriter?
StealthWriter is an AI text humanizer and detector that rewrites AI-generated content from tools like ChatGPT, Claude, or Gemini so it reads as naturally human-written. The service takes pasted text and produces clean, natural output in under ten seconds, with a built-in AI detector to verify results before and after humanizing. It offers three core functions: humanize, detect, and improve. The AI Humanizer rewrites text with multiple rewrite levels and sentence-level fine-tuning, so users can adjust specific sentences rather than accepting a wholesale rewrite. The AI Detector includes a V2 scanner with deep scan capability, and the homepage lets users paste text to check whether it is detectable as AI. The platform emphasizes human by design output: it avoids the awkward, error-filled text that generic humanizers produce, generating original rewrites that do not trigger plagiarism detectors. It also supports alternative rewrites, giving users multiple versions of the humanized text to choose from. In August 2026, StealthWriter announced it can remove the Claude watermark from AI-generated text, extending its compatibility beyond ChatGPT and Gemini content. Pricing is transparent: the free plan includes 10 humanizations per day with 1,000 words per input, including the V2 detector and deep scan. Starter costs $20 per month with 50 humanizations per day and 5,000 words per input; Plus costs $50 with 150 per day; Pro costs $100 with 350 per day; and Scale costs $400 with 2,000 per day, with yearly billing available at a discount. The platform states that submitted text is not stored after processing and is not used for training, which matters for users handling sensitive or unpublished content. Contact and support are available by email and phone, and the product positions itself as continuously updated to keep output natural as AI detectors evolve. The platform also provides an API-free, browser-based workflow that works on any device, and its changelog documents ongoing improvements. For users who need to process content in bulk, the higher tiers support hundreds of humanizations per day with larger word limits.
