StealthWriter
Rewrites AI-generated text so it reads naturally human, with a built-in AI detector to check before and after
StealthWriter takes AI-generated drafts from tools like ChatGPT, Claude, or Gemini and rewrites them with natural human phrasing, rhythm, and flow. It includes a built-in AI Detector so you can scan text before and after humanizing, a Deep Scan mode with sentence-by-sentence, color-coded highlights showing what still needs work, and Alternative Rewrites that let you click any sentence to pick from multiple variations to fine-tune the output to your own voice. Text submitted is not stored after processing.

FAQ
Is StealthWriter free to use?
Yes, the Free plan includes 10 humanizations and 10 AI scans per day with a 1,000-word input limit, no credit card required. Paid plans start at $20/mo for higher daily limits and a 5,000-word input cap.
Is my text stored when I use StealthWriter?
No. According to StealthWriter, text submitted for humanizing or scanning is not stored after processing, not shared with third parties, and not used for training.
How is StealthWriter different from other AI humanizers?
It pairs the humanizer with a built-in AI detector and a Deep Scan mode that highlights specific sentences still reading as AI-generated, plus Alternative Rewrites so you can fine-tune individual sentences rather than accepting one full rewrite.
Where it holds up
- Free plan needs no credit card and includes both the humanizer and detector, not a stripped-down trial
- Deep Scan highlights weak sentences individually instead of just giving one overall score
- Alternative Rewrites let you pick between multiple phrasings per sentence rather than accepting one full rewrite
Where it falls short
- Daily usage caps (not monthly word pools) mean heavy single-day use can hit the limit even on paid plans
- Input length is capped at 1,000 words on the Free plan, too short for a full article or essay
- Jump from Starter ($20/mo) to Plus ($50/mo) to Pro ($100/mo) is steep for anyone just above the lowest tier's daily limit
