Update 23/04/2026: V2 scanner added — now significantly more accurate + Improved readability on 5.1 model
New features, improvements, and fixes shipping to StealthWriter.
The 5.1 humanizer now supports major world languages — including German, Spanish, Portuguese, French, Italian, Dutch, Chinese, Japanese, and more. Paste text in your language and get natural, undetectable output without switching to English first.
Resolved an edge case where longer inputs could be truncated before a sentence was fully rewritten. Your output now consistently finishes every sentence it starts.
Fixed an issue where some sentences weren't being highlighted after humanization. Every rewritten sentence is now properly mapped and visible in the UI.
We tuned the 5.1 humanizer to produce cleaner, more natural prose — fewer awkward phrasings, better flow, and less friction for your readers, with the same bypass strength.
Our AI detector has been upgraded to V2 — significantly more accurate at identifying AI-written text and more consistent across different writing styles and lengths. Expect fewer false positives and sharper confidence scores.
