## FAQ

### What makes Japanese harder for detectors than English?

Japanese is written in Mixed kanji, hiragana, and katakana and belongs to the Japonic family — a combination English-trained models see far less of. Stealthwriter, for its part, handles only English, Spanish, and French — one of the narrowest language ranges in this space, so its published benchmarks say little about Japanese.

### Does SupWriter actually support Japanese, or just English?

Japanese is fully supported — one of 50-plus languages SupWriter handles natively. Even in Spanish and French its rewrites introduce more grammar errors than in English, and its checker offers no signal at all for the world's other languages. SupWriter is built to exploit exactly that weakness.

### How fast can I humanize Japanese content to beat Stealthwriter?

Most Japanese documents process in under 25 seconds, and the output is tuned to clear Stealthwriter on the first pass while keeping your original meaning intact.

### Is it risky to run raw Japanese AI text through Stealthwriter?

That is the bigger risk, since Stealthwriter ships a built-in checker that mirrors the patterns its Ghost Mini and Ghost Pro rewriting models target. Humanizing first means the text no longer carries the even, low-variation fingerprint those signals look for.

### What does SupWriter actually change in my Japanese text?

It restores what AI flattens. Natural Japanese shows markers machines skip, like this: Sentence-final particles ne/yo/na/wa. SupWriter reintroduces that texture so the writing reads authentically Japanese.
