## FAQ

### Does Undetectable AI even work on Japanese text?

Only partly. Undetectable AI claims essay support in 20 languages and translation into 36, though those numbers describe its writing tools more than its detection. Because its checks piggyback on English-centric third-party detectors, composite scores on non-English text inherit each underlying tool's blind spots. The spaceless three-script mix defeats English-tuned boundary heuristics, so detectors frequently skip Japanese or default to low confidence.

### Why does AI-generated Japanese sometimes slip past Undetectable AI on its own?

Japanese is high-resource, so output is fluent but keigo consistency and particle nuance often slip, which natives catch. That is why Japanese output can read stilted yet still confuse an English-first detector — but "sometimes" is not "reliably," which is where deliberate humanizing comes in.

### Will SupWriter keep my Japanese reading like a native wrote it?

Yes. SupWriter rewrites against Japanese's own patterns, not a translation of English ones, and it targets the tells that expose AI — like this one: Keigo levels (sonkeigo/kenjougo/teineigo) mixed inconsistently. Your meaning stays intact.

### Can Undetectable AI reliably tell my Japanese writing from AI?

Its confidence drops off outside English. Undetectable AI aggregates verdicts from several third-party detectors into a single composite score rather than running one proprietary model. The spaceless three-script mix defeats English-tuned boundary heuristics, so detectors frequently skip Japanese or default to low confidence. SupWriter widens that margin so your Japanese reads clearly human.

### 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. Undetectable AI, for its part, claims essay support in 20 languages and translation into 36, though those numbers describe its writing tools more than its detection, so its published benchmarks say little about Japanese.
