## FAQ

### Where does this Japanese content actually get used?

Typically here: Delivered as brief-driven copy decks and docs under tight deadlines, where the client weighs the work against the premium human rate they paid for it. SupWriter humanizes it to survive wherever that path runs into a detector.

### What gives away AI-written Japanese?

Concrete tells do. A common one: Pronouns (watashi/anata) Japanese normally omits. SupWriter watches for these and rewrites around them.

### How does SupWriter make Japanese read natively?

By restoring what AI omits. Real Japanese carries texture machines skip, such as: Sentence-final particles ne/yo/na/wa. SupWriter puts that back.

### Why is Japanese harder to get past AI detectors?

Japanese is written in Mixed kanji, hiragana, and katakana and belongs to the Japonic family — a combination English-trained models see far less of. The spaceless three-script mix defeats English-tuned boundary heuristics, so detectors frequently skip Japanese or default to low confidence.

### Is AI-generated Japanese usually obvious?

Japanese is high-resource, so output is fluent but keigo consistency and particle nuance often slip, which natives catch. Either way, Japanese readers spot the seams — which is what SupWriter smooths over.
