## FAQ

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

Its confidence drops off outside English. Grubby AI runs transformation passes intended to strip machine-typical phrasing, with effectiveness that shifts from one detector to the next. 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. Grubby AI, for its part, documents little about language coverage and appears tuned for English input, 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. Feeding it non-English text is an experiment: its rewriting heuristics were shaped by English AI output, and other languages fall outside anything it has demonstrated. SupWriter is built to exploit exactly that weakness.

### How fast can I humanize Japanese content to beat Grubby AI?

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

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

That is the bigger risk, since Grubby AI runs transformation passes intended to strip machine-typical phrasing, with effectiveness that shifts from one detector to the next. Humanizing first means the text no longer carries the even, low-variation fingerprint those signals look for.
