## FAQ

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

Its confidence drops off outside English. Copyleaks combines AI-text classification with plagiarism matching in a single enterprise scan, flagging statistical fingerprints of LLM output at the passage level. 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. Copyleaks, for its part, officially supports AI detection in 30+ languages, among the broadest coverage of any enterprise detector, 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 with genuine multilingual training, its non-English precision trails its English results, and false-positive behavior in smaller languages has not been independently audited. SupWriter is built to exploit exactly that weakness.

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

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

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

That is the bigger risk, since Copyleaks combines AI-text classification with plagiarism matching in a single enterprise scan, flagging statistical fingerprints of LLM output at the passage level. Humanizing first means the text no longer carries the even, low-variation fingerprint those signals look for.
