## FAQ

### Will humanized Japanese still pass Surfer after I edit it?

Light edits are fine. SupWriter rebuilds sentence rhythm and word choice to match natural Japanese; keep that flow and Surfer keeps reading it as human. Re-pasting raw AI text is what reintroduces risk.

### Does Surfer SEO even work on Japanese text?

Only partly. Surfer SEO optimizes content in multiple European languages for SEO, but its AI detector is calibrated for English publishing workflows. If its English verdicts already diverge from dedicated detectors, its readings on non-English SEO content deserve even less weight — no multilingual detection benchmarks exist. 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 Surfer 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: Topic 'wa' vs subject 'ga' chosen wrongly. Your meaning stays intact.

### Can Surfer SEO reliably tell my Japanese writing from AI?

Its confidence drops off outside English. Surfer SEO estimates AI likelihood as a sidecar to its SEO content editor, and users report its 99%-human verdicts often contradict specialized detectors. 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.
