## FAQ

### Will humanized Portuguese still pass Copyleaks after I edit it?

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

### Does Copyleaks even work on Portuguese text?

Only partly. Copyleaks officially supports AI detection in 30+ languages, among the broadest coverage of any enterprise detector. 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. Detectors handle Portuguese but rarely tell European from Brazilian norms, and formal Brazilian academic prose draws false positives.

### Why does AI-generated Portuguese sometimes slip past Copyleaks on its own?

High-resource via Brazilian data, so AI Portuguese is fluent and detectable but skews Brazilian even when European is requested. That is why Portuguese 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 Portuguese reading like a native wrote it?

Yes. SupWriter rewrites against Portuguese's own patterns, not a translation of English ones, and it targets the tells that expose AI — like this one: Future subjunctive underused where natives deploy it naturally. Your meaning stays intact.

### Can Copyleaks reliably tell my Portuguese 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. Detectors handle Portuguese but rarely tell European from Brazilian norms, and formal Brazilian academic prose draws false positives. SupWriter widens that margin so your Portuguese reads clearly human.
