## FAQ

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

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

### Does Turnitin even work on Portuguese text?

Only partly. Turnitin runs AI detection in English plus a small set of additional languages such as Spanish and Japanese, a fraction of its plagiarism-check coverage. Outside English its model grows noticeably more conservative, and institutions report ESL submissions being both under-detected and unfairly flagged more often than native-English work. 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 Turnitin 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 Turnitin reliably tell my Portuguese writing from AI?

Its confidence drops off outside English. Turnitin analyzes sentence structure, perplexity, and linguistic features across a submission and assigns a document-level AI percentage tuned for conservative flagging. 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.
