## FAQ

### Why is Portuguese harder to get past AI detectors?

Portuguese is written in Latin alphabet with diacritics and belongs to the Romance (Ibero-Romance) family — a combination English-trained models see far less of. Detectors handle Portuguese but rarely tell European from Brazilian norms, and formal Brazilian academic prose draws false positives.

### Is AI-generated Portuguese usually obvious?

High-resource via Brazilian data, so AI Portuguese is fluent and detectable but skews Brazilian even when European is requested. Either way, Portuguese readers spot the seams — which is what SupWriter smooths over.

### How fast is it, and does it keep my meaning?

Most Portuguese documents finish in under 25 seconds with your meaning intact — SupWriter changes how the Portuguese is phrased, not what it says.

### Can SupWriter humanize Portuguese content for this audience?

Yes. SupWriter handles Portuguese natively and tunes the output to how Business professionals, executives, and sales teams actually work — passing detectors while reading like a native wrote it.

### What happens if my Portuguese content is flagged as AI?

An email that reads machine-written erodes the trust a deal depends on — prospects stop replying, and a proposal that feels templated loses to a competitor who sounded human. Native-quality Portuguese that clears detection is the way around that.
