## FAQ

### 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 Job seekers and career changers actually work — passing detectors while reading like a native wrote it.

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

A cover letter that sounds mass-generated defeats its only purpose — proving genuine interest — and quietly moves the application to the rejection pile. Native-quality Portuguese that clears detection is the way around that.

### Who will notice if this reads AI-written?

Hiring managers who have read a thousand identical openings skim for one genuinely specific sentence — and its absence is the AI tell they act on. Human Portuguese readers are even less forgiving of unnatural phrasing.
