## FAQ

### What gives away AI-written Spanish?

Concrete tells do. A common one: Explicit subject pronouns Spanish normally omits. SupWriter watches for these and rewrites around them.

### How does SupWriter make Spanish read natively?

By restoring what AI omits. Real Spanish carries texture machines skip, such as: Regional markers (voseo 'vos tenes', 'che', 'orale', 'vale'). SupWriter puts that back.

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

Spanish is written in Latin alphabet with diacritics and belongs to the Romance (Ibero-Romance) family — a combination English-trained models see far less of. As a high-resource language, detectors attempt Spanish and flag it, but with more low-confidence hedging than English; formal academic Spanish trips false positives.

### Is AI-generated Spanish usually obvious?

LLMs produce fluent Spanish from abundant data, so AI Spanish is fairly detectable but far weaker on regional voseo and dialect than on neutral Latin American register. Either way, Spanish readers spot the seams — which is what SupWriter smooths over.

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

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