## FAQ

### Where does this Czech content actually get used?

Typically here: Delivered as brief-driven copy decks and docs under tight deadlines, where the client weighs the work against the premium human rate they paid for it. SupWriter humanizes it to survive wherever that path runs into a detector.

### What gives away AI-written Czech?

Concrete tells do. A common one: Verbal aspect misuse. SupWriter watches for these and rewrites around them.

### How does SupWriter make Czech read natively?

By restoring what AI omits. Real Czech carries texture machines skip, such as: Particles 'no', 'pry', 'vzdyt', 'ze jo'. SupWriter puts that back.

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

Czech is written in Latin alphabet with diacritics and belongs to the Slavic (West Slavic) family — a combination English-trained models see far less of. Mid-resource, so detectors lower confidence on Czech; the split between literary spisovna and common obecna cestina confuses register-based signals.

### Is AI-generated Czech usually obvious?

Czech is mid-resource, so output tends to fixed literary standard, missing the common colloquial forms natives use. Either way, Czech readers spot the seams — which is what SupWriter smooths over.
