## FAQ

### Will the Czech still sound right for this kind of writing?

Yes. The register — first-person professional storytelling — insight-led, lightly personal, and free of the formulaic cadence LinkedIn users now mock — is preserved, and SupWriter renders it in idiomatic Czech rather than a stiff translation of English.

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

Typically here: Posted natively into LinkedIn's feed, where the algorithm rewards early engagement and an audience of peers, recruiters, and clients scrolls with growing skepticism. SupWriter humanizes it to survive wherever that path runs into a detector.

### What gives away AI-written Czech?

Concrete tells do. A common one: Numeral-noun agreement. 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: Common-Czech endings (literary '-y' shifting to '-ej'). 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.
