## FAQ

### Does Grammarly even work on Czech text?

Only partly. Grammarly is English-only for AI detection, despite Grammarly's broader multilingual editing ambitions. There is no non-English mode to evaluate — paste anything but English into it and you get no meaningful AI verdict at all. Mid-resource, so detectors lower confidence on Czech; the split between literary spisovna and common obecna cestina confuses register-based signals.

### Why does AI-generated Czech sometimes slip past Grammarly on its own?

Czech is mid-resource, so output tends to fixed literary standard, missing the common colloquial forms natives use. That is why Czech output can read stilted yet still confuse an English-first detector — but "sometimes" is not "reliably," which is where deliberate humanizing comes in.

### Will SupWriter keep my Czech reading like a native wrote it?

Yes. SupWriter rewrites against Czech's own patterns, not a translation of English ones, and it targets the tells that expose AI — like this one: Literary spisovna where speech uses obecna cestina. Your meaning stays intact.

### Can Grammarly reliably tell my Czech writing from AI?

Its confidence drops off outside English. Grammarly checks whether prose follows word-sequence patterns typical of large language models, layered on top of its grammar-analysis engine. Mid-resource, so detectors lower confidence on Czech; the split between literary spisovna and common obecna cestina confuses register-based signals. SupWriter widens that margin so your Czech reads clearly human.

### What makes Czech harder for detectors than English?

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. Grammarly, for its part, is English-only for AI detection, despite Grammarly's broader multilingual editing ambitions, so its published benchmarks say little about Czech.
