## FAQ

### Why does AI-generated Czech sometimes slip past Surfer 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: Seven-case declension including the vocative. Your meaning stays intact.

### Can Surfer SEO reliably tell my Czech writing from AI?

Its confidence drops off outside English. Surfer SEO estimates AI likelihood as a sidecar to its SEO content editor, and users report its 99%-human verdicts often contradict specialized detectors. 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. Surfer SEO, for its part, optimizes content in multiple European languages for SEO, but its AI detector is calibrated for English publishing workflows, so its published benchmarks say little about Czech.

### Does SupWriter actually support Czech, or just English?

Czech is fully supported — one of 50-plus languages SupWriter handles natively. If its English verdicts already diverge from dedicated detectors, its readings on non-English SEO content deserve even less weight — no multilingual detection benchmarks exist. SupWriter is built to exploit exactly that weakness.
