## FAQ

### Does QuillBot even work on Czech text?

Only partly. QuillBot supports AI detection in six languages: English, French, Spanish, German, Dutch, and Portuguese. All six supported languages are European and Latin-script; its already-high false-positive tendency worsens on short non-English text, and CJK content is simply out of scope. 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 QuillBot 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 QuillBot reliably tell my Czech writing from AI?

Its confidence drops off outside English. QuillBot leans on the same language models behind its paraphraser to estimate how AI-like a passage reads, with a known tilt toward over-predicting AI. 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. QuillBot, for its part, supports AI detection in six languages: English, French, Spanish, German, Dutch, and Portuguese, so its published benchmarks say little about Czech.
