## FAQ

### Will humanized Croatian still pass GPTZero after I edit it?

Light edits are fine. SupWriter rebuilds sentence rhythm and word choice to match natural Croatian; keep that flow and GPTZero keeps reading it as human. Re-pasting raw AI text is what reintroduces risk.

### Does GPTZero even work on Croatian text?

Only partly. GPTZero officially supports five languages, with English as its primary benchmark target. Its published accuracy figures come from English datasets, and detection quality in the four secondary languages lags behind, particularly on informal or dialect-heavy writing. Closeness to Serbian and Bosnian makes identification unreliable, so detectors may mislabel Croatian or default low.

### Why does AI-generated Croatian sometimes slip past GPTZero on its own?

Croatian is mid-resource within BCS, so output is fluent but sometimes leaks Serbian-leaning vocabulary purists reject. That is why Croatian 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 Croatian reading like a native wrote it?

Yes. SupWriter rewrites against Croatian's own patterns, not a translation of English ones, and it targets the tells that expose AI — like this one: Ijekavian reflexes required ('mlijeko', 'vrijeme'). Your meaning stays intact.

### Can GPTZero reliably tell my Croatian writing from AI?

Its confidence drops off outside English. GPTZero scores perplexity, burstiness, and five other proprietary signals to produce sentence-level AI probability highlights. Closeness to Serbian and Bosnian makes identification unreliable, so detectors may mislabel Croatian or default low. SupWriter widens that margin so your Croatian reads clearly human.
