## FAQ

### Does GPTZero even work on Spanish 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. As a high-resource language, detectors attempt Spanish and flag it, but with more low-confidence hedging than English; formal academic Spanish trips false positives.

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

LLMs produce fluent Spanish from abundant data, so AI Spanish is fairly detectable but far weaker on regional voseo and dialect than on neutral Latin American register. That is why Spanish 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 Spanish reading like a native wrote it?

Yes. SupWriter rewrites against Spanish's own patterns, not a translation of English ones, and it targets the tells that expose AI — like this one: Subjunctive triggers applied by rule instead of feel. Your meaning stays intact.

### Can GPTZero reliably tell my Spanish 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. As a high-resource language, detectors attempt Spanish and flag it, but with more low-confidence hedging than English; formal academic Spanish trips false positives. SupWriter widens that margin so your Spanish reads clearly human.

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

Spanish is written in Latin alphabet with diacritics and belongs to the Romance (Ibero-Romance) family — a combination English-trained models see far less of. GPTZero, for its part, officially supports five languages, with English as its primary benchmark target, so its published benchmarks say little about Spanish.
