## FAQ

### Why does AI-generated Bulgarian sometimes slip past Surfer on its own?

Bulgarian is lower-mid resource, so output can miss the renarrative mood and postposed article that mark natural Bulgarian. That is why Bulgarian 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 Bulgarian reading like a native wrote it?

Yes. SupWriter rewrites against Bulgarian's own patterns, not a translation of English ones, and it targets the tells that expose AI — like this one: Verb aspect and the rich tense system. Your meaning stays intact.

### Can Surfer SEO reliably tell my Bulgarian 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. Cyrillic script and lower resource lead detectors to skip Bulgarian or default low; it is sometimes confused with Macedonian or Russian. SupWriter widens that margin so your Bulgarian reads clearly human.

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

Bulgarian is written in Cyrillic alphabet and belongs to the Slavic (South 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 Bulgarian.

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

Bulgarian 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.
