## FAQ

### Does QuillBot even work on Vietnamese 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. Detectors misparse Vietnamese word boundaries and often default to low confidence; diacritic-stripped text breaks language identification.

### Why does AI-generated Vietnamese sometimes slip past QuillBot on its own?

Vietnamese is mid-resource, so output is fluent but tends to flatten tone-word choice and classifier usage. That is why Vietnamese 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 Vietnamese reading like a native wrote it?

Yes. SupWriter rewrites against Vietnamese's own patterns, not a translation of English ones, and it targets the tells that expose AI — like this one: Serial verb constructions rendered stiffly. Your meaning stays intact.

### Can QuillBot reliably tell my Vietnamese 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. Detectors misparse Vietnamese word boundaries and often default to low confidence; diacritic-stripped text breaks language identification. SupWriter widens that margin so your Vietnamese reads clearly human.

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

Vietnamese is written in Latin alphabet with diacritics (chu Quoc ngu) and belongs to the Austroasiatic (Vietic) 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 Vietnamese.
