## FAQ

### Why does AI-generated Vietnamese sometimes slip past Grubby AI 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: Tone-diacritic errors that change meaning. Your meaning stays intact.

### Can Grubby AI reliably tell my Vietnamese writing from AI?

Its confidence drops off outside English. Grubby AI runs transformation passes intended to strip machine-typical phrasing, with effectiveness that shifts from one detector to the next. 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. Grubby AI, for its part, documents little about language coverage and appears tuned for English input, so its published benchmarks say little about Vietnamese.

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

Vietnamese is fully supported — one of 50-plus languages SupWriter handles natively. Feeding it non-English text is an experiment: its rewriting heuristics were shaped by English AI output, and other languages fall outside anything it has demonstrated. SupWriter is built to exploit exactly that weakness.
