## FAQ

### Is it risky to run raw Spanish AI text through Grammarly?

That is the bigger risk, since Grammarly checks whether prose follows word-sequence patterns typical of large language models, layered on top of its grammar-analysis engine. Humanizing first means the text no longer carries the even, low-variation fingerprint those signals look for.

### What does SupWriter actually change in my Spanish text?

It restores what AI flattens. Natural Spanish shows markers machines skip, like this: Regional markers (voseo 'vos tenes', 'che', 'orale', 'vale'). SupWriter reintroduces that texture so the writing reads authentically Spanish.

### Will humanized Spanish still pass Grammarly after I edit it?

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

### Does Grammarly even work on Spanish text?

Only partly. Grammarly is English-only for AI detection, despite Grammarly's broader multilingual editing ambitions. There is no non-English mode to evaluate — paste anything but English into it and you get no meaningful AI verdict at all. 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 Grammarly 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.
