| **Proofbird** — a writing assistant for Windows that checks spelling and grammar as you type, in the apps you already use. |
|
|
| The grammar models run **on your own computer**: your text doesn't leave the machine for a grammar check. They're small, |
| fast and open — published here under open licences (Apache-2.0; Spanish CC BY 4.0, matching its base model), with their |
| training data, measured results and known limits on each card. |

| German follows. Every model card has a quick start: one Python file, or one click to run it in Google Colab. |
|
|
| **How they're made:** synthetic errors over Wikipedia and Tatoeba sentences — no learner essays, no non-commercial training |
| data, no user text. Precision first: a missed error is acceptable, a wrong correction is not. |
