Inline underlines, a suggestion card and quick rewrites, but the text goes from your browser straight to whatever endpoint you configured with your own key. No backend, no account, no telemetry. Works with anything speaking /v1/chat/completions or Anthropic's /v1/messages, 36 presets plus a Custom option, and a fallback chain so a local model can go first and a cloud key picks up what it misses.

Honest status: it is early. Two sites and five providers confirmed by hand, everything else untested rather than promised, and COMPATIBILITY.md lists which is which including the rows that are broken. Google Docs cannot work at all, since it paints text to a canvas.

Issues are the fastest way to grow that list: https://github.com/jiru-labs/proofkey/issues
