The README opens with

Voice control for macOS that acts partway through your sentence.

Replay of a real --text run, drawn as the bar: Notes opened 0.88 s before the last word.

Say "abre as notas e digita bom dia" and Notes is already open while you are still saying "digita".

It asks Jev, TypeSafe's System One model, about every word you say. Jev answers with typed decisions and probabilities, not text, in about 200 ms, so the app can act mid-sentence and wait only when it has to.
