Partway
Voice control for macOS from tostechbr that acts partway through your sentence: it asks Jev about every word and gets typed decisions back in about 200 ms, so Notes can open before you finish saying the command. It needs a Jev API key and Apple Silicon.

Highlights
- README: it asks Jev, TypeSafe's System One model, about every word and gets typed decisions and probabilities, not text, in about 200 ms.
- Replay demo: with "abre as notas e digita bom dia", Notes opened 0.88 s before the last word; the bar is a real --text run.
- It opens apps and sites, searches in the front browser, presses ⌘N, and types text; commands chain, as in "abre o terminal e digita ls".
- Install is a macOS arm64 .dmg; the app is not notarized yet, so the first open needs System Settings → Privacy & Security → Open Anyway.
- Requires Apple Silicon, macOS 14+ and a Jev API key from console.typesafe.ai; typing and ⌘N need Accessibility permission, and ⏸ or ⌥Space pauses.
Watch out
README reviewed 2026-10-17 and truncated at the end of the trigger-phrase table, so the closing sections were not in the digest. The 200 ms round trip, the 0.88 s head start, and every command are the author's own replays on one Apple Silicon machine, not a benchmark, and the release is not notarized.
Questions about this entry
Short answers drawn from the linked project or page.
A macOS menu-bar app from tostechbr that acts on spoken commands partway through the sentence, asking Jev about every word so it can begin before you finish speaking.
It sends what you say to Jev, TypeSafe's System One model, and receives typed decisions with probabilities rather than text, in about 200 ms per the README, which is what lets it act mid-sentence.
The README shows English and Portuguese commands: opening apps and sites, searching, creating notes with ⌘N, and typing into the front app, with chained examples like "abre o terminal e digita ls". Any further languages are cut off from the capture.
Download partway-macos-arm64.dmg, or the zip, from Releases, drag it to Applications, then allow it via System Settings → Privacy & Security → Open Anyway because it is not notarized yet.
Apple Silicon, macOS 14 or later, microphone and speech-recognition permission, a Jev API key from console.typesafe.ai, and Accessibility permission for typing and ⌘N. The README says it was tested on macOS 26.
The README does not publish pricing; every utterance is judged by Jev, a hosted API, so a key and an account are required. The captured text shows no free tier or offline mode.
It drives apps, sites, searches, ⌘N, and typing rather than arbitrary scripting; the mic is off while paused, the dmg is not notarized, and the README excerpt was truncated before any limitations section.
