What leaves my Mac when I speak a command?

Only the transcript plus small routing context such as frontmost app and installed names goes to Jev. Audio transcription itself stays on-device with SpeechAnalyzer, Apple speech, or Whisper selected in Hearing settings.

What does Jev decide versus local code?

The local parser takes deterministic commands and slot extraction takes URLs, queries, and percentages. Jev only returns typed action and target choices, never free text, and low-confidence calls ask for confirmation.

How does it click the right control in another app?

It observes the Accessibility tree, picks an element, acts, then re-observes and verifies. Thin Chromium trees can fall back to Chrome DevTools Protocol, with local OCR and bounded planner fallbacks behind that.

Can it learn new commands, and what is blocked?

When script learning is on, Jev can propose AppleScript or JXA tools that must compile, pass the policy scanner, and pass review before running. Shell, payment, credential, and destructive phrases are blocked by policy with confirmation defaults.

How do I trigger it, and where does transcription run?

Hold Option-Space to speak and release to send, or use toggle mode from Settings. Transcription is on-device: SpeechAnalyzer streaming is the default on macOS 26 when built in, with Whisper and the classic Apple recognizer as alternatives in Settings. Apple streaming needs Swift 6.2 or newer and Xcode 26, and --engine-info reports which engine a binary has.

What seven questions does Jev answer per clause?

action (one of openApp, closeApp, openURL, webSearch, dictate, uiTask, system or none), target_app (installed names up to 254 plus none), system_action, and the nouls mentions_url, refers_to_frontmost, composes and destructive. Arguments such as URLs, queries and percentages are extracted deterministically by SlotExtractor because Jev is decision-only.

How do I install it, and where does the key live?

It doubles as a Homebrew tap: brew tap chris-wozniczek/jev-voice then brew install --cask jev-voice, running brew trust first if Homebrew refuses the third-party tap. From source it is make app and make run. Set the key in the popover Settings, with defaults write com.chriswozniczek.jevvoice typesafeAPIKey, or export TYPESAFE_API_KEY before launching.

About this project

A macOS menu-bar app that turns spoken commands into actions using TypeSafe AI's Jev — a System One model that returns typed decisions with probabilities instead of generated text. v0.9.1 is a public reliability release. Hold ⌥Space to speak and release it to send the command. Toggle mode is available in Settings when you prefer to start and stop listening with a press. Useful links: Design · documentation site. Press ⌥Space, say something, and Jev decides what to do: "open chrome and go to google.com"

Languages: Swift

Highlights

Hold-to-talk plus toggle mode, with app aliases, spoken replies, and optional ask-before-running confirmation.
Keeps mixed commands ordered as local open plus Jev-guided UI work with hard-to-undo confirmation.
Verifies typing by reading the focused field back and falls back to Unicode keyboard entry when needed.
Resolves sites from a bundled registry with overrides and requires confirmation for post, send, and publish.

Watch out

Needs microphone, speech recognition, accessibility, screen recording, and automation permissions; irreversible and browser-submit actions default to confirmation. Copy reviewed against the repository README on 2026-10-04, not from running it.
