Hey Jev
A Mac-only voice assistant: say Hey Jev or hold right Option and Jev decides every command in one call for $0.00004 per request, while Whisper transcribes locally, Fish Audio S2.1 Pro speaks replies, and an LLM wakes only for questions.

Highlights
- Every command decision is one Jev (TypeSafe) call at $0.00004 per request per the README; only the text after Hey Jev is sent to TypeSafe.
- Handles open, quit, hide, minimise, switch apps, browser tabs and sites, volume, Spotify playback, dark mode, lock and sleep, plus timers and reminders.
- Dictation is the one feature that sends audio off the Mac: clips go to OpenRouter and OpenAI's gpt-4o-mini-transcribe unless you add your own OpenAI key.
- Whisper (faster-whisper) runs locally and downloads small.en, about 250 MB, on first launch; anything that is not a command goes to Claude Haiku via OpenRouter.
- Setup builds a py2app bundle in alias mode; siri.py runs from the terminal with --wake, --text, and --ui switches, printing the Jev trace per turn.

Copy reviewed against the repo README on 2026-10-15. The $0.00004-per-request figure and the free Fish Audio s2.1-pro-free window (until the end of November 2026) are the README's own claims; the digest metadata shows no license, and the app needs macOS Sequoia or Tahoe plus Microphone, Accessibility, and Automation permissions.
Questions about this entry
Short answers drawn from the linked project or page.
A voice assistant for the Mac: hold right Option or say Hey Jev, speak a command, and it does the thing and answers aloud. It works on macOS Sequoia and Tahoe only, and controls the Mac through AppleScript and the Keychain.
Jev (TypeSafe) makes every command decision in a single call, which the README prices at $0.00004 per request. Only the text of commands after Hey Jev goes to TypeSafe, and an LLM is woken only when Jev decides you asked a question.
Open, quit, hide, minimise or switch apps; open a browser tab or a site like open youtube.com in Brave; Mac and Spotify volume; play, pause, next, previous; dark mode; lock or sleep; timers and reminders; and two actions in one sentence.
A Mac, Python 3 (tested on 3.14), the Spotify desktop app for music commands, and three API keys: TypeSafe, Fish Audio, and OpenRouter. An OpenAI key is optional and sends dictation straight to OpenAI instead of through OpenRouter.
Local Whisper transcribes everything except dictation; between transcribe and stop transcribing, audio uploads to OpenRouter and OpenAI, or straight to OpenAI if you add a key. Vocabulary files are gitignored and keys are stored in the macOS Keychain.
The README says Jev costs $0.00004 per request, Fish Audio's s2.1-pro-free model is free until the end of November 2026, and OpenRouter usage is billed to your account. No license file is shown in the digest metadata.
No; it is Mac-only because it controls the Mac through AppleScript and the Keychain. You can skip building the app and run it from the terminal with .venv/bin/python siri.py, adding --wake, --text, or --ui as needed.
