Download, drag,
answer the cards
A signed, notarized Mac app with everything inside. No terminal, no build step. Five minutes from download to the first thing she does for you.
Built for Apple Silicon (M1 and newer). Intel Macs are not supported yet.
Three steps
Open the disk image
Double-click Justyne.dmg. A window opens with Justyne and an Applications shortcut.
Drag, then open
Drag Justyne onto Applications and double-click her there. She starts her backend and opens the welcome cards.
Answer the welcome cards
Allow the microphone, screen and Mac control she asks for, then paste your Gemini key in Settings, Voice. Say "Hey Jarvis" and she is listening.
One key, free to start
Her ears and mouth are a Gemini Live session on your own key. Paste it once in Settings, Voice, and she remembers it on your Mac.
Gemini API key
Free from Google AI Studio. It powers the live conversation: listening, answering out loud and looking at your screen when you ask.
- Stored on your Mac, never sent to us
- Free tier to start
Your agents
Bigger jobs go to agents that run on the Claude, Codex or Grok app already on your Mac, on the login you already have.
- Optional
- No new accounts or API bills
Four switches, each with a reason
The card opens the exact System Settings pane for each one and tells you when it is granted. Nothing is requested that she does not use.
Microphone
To hear you. Audio goes to the live socket while she is awake and nowhere while she sleeps.
Accessibility
Real mouse and keyboard, and answering a permission prompt in a Terminal window with a keystroke when you say yes.
Screen Recording
One downscaled screenshot when you ask her to look. Never on a timer, never saved, never sent anywhere but the model answering that one question.
Automation
AppleScript to Chrome, Terminal, Keynote and the Adobe apps. macOS asks the first time she reaches each app.
