The voice
that runs
your Mac

Say it once and Justyne does it: the WhatsApp, the file, the groceries, the browser, the poster, the agent job. She answers out loud in about a second, sees your screen, and acts on the Mac in front of you.

Built to act,
not to chat

A chat window gives you text. Justyne gives you the morning back. Every capability below is something she does on the Mac in front of you, and each one says where it stops to ask.

Messages and files

Finds the file, sends it by name

"Send Priya the launch deck on WhatsApp." She finds the file anywhere on your Mac from how you describe it, opens the right chat in WhatsApp or Telegram and sends it. When two files match she shows you a numbered list and you say which one.

Your day

Briefs you when you ask, where you are

"Brief me at five." At five she sends a short summary of the day to your phone and your own WhatsApp: what she sent, what she ran, what finished and what is still waiting on you. Connect Google Calendar and she reads the schedule out loud too.

The browser

Drives the Chrome you are already signed into

No second browser, no logging in again. She searches, plays the video, fills the grocery cart on Blinkit, Zepto or Instamart, and finds food on Swiggy or Zomato, in your own tabs. Paying and deleting always wait for your yes.

Making things

Posters, decks and sketches from a sentence

A poster or a deck built from one sentence, a sketch drawn right on your screen to explain something, and a beat when you want music. On hard questions she thinks deeply first and draws the answer where you are looking.

Agents

Hands the job to one of your agents and watches it

Say what you want done. She hands it to your Claude, Codex or Grok agent, which works on it in the background while you keep talking to her, and tells you out loud when it is done. Several agents can work side by side, and the orb shows each one.

## Priya Nair client, Ondo Coffee- Prefers WhatsApp over mail, replies fast- Launch deck due Tue 14 Sep, noon- Palette: the brand book, never the old teal ## Ganesh Printers- 300 gsm agreed Fri 10 Sep (never answer money without me) ## Dad- Call on Tuesdays after seven
Tuesday, 8:52

Thirty-two seconds,
six things done

Her words on the left. What actually happened on the Mac, on the right.

TranscriptListening

08:52:10You: Morning. What is waiting on me?

08:52:11Justyne: Three things, ma'am. Priya wants the deck by noon, the printer needs an answer on the paper stock, and your two o'clock moved to three.

08:52:24You: Tell Priya it is coming, build the deck from yesterday's brief, and block me till noon.

08:52:26Justyne: Priya has the note. The deck is building from the brief, nine slides in your palette, and your morning is blocked. Shall I answer the printer with the 300 gsm we agreed on Friday?

08:52:41You: Yes. And remind me to call Dad tonight.

08:52:42Justyne: Sent, and I will remind you at seven. The deck will be ready in about two minutes.

Three layers, one voice

Hears now, thinks with Claude,
acts with real hands

Hears you in under a second

One live socket: she listens and speaks natively and can act mid-sentence. Interrupt her, change your mind, keep talking, and she stops and follows.

Gemini Live · barge-in · wake word

Thinks deeply when it matters

Quick things get a quick answer. Maths, errors on your screen and real decisions go to a thinking model first, and she tells you she is on it while it works.

Your Gemini key · no extra account

Actually does the thing

Real mouse and keyboard, AppleScript, your own Chrome. "Send Priya the deck with the analysis" finds her, attaches both and sends, after you say yes.

Accessibility · Screen · Automation
Reach

Works with what is
already on your Mac

Four ways she reaches a tool: her own, an MCP server, your signed-in Chrome, or an app on the machine. The Connections page shows what is actually ready right now, never a capability she cannot back.

Names are their owners' trademarks. Justyne drives these through their own apps, sites and published MCP servers on your own accounts; she is not affiliated with any of them.

Make her yours

Her name, her voice,
how she speaks to you

Justyne is a starting point. Eight welcome cards on first run decide who she is, and every answer lands in plain files you can change later by hand.

A name and a form of address

Justyne, Friday, anything you like. Sir, ma'am, your first name, or none of that.

Eight voices, eight languages

English, Hindi, Hinglish, Kannada, Tamil, Telugu, Marathi and Bengali, with a voice you pick by listening.

A day she understands

Designer, founder, developer, marketer, student, or describe your own. It changes what she reaches for first.

A tone

Composed butler, sharp friend, or the fewest words that do the job.

Your Mac. Your account.
She ships connected to nothing

Justyne runs on your machine, on your own Gemini key and your own logins. There is no Justyne cloud, no account to create, no server that ever sees what you said.

Your keys, your bill

Her voice runs on your own Gemini key, free to start. Her agents run on the Claude, Codex or Grok app already on your Mac, on the login you already have. Nothing is resold through us.

Your chats stay on your Mac

Conversations, agents and settings live in a data folder on your own machine. Delete it and she remembers nothing.

Keys stay in a file on your disk

Your Gemini key and any other keys are stored on your Mac and are never sent to us.

Analytics are off unless you say so

Anonymous usage analytics stay off until you turn them on in Settings. Never a transcript, a message, a screen or a key.

# What leaves your Mac
voice     = "Gemini, on your key"
agents    = "Claude, Codex or Grok, on your login"
errands   = "the sites you ask her to use"
analytics = "off unless you turn it on"
our_servers = "none"

The whole list. The privacy page has the detail.

What you bring

One key for her voice,
your agents for the rest

Both are your own accounts, and your data stays yours.

Recommended

A Gemini key

Her ears, voice and eyes, free to start

  • Free from Google AI Studio, pasted once in Settings
  • Live, spoken answers in about a second
  • Sees your screen when you ask her to look

Your agents

Optional, for the bigger jobs

  • Claude, Codex or Grok, the app you already use
  • Your existing login, no new account or API bill
  • Several agents can work side by side

The Gemini key is the only thing you need to start.

What voice-first means

Dictation types. Chat answers.

Categories, not products. Every tool here is good at its own job; this is about what happens after you stop speaking.

What is it about

Questions

Before you download

Is it free?
Justyne is free. What you bring is a Gemini key for her live voice, free to start at Google AI Studio. Her agents run on the Claude, Codex or Grok app you already use, on your own accounts.
Do I need to pay for an API?
No. Her voice runs on a Gemini key that is free to start, and her agents use the Claude, Codex or Grok login already on your Mac.
What can she do without asking me?
Read, look, draft, prepare. Sending a message, sending mail, and anything destructive in the browser waits for your yes. The night shift drafts replies into Drafts and never sends until you say "approve all" in the morning.
Why Chrome?
She drives the browser you are already signed into (Gmail, Drive, WhatsApp Web, Pinterest) through Chrome's own scripting, so there is no second login and nothing to sync. Safari and Firefox do not expose the same control.
Which permissions does she need?
Four, all granted from the welcome cards with a link straight to the right pane: Microphone (to hear you), Accessibility (real mouse and keyboard), Screen Recording (to look at the screen when you ask), and Automation (to talk to Chrome, Terminal and Keynote). What each one is for
Does anything leave my Mac?
Your voice goes to Gemini Live on your own key, and her agents use the Claude, Codex or Grok login already on your Mac. Nothing goes to us. Anonymous usage analytics are off unless you turn them on. The full privacy page
How do updates arrive?
On their own. The app checks a signed release feed on launch and installs new versions in the background; every build is published on GitHub Releases, where you can also download any version by hand.

Your Mac, alive

Give her your voice and watch the work start.
