Hey Halo.
The assistant your
Mac
always needed.
Hey Halo is a private AI assistant that lives in your Mac's notch. It finishes your sentences, takes notes on your calls, remembers what you've seen, and speaks up only when it matters. All on your Mac.
Trusted by early users
Proactive
It speaks up, so you don't have to remember.
This is the part that feels most like a Jarvis. Halo keeps a quiet eye on your day and reaches you the moment something needs you: a meeting that just moved, a promise still sitting in your drafts, a build that broke. It finds you in the notch, out loud, or on your phone when you're away.
Quiet by design. It earns every interrupt. Halo notifies and prepares, and never sends, deletes, or buys on its own.
Built for how you work
For every part of your day.
From deep work to daily tasks, Halo fits right into your flow, and does the work across your apps.
3 meetings today. Prep ready for Maya. 2 follow-ups owed.
Can you get me the Q3 numbers?
Of course, I'll send them over by end of day.

Hi! Just circling back, are those still on track?
We can't ship Friday, the importer's half done.
Agreed. Let's move it to v1.1.
Ship date moved to v1.1. Action: Ana to finish importer.
Sarah said she'd send the vendor contract by Thursday.
"Hey Halo, move my 2pm to tomorrow"
Moved "Design review" to tomorrow, 2:00 PM.
Real customer from Acme. Drafted a reply, ready to send.
Not another AI app
It's not a clone. It's a category of its own.
You already know tools that do one of these: dictation, autocomplete, meeting recorders, AI agents. The difference with Halo is that it's all of them at once, on your Mac, and it actually remembers.
See how Halo is different-
Chatbots talk. Halo remembers what you saw, heard, and typed.
-
Dictation apps type. Halo also recalls, drafts, and joins your meetings.
-
Cloud agents send your life to a server. Halo's brain runs on your Mac.
The contract
Powerful AI.
Private by default.
Your screen, your calls, your memory. Processed on your Mac. We couldn't read them if we wanted to.
On-device AI
The brain runs locally
Encrypted
Sync uses AES-GCM
You own it
Your data, your Mac
-
Every captured frame is deleted after a single read.
-
Live audio becomes a transcript and isn't kept. Recordings you start stay on your Mac and auto-delete on your schedule.
-
Memories are written summaries, never images, never screenshots.
-
No telemetry. We don't know how often you launch the app.
Coming soon
One Halo, every device.
Text Halo from your phone, and let it text you the moment something needs you while you're away. The iPhone companion is in beta testing, with Apple Watch next, then Vision Pro and glasses, all with end-to-end encrypted sync between them. Pro and Lifetime supporters fund this work.
