Halo · idle
Voice
Press ⌘⇧M or say “Hey Halo” and start talking, anywhere on your Mac. No window to find, no app to open. Halo is already listening.
⌘⇧M · or “Hey Halo”
Autocomplete
Ghost text appears as you type, in any app. Press Tab to take it; keep typing and it quietly steps aside. It writes in your voice, not a robot's.
⇥ to accept · works everywhere you type
Record
One shortcut records any call, then writes it up with speaker names and a clean summary the moment you hang up. The audio never leaves your Mac.
⌘⌃R · transcript, names, summary
Recall
Halo remembers the meaning of what crossed your screen and your calls, never the pictures. Ask in plain words and get the answer, with its sources.
Plain-language search · sources attached
Act
Create the event, draft the reply, look up the contact. Halo uses the tools you already have to finish the job, then shows its work so you stay in control.
Calendar · Mail · Contacts · and more
Automations
Acting on demand is only half of it. Describe a standing job in a sentence, an inbox, a repo, a price, and Halo runs it on your Mac, watching while you work. It pings you when something needs you, and never sends, buys, or deletes without your okay.
Runs on your Mac · notifies, never acts alone
Connected tools
Beyond the built-in integrations, point Halo at any MCP server and it can use those tools too, right where your work already lives. You choose what to add, and it shows its work so you stay in control.

A day with Halo
7:42 am
A short brief each morning: what's coming, who you owe, what slipped yesterday.
11:15 am
Ghost text wherever you type. Tab to take it; keep typing and it gets out of the way.
2:00 pm
One shortcut records any call, then writes it up with speaker names and a summary when you hang up. The recording never leaves your Mac.
6:30 pm
Weeks later, ask in plain words. You get the answer, with its sources.
while you're away
Set a standing job in a sentence: the inbox, a repo, a price. Halo runs it on your Mac and pings you only when something needs you, never sending or buying on its own.
How it works
Everything happens on your Mac. There is no server in this loop.
Halo watches your screen and listens only when you ask it to. Every frame is read once, then deleted.
What it saw becomes a short written memory: the meaning, never the picture.
A finished sentence, a note, a nudge. Surfaced only when it's worth your attention.
Coming soon
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.

Not to use Halo. Everything runs on your Mac with no sign-in. A Halo Cloud subscription needs an account; a Lifetime License is tied to an email so you can re-redeem on a new Mac, but doesn't require day-to-day sign-in.
Yes. Halo is fully offline by design. Halo Cloud needs network. Bring-your-own-server mode follows whatever server you point it at; if that's running on the same Mac, it works offline too.
No telemetry by default: Halo doesn't even know how often you launch it. Crash reports are strictly opt-in from Settings → Privacy, off out of the box, and contain no screen contents or audio.
Halo sends your message over an encrypted connection. We process it under agreements that prohibit training on your data, logging your prompts, or sharing them with anyone. Your data is never sold and never used for advertising. Everything ambient (your screen, calls, memory) stays on your Mac no matter which plan you're on.
Apple Silicon (M-series) and macOS 26 or later. Halo will not run on Intel Macs.

Halo is free forever. If it's useful, you can support development.
