Just say it.
Halo does it.

Halo is an AI that uses your computer for you. Press one key and say what's wrong, the way you'd tell a grandkid. Halo sees your screen, fixes it, and asks before every change.

Halo is listening
Animated walkthroughs of real Halo tasksSound plays when you pick one
01 · How it works

No menus. No settings. No jargon.

Halo starts from the way people actually ask for help, not from a perfectly worded command.

  1. Press one key

    Ctrl Alt D from anywhere. Halo appears where you are and listens.

  2. Say what's wrong

    "The sound thing is broken." "Make the words bigger." It reads your screen to work out what you mean.

  3. It takes care of it

    It tells you what it will change, does it, and checks that it worked. Or it points at the button, if you'd rather learn.

02 · Who it's for

AI agents are built for experts. Halo is built for everyone else.

Today's agents make people who already know computers faster. Halo is for the people who'd otherwise call a family member, or a stranger who says they're from tech support.

$1 billion+ lost by Americans over 60 to fake tech-support scams in 2025, according to FBI data.

Typical AI agent
Halo
You type a clear, well-worded request
You talk, the way you'd talk to a person
You already know what the problem is
It works out the problem from your screen
You're expected to catch its mistakes
It assumes you can't, and is careful for you
Lives in a chat window or a browser
Works on your real computer, across your apps
"Can you come over and fix the computer?" Halo is for every family that has heard that sentence.
03 · Safety

It asks first. Every time.

Letting software use your computer takes trust. So Halo has hard limits it can't cross, no matter what a website, an email or anyone else tells it.

Asks before it changes anything
Every change is read back to you first, in plain words.
Never touches passwords or payments
Passwords, payments, sign-ins and permissions stay with you.
Never deletes anything for good
Nothing Halo does is permanent.
Watches for common scams
Spots well-known patterns, like fake "virus" warnings, and tells you before you act.
Private beta · Mac and Windows

Help, the moment
you ask for it.
