Muse Home: a greeting, a task ready to send to Scout, and a Getting started checklist over the Highfell valley
Home · Work spaceWhere every day starts

Your life isn’t one thing. There’s work, there’s family, and there’s the project you build at night. Muse gives each of them its own space on your Mac, with its own memory and its own AI helpers.

— everything in its place, and looked after.

Spaces

One Mac.
Every part of you.

A space is a whole separate place: its own memory, agents, chats, files, automations and even its own look. Switch with one click from the top of Home. Nothing leaks from one to another unless you let it.

Space one

Work

  • Remembers your clients, your tone, last week’s decisions
  • Agents Scout researching, Iris on the inbox
  • Morning meetings, replies you owe, what shipped
Space two

Personal

  • Remembers the kids’ timetable, the trip, the boiler man
  • Agents one planning the holiday, one on the admin
  • Morning the school run, renewals, birthdays coming up
Space three

Side project

  • Remembers the idea, the plan, what you tried
  • Agents Forge building at night, Quill on the launch post
  • Morning what got done while you slept

your work agents never see your family’s calendar. promise.

A day with Muse

It runs while
you live.

An operating system works in the background so you don’t have to think about it. So does Muse.

  1. Your brief is written. Each space’s agents read your calendar, inbox and tasks, and leave you a short page for the day.
  2. You open Home. “Good morning, Max.” Three meetings, two replies you owe, and the pricing table Scout finished overnight.
  3. You ask once. “Prep me for the Acme call.” Scout pulls the history, the open questions and what you need to decide.
  4. An automation runs. Every weekday at two, Hunter checks for new signals and updates your dashboard.
  5. Something needs you. Iris has drafted a reply to Jo. Muse asks once, in one place, and waits.
  6. You switch to Personal. Different memory, different agents, different morning tomorrow. Work stays where it belongs.
Why “operating system”

The computer,
rethought.

Your Mac organises files and apps. Muse organises the work itself, and the people (agents) doing it.

Desktop
Home. Your day, your cards, and one box to ask anything.
User accounts
Spaces. Work, Personal, whatever you need, kept apart.
Apps
Agents. Hire a bot for a job, start a session for a task, put a team in a room.
Your files
Memory. What you’ve told it and what it has learnt, shared with every agent in the space.
Background tasks
Automations. Plain-words schedules that run without you.
Notifications
Needs you. Only decisions. Never noise.
Documents
Docs, sheets, slides and dashboards your agents write and keep current.

Local by default.

Your work, files and history stay on this Mac unless you choose a cloud service.

Your AI, your accounts.

Runs on the Claude and Codex subscriptions you already have, and switches when one hits its limit.

Never paste a key.

Apps connect by signing in through your browser. Nothing secret goes into a chat.

Open source.

Every line is on GitHub. Read it, build it yourself, or help make it better.

Works with

The agents you already trust.
