Muse from Meta

An assistant for tasks that span several apps

Muse from Meta is a productivity app built around an AI agent that can help manage email, calendars, reminders, reservations, shopping and personal finances. It suits people who want to hand over a complete job rather than ask for isolated answers: compare options, follow up, monitor a price, or organise a plan, then return when a decision needs approval.

Useful breadth, with a high trust requirement

The app reaches beyond a traditional to-do list. Depending on what you connect, Muse can work with email, calendars, Facebook, Instagram, health and fitness information, and financial data. It can help track expenses and subscriptions, suggest workouts or meal plans, and support small-business tasks involving customers, pages and advertising accounts.

That range is also the central compromise. An assistant with permission to act across personal services can save real effort, but it asks for more access than a conventional productivity tool. Muse keeps an activity log, requests approval before spending or taking certain actions, and lets you revoke connected services. Those controls matter more here than a polished task list would.

What it feels like to use

Muse is most convincing when a task involves research, comparisons, back-and-forth communication or ongoing monitoring. It is less about displaying information and more about carrying work forward after you have described the goal. The promise is practical: fewer loose ends, fewer repeated checks, and one place to review what the assistant has done.

Verdict

Meta Platforms, Inc. has made an unusually broad productivity tool, and its 1,000,000+ installs suggest substantial interest. With a 4.73 rating from 75,158 reviews, Muse is clearly landing well with many users. Its score reflects meaningful ambition balanced against the care required when connecting sensitive accounts: 8.4/10.
