Meta Muse

// Overview

Meta Muse is a personal AI agent that carries out tasks on your behalf rather than only answering questions. You talk to it the way you message a person — in the standalone Muse app, on the web at muse.ai, or directly inside WhatsApp — and describe what needs doing. Muse turns the goal into a plan, opens a browser, fills out forms, and keeps working after you close the app, coming back when something changes or when it needs your approval. Meta's own examples range from sending an email or booking travel up to selling a car, lowering a bill, or maintaining a year-long training plan.

The distinguishing piece is the isolation model. Each person's agent runs on Muse Secure VM, a dedicated cloud virtual machine that holds both the agent and the credentials for every service the person connects. A second agent called Sentinel runs on that same machine but is separated from Muse at the system level, and nothing Muse does reaches the internet unless Sentinel approves it. Credentials go into secure storage so the agent can use a password or a card without seeing it, and Muse checks with the person before sensitive actions such as sending mail or making a purchase. Meta says it will add a Muse Confidential VM later, encrypting the whole VM with a key only the user holds.

Muse is powered by Muse Spark, Meta's most capable model, and shares its name with that model family. It remembers details you mention once and can act on them unprompted — turning a saved recipe reel into a grocery list, or recalling a friend's dietary restriction before sending invites — and you can tell it to forget specific things. Payments run through Link built by Stripe, whose agent wallet issues a one-time-use card; Meta says Muse is the first AI agent covered by Link's purchase protections, with Shop Pay and 1Password support announced as coming.

// What it does

• Chat-first interface in the Muse app (iOS, Android and macOS), on muse.ai, and inside WhatsApp
• Mac app that acts inside native applications — files, Messages, Calendar, Notes and Mail — with access granted per app
• Long-running agentic work: builds a plan, browses, fills forms and continues after you close the app
• Per-person Muse Secure VM that isolates the agent and its stored credentials from every other user
• Separate Sentinel agent that must approve anything leaving the machine, plus a permission prompt before sensitive actions
• Full audit trail of what the agent has done and what it plans to do, with per-service access controls you can revoke
• Checkout through Link built by Stripe using one-time-use cards, with Link purchase protections
• Persistent memory you can selectively make it forget, and an opt-out from training Meta's models

// Getting started

Muse is a consumer product, not a package you install. It is US-only at launch and limited to people 18 and over.

// When to use it

• Handing off a multi-step errand — comparing options, booking, and filling in the forms — instead of doing it tab by tab
• Online shopping where the agent pays with a one-time-use card rather than your real card details
• Turning a long-term goal, such as a training plan or setting up a business, into a plan the agent keeps advancing
• Delegating routine correspondence and scheduling, with an approval prompt before anything is actually sent
