Overview
Meta Muse is the personal AI agent Meta launched for US users on September 8, 2026, led by chief AI officer Alexandr Wang and built by Meta Superintelligence Labs (MSL). It lives in a persistent chat interface: through the dedicated app, on the web at muse.ai, or directly inside WhatsApp, you give it instructions and it opens a browser inside a cloud virtual machine to carry out real tasks such as shopping, booking movie tickets, reserving restaurants, sending emails and filling forms, then comes back to you when a task finishes or needs authorization.
What sets Muse apart from ordinary chatbots is its always-on, long-running nature. Tasks keep running in the cloud after you close the app, and it returns proactively when there is progress or when your approval is needed, such as before sending an email or completing a purchase. Its built-in browser is visible to you, and cross-app memory means a recipe video you saved on Instagram can be turned into a shopping list automatically, while dietary restrictions you mentioned are factored into later dinner invitations. Under the hood it is powered by Meta's latest flagship model, Muse Spark.
Security is the headline of this release. Muse runs in a MuseSecureVM that isolates each user's workspace, every outbound action passes through the Sentinel system which either matches an authorized policy or asks you for approval, and the agent cannot override Sentinel. Purchases go through Stripe's Link single-use card numbers, so the agent never touches your real card details. Meta plans to ship a confidential, end-to-end encrypted VM before the end of the year. Commercially, Muse offers a free tier plus $20 and $100 monthly subscriptions with no advertising; Meta's longer-term ambition is to bring Muse to the billions of users across Instagram, Facebook and WhatsApp, and later to its AI glasses.
Key Features
- Always-on persistent tasks: Tasks keep running in the cloud after you close the app and only return when finished or when authorization is needed, suiting multi-step goals that span days.
- Built-in visible browser: Executes real web operations such as searching, opening pages, filling forms and completing purchases in a browser you can watch, rather than staying at the chat layer.
- Cross-app memory and connection: A recipe saved on Instagram can turn into a shopping list automatically, and preferences mentioned once are remembered for later tasks, such as avoiding a friend's dietary restrictions.
- MuseSecureVM privacy isolation: Each user's workspace runs in its own virtual machine, data is not shared with Meta's advertising systems, and queries can be excluded from being used by Meta.
- Sentinel action approval: Every read/write action against the outside world is matched against permission policies first; sensitive actions are routed to the user, and the agent cannot override Sentinel.
- Ecosystem connectors: Ticketmaster, OpenTable and Google Gmail, Calendar and Drive are integrated, and custom connectors can be built for any service that offers an API.
Use Cases
- Everyday chores: booking tickets, ordering food, shopping and filling in school permission forms, delegated with a single instruction
- Shopping and payments: purchases complete through Stripe Link single-use cards so real payment details never reach the agent
- Multi-day tasks: work continues after you close the app and reports back when progress is made or approval is required
- Instagram and WhatsApp power users: saved content turns into to-dos and mentioned preferences are remembered and applied
- Cross-service research: with Gmail, Calendar and Drive connected, the agent executes coherent tasks across Google services
Pros
- Free tier covers most everyday tasks, so the core experience can be tried at no cost
- Deep integration with WhatsApp and Instagram means the entry point is a habit users already have
- Always-on tasks with a visible browser handle real web operations, not just conversation
- The MuseSecureVM and Sentinel design make sensitive actions controllable, directly answering trust concerns about personal agents
- Payments use Stripe Link single-use cards so financial information never passes through the agent
- No advertising, with an end-to-end encrypted confidential VM promised before the end of the year
Pricing
Free tier plus $20 and $100 per month subscriptions for heavier compute use, with no advertising. Initially available in the US only, on iOS, Android and the web.
Summary
Meta Muse is the personal AI agent released by Meta Superintelligence Labs in the US in September 2026. A chat interface backed by a private cloud VM whose visible browser performs real tasks such as shopping, booking and emailing, it differentiates itself from ordinary assistants through always-on long-running jobs and cross-app memory, while the MuseSecureVM and Sentinel architecture addresses the biggest trust question around personal agents. For users willing to delegate daily digital chores to an agent, Muse is one of the most interesting new options, though users outside the US will need to wait for further rollout.
