What is Meta Muse? Meta's AI agent explained

Muse refers to two related things. First, the Muse family of AI models built by Meta Superintelligence Labs (MSL), starting with Muse Spark. Second, Muse, the personal AI agent, an app powered by those models and designed to do work for you rather than just answer questions.

According to Meta, Muse is built to do work for you. It can take on tasks like sending an email or booking travel, build a plan for a larger goal, open a browser, fill in forms and negotiate on your behalf. It keeps working after you close the app and comes back when something changes or it needs your approval, and it remembers what matters to you. You can message it in the Muse app or in WhatsApp.

It is an example of the agentic AI pattern: a goal, a plan, tools, and checkpoints with a human.

• An isolated virtual machine holds your agent, your data and the credentials for the services you connect, so no one else's agent can reach it.
• A Sentinel agent on the same machine must approve anything Muse sends to the internet, and asks you when needed.
• Approvals — Muse checks with you before sensitive actions such as sending an email or making a purchase, and shows an audit trail of what it has done and plans to do.
• Passwords and payment details — Meta says Muse has no visibility into them; shared credentials go into secure storage it can use without seeing.
• Ads — Meta says Muse doesn't share your conversations or VM data with its ad systems.
• Control — you choose which apps it connects to, can disconnect them, tell it to forget things, and opt out of having your interactions used to train Meta's models.

Meta says Muse checks out with Link by Stripe using a one-time-use card, and that it is the first AI agent covered by Link's purchase protections. So Muse buys with a card rail, not crypto. The same shift — software that can complete a purchase — is why stablecoin payments to an address are also of interest for agents, as covered in what is agentic AI.

• Where: rolling out in the US on iOS, Android and the muse.ai website, with AI glasses described as coming soon.
• Cost: Meta says Muse is free for most of what people need, with subscription plans for people who want to do more. Reported plan prices vary between outlets, so check Meta.
• For developers: Muse Spark 1.1 is available through the Meta Model API (public preview), and Muse Glimmer's open weights are on Hugging Face under Apache 2.0.

An agent with access to your email and purchases is powerful and carries real risk: mistakes in long tasks, malicious instructions hidden in web pages, and the trust you place in the provider's safeguards. Meta's design — isolation, approvals, an audit trail — addresses these, but independent reviews will take time. Start with low-stakes tasks and keep approvals switched on.
