Meta introduced Muse on September 8, a personal AI agent that the company says goes beyond answering questions to actually complete tasks: booking travel, lowering a bill, or turning a saved Instagram recipe into a grocery list.
Muse runs on a dedicated Muse Secure VM, a virtual machine that holds both the agent and a person's data, and it talks to people the way they already message friends, through the Muse app or directly inside WhatsApp. The system is powered by Muse Spark, which Meta describes as its most capable model yet for agentic work: opening a browser, filling out forms, and continuing a task after the app is closed, then returning when it needs a decision, such as approving an email or a purchase. Meta says Muse is rolling out first in the US on iOS, Android, and muse.ai, with support for its AI glasses to follow, and that it will be free for most everyday use with paid tiers reserved for heavier workloads.
The safety pitch is central to how Meta frames Muse. A separate Sentinel agent runs alongside Muse on the same isolated machine, kept apart from it at the system level, and nothing Muse does reaches the open internet unless Sentinel approves it. Muse checks with the person before sensitive steps like sending an email or making a purchase, and it has no visibility into raw passwords or card numbers; those live in a separate secure store the agent can use without reading them. Purchases route through a one-time virtual card issued via Stripe's Link, which Meta says is the first agent checkout covered by Link's damage, price-drop, and no-fee-return protections. Meta says it will follow with a stricter Confidential VM tier that encrypts an entire session with a key only the user holds, a step past what most consumer AI assistants offer and a quiet admission of how much account access an always-on agent like Muse would otherwise demand.
Meta calls Muse the first personal AI agent built for a mass audience, pitched as needing no technical skill to use out of the box and positioned against the assistants OpenAI and Google are also chasing. How well that claim holds will depend on whether Muse can actually finish the multi-step, real-money tasks, like booking a flight or lowering a bill, that most agents today still hand back to a person partway through.
