Meta introduced Muse on Tuesday, the personal AI agent it has been signalling for a while. Underneath sits a model of its own, Muse Spark.
What Muse is supposed to do
The agent connects to the services you already use: mail, calendar, payment providers, health apps, smart home. From there it does things rather than just answering — sending emails, booking travel, filling in forms, getting bills lowered, turning a recipe into a grocery list, actually making purchases.
You get it on the web at muse.ai, as an iOS and Android app, and inside WhatsApp. Meta’s AI glasses are supposed to follow.
Pricing: a free tier to start, “Power” at $20 a month, “Maximum” at $100. The app carries usage meters that warn you before you cross into a paid tier.
The elephant in the room
An agent that can see your inbox, your calendar, your health data and your payment methods at the same time is the most trust-intensive thing you can hand a company. And the company asking is Meta.
Meta’s answer is technical: a “Muse Secure VM” isolates the data and is meant to keep passwords and payment details out of the agent’s view. Reasonable on paper. Nobody outside Meta can verify it yet.
TechCrunch, in its write-up, walks through the FTC settlements of 2011, 2019 and 2023, the passwords stored in plaintext, and Cambridge Analytica. The closing question lands: will personal connection and usefulness be enough for people to trust Meta with their data one more time?
My read
Functionally this is a direct move onto ground where Anthropic sits with Cowork and OpenAI with its agents. The difference is reach. Meta has WhatsApp, a channel billions of people are already in every day. No download, no new habit to build.
Which is why the pricing tiers interest me more than the feature list. A hundred dollars a month is not a consumer price. Meta evidently believes there are people who will pay that for an agent with full access. I’m curious whether that holds — and who reports the first data mishap.
