Haven't downloaded Meta's new AI agent?
Even if it's a hard pass for you, Muse still keeps a file on you, according to its own operating instructions.
Muse launched September 8 and reached an estimated 10.9 million downloads worldwide by October 20, according to Sensor Tower. People connect it to their email, calendar, and messages, even to their bank accounts and health data. WIRED reported that independent AI researcher Karan Joshi got Muse to reveal that it was instructed to keep "a page for every person in the user's life." Family. Friends. Partners. Coworkers.
Those people don't use Muse, and as researchers wrote, they "have no say in being profiled." Their information still ends up working for Meta. Meta has to know the people around you to be useful, and Muse works from public information and what users choose to share. But it wouldn't be the first time Meta kept tabs on people who never signed up. In 2018, Mark Zuckerberg told Congress that Facebook collects data on non-users.
What you tell Meta's AI
Since December 2025, what people say to Meta AI has shaped the ads they see across Meta's apps, and in most countries there's no way to opt out. That's a billion monthly users whose questions, worries, and plans can become ad signals. Help with a budget, a gift for a partner, a job they want to quit: every question reveals what someone needs, fears, or wants to buy. You produce it. Meta sells access to it.
Meta says Muse isn't connected to its ad system. But Muse is designed to know your inbox, your calendar, your bank account, and the people in your life, and the line between Muse and Meta's ads is a company policy. Policies can change.
Follow the money
In the third quarter of 2026, Meta earned $63 billion from advertising. That's nearly 98 cents of every dollar it brought in, and an average of $17.72 per person in just three months.
What did those people get in return? Free access. You supply the raw material, and Meta sells it to advertisers. That's data exploitation: the value is created by you and captured by someone else.
It's also why Meta put 39 percent of its October ad spending into promoting Muse, according to Sensor Tower. An agent inside your inbox, calendar, and bank account is the richest data source Meta has ever built. And even Muse's "forget" command, TIME found, doesn't necessarily erase the message that contained the secret.
What families are up against
Muse is adults-only, but the people in a user's life get a page, too, kids included. The nonprofit Fairplay says Muse's cuddly mascot, Jolly, is built to appeal to young children. Its striking resemblance to Disney Pixar's Baymax is deceptive. And in December, Meta plans to ship Muse Charm, a Tamagotchi-style gadget with a camera and microphones.
According to Pew Research Center, 64 percent of U.S. teens use AI chatbots, but only about half of parents say their own teen does. When a kid confides in a chatbot, that conversation may become data. Our kids are growing up generating value they'll never see, for companies they never chose.
Own Your Data®
Giving up on AI isn't the answer. The problem isn't that an assistant knows you. It's who owns that knowledge, and who profits from it.
With data ownership, an AI assistant can still remember your plumber, plan your week, and help with your budget, without a company keeping a copy of your life to sell. You decide what gets shared, with whom, and for how long. And when your data creates value, you share in it.
That matters more as the Agentic Web arrives, where AI agents will shop, book, compare, and negotiate on our behalf. Whoever owns that data will own the value it creates. If that's Meta, the Agentic Web becomes the most complete surveillance system ever built. If it's you, you get the full benefit of AI and keep control of the information that makes it work.
The question isn't whether to use AI.
It's whether your AI works for you or for an advertiser.
Your data has value. It should be yours.
