Picture an AI agent that already knows your daughter’s soccer schedule, your usual table at the Italian place, the raise you plan to ask for and the trip you’re saving for. It never asks, because it was there for every conversation that told it.
Hundreds of articles have covered what data these agents collect and how to stop them, but limiting what they know about you only makes agents worse, because what they collect is what makes them great.
Nothing, then six at once
All through 2026 the big AI labs promised a personal agent that would run your life for you. Then, in a span of a few weeks, Meta launched Muse, OpenAI launched Dots, Google launched Gemini Spark, Anthropic launched Claude Duet, xAI launched Grok Bot and a startup launched Instinct. By late October WIRED had reviewed all six side by side for its general audience, a sure sign they’re mainstream products now, not toys for developers.
Every one of them starts learning who you are the moment you sign up. Muse is the one we know the most about. Muse describes its own memory as a system that runs whether you open the app or not, and the internal instructions reported by TIME in October back it up.
How Muse remembers you
At the centre of the Muse memory system is a file about you called MEMORY.md, holding the facts, preferences and decisions Muse thinks are worth keeping, and Muse reads that file at the start of every conversation. Beside MEMORY.md sit dated daily notes and a file for each person in your life, kept current from your chats, messages and email.
The upkeep runs on a clock. Every hour Muse folds your latest conversations into your main file and refreshes the people files. Every night Muse reviews your conversations for patterns, works out goals you “have not said out loud,” and reorganizes your main file before morning. Muse also logs what Meta calls trajectories, each request you make or task it performed and how it turned out.
Mention on a Monday that you like short answers late at night. Within the hour it’s in your main file, and if your partner came up, it’s in the file about them too. By the next week the nightly review has turned that into a rule about how to talk to you. Muse is building a Personal Context Library, a record of what you’ve said, shared and done with an AI, organized and kept current around the clock, and all six agents are building the same thing.
What Meta can do with it
Under Muse’s terms, Meta can store, copy, change, display and share everything you give Muse, including what Muse pulls from your email and calendar and anything Muse builds from that, anywhere in the world. Meta can hand those rights to other companies, as long as it’s to run and improve Muse.
Meta also logs everything Muse does for you and keeps those logs, including for legal reasons, so they can be handed to a court. Link Muse to your Facebook or Instagram account and Meta can combine what it knows about you across all of them. Meta also warns that deleting something won’t necessarily make Muse forget it.
Agents don’t work if they don’t know you
Your doctor knows your health, your accountant knows your money and your closest friend knows what’s going on at home. A personal agent that runs your life needs to know all of it, and the agent keeps getting better with every conversation you have with it, so there’s no way around the data collection.
That’s where it gets uncomfortable. Meta, Google, OpenAI and xAI all make money from advertising, and an ad business earns more the better it knows you. Those businesses have an incentive to use the data they have about you to match ads to your purchase intent.
The more of your life one agent holds, the more you’re worth to the company behind it, so none of them will make it easy to take that history to a rival. A context library you own and control changes that. You choose which agent reads your context library and how much that agent sees, you take your context library with you when you switch, and nobody makes money from your life without asking you first.
