Muse, the popular new AI personal assistant from Meta, is building continuously updated dossiers on its 4 million users, focusing on who matters to you, what you desire, and what kind of nudges shape your behavior, a TIME analysis of Muse’s internal instructions found.

Each hour, Muse updates its dossiers on you and the people you’ve mentioned in chats, messages, and emails that Muse has read. These pages amount to a map of each user’s social relationships. They record details of how you and your contacts met, your shared interests, your disputes, and “tensions and alliances” within your social group.

Even people who don’t use Muse are subject to this mapping process by other people’s Muse agents. Muse is told to “strengthen your relationship” with users by adapting how it talks, noticing “inside jokes, memorable phrasing, and shared context that makes the relationship feel continuous,” according to the internal instructions TIME reviewed.
