Meta's AI agent Muse has become a viral hit, with millions of users downloading the assistant and connecting it to bank accounts, messages and health data. But according to internal system prompts extracted by independent researchers and shared with WIRED, the app also builds detailed profiles of the people in your life.
One instruction reportedly tells Muse to create "a page for every person in the user's life," compiling information on family, partners, friends, colleagues and people you follow. The hourly process uses the agent's structured memory files to store facts, history and relationship details — and even suggests ways to strengthen those relationships. Meta says the files were meant to be accessible for transparency.
What the leaked Muse prompts reveal
Independent AI safety researcher Karan Joshi extracted the instructions by asking Muse through its regular chat interface to copy and share its own software files, then passed the findings to WIRED. The documentation shows that a person's profile can start empty and fill up over time with sections such as Facts, History, The relationship, In common, Open threads and Strengthening.
According to the prompts, Muse should record where people live, what they do, recurring threads like an apartment move or a shared savings goal, and important dates such as birthdays or anniversaries. A person's history might include a past trip, a resolved argument or a recent milestone. The Strengthening section suggests actions like a reason to call, a date worth remembering or something they said to circle back on.
Meta says Muse only uses available evidence and considers invented details worse than an empty page. The company also stresses that each user has a dedicated virtual machine storing their data, that memories can be wiped or external services disconnected at any time, and that the agent seeks human confirmation before actions like sending an email or making a purchase. A spokesperson told WIRED that context about users and their contacts is necessary for any agent to be useful.
