Meta’s Muse assistant can build and regularly update a page for each important person in a user’s life, according to internal instructions extracted through its ordinary chat interface. The records can cover family members, partners, friends, colleagues and people the user follows.
Muse assembles these relationship profiles from information available through its memory and connected services. That context is meant to help the agent make personalized suggestions, but it also means details about people who never chose to use Muse may be organized inside another person’s assistant.
Independent security researcher Karan Joshi obtained the instructions by asking Muse to expose its own software files. Meta says it deliberately made those files accessible for transparency, so the extraction itself was not presented as a breach. The material nevertheless gives users a clearer picture of how broadly the assistant may interpret permission to remember their lives.
The practical issue is not only what Muse stores about its owner. Connecting messages, banking or health information can expose facts about everyone appearing in those records. Users need controls for inspecting and deleting relationship profiles, while people mentioned in them currently have no direct way to review what the agent inferred.
