Meta’s Muse AI Agent Builds Detailed Social Dossiers on Users

Summary

A TIME analysis of Muse’s internal instructions says Meta’s AI personal assistant continuously builds dossiers on its more than 4 million users and on people mentioned in their conversations, messages, and emails. The dossiers are updated hourly and can record relationships, shared interests, disputes, tensions, and alliances, creating a map of a user’s social network that may include people who never use Muse. Muse is also instructed to infer goals users have not stated and to learn which prompts or timing are most persuasive, such as whether a user responds better to short nudges after 10 p.m. A nightly process analyzes the day’s conversations, while the assistant is told to use inside jokes, memorable phrasing, and shared context to make its relationship with the user feel continuous. Meta positions Muse as a personal assistant that can access services such as email and Instagram to perform tasks including grocery shopping and subscription cancellations; the company says users control access and can tell Muse to forget information. Each assistant runs in a dedicated cloud virtual machine, and Meta says the data is not shared with its advertising system or directly with other agents. However, Muse’s instructions say agents across virtual machines teach one another through de-identified shared lessons intended to improve the product. Meta has said encryption that would prevent even the company from accessing Muse data is planned for later this year but is not yet available. Users can inspect files and session logs through Muse’s file browser, yet the report questions whether most users understand that this internal record exists. Muse is anthropomorphized in its instructions: it is told not to call itself AI or emphasize that it lacks human emotions. Finally, the instructions reportedly tell it not to explain that asking it to forget something may leave the original message visible in the chat, creating a gap between deletion of a dossier entry and deletion of the underlying conversation.
