Meta's Muse keeps hourly profiles of people in your life

Meta's new personal AI agent, Muse, builds and updates 'relationship pages' on an hourly basis for the people in a user's life, including people who have never used the product themselves, Gizmodo reported after independent researcher Karan Joshi extracted the agent's system instructions and shared them with Wired.

The pages, according to the extracted instructions, include a person's name and connection to the user, recurring topics such as apartment moves or savings goals, birthdays and anniversaries, a running history of events and milestones, an assessment of closeness and relationship foundation, and current 'relationship needs.' The Future Society separately published system instructions from an exported Muse virtual machine, corroborating what Joshi found.

"They're trying to know you like a friend, which is honestly pretty creepy," Joshi told Wired.

Meta frames it as table stakes for a useful agent. A company spokesperson said Muse gathers context 'based on public information and from what you've chosen to share, which is how it remembers the person who just sent you an invoice is in fact the plumber who you previously hired to complete some work in your bathroom or which flowers your spouse said they liked best,' and said data is stored in each user's 'dedicated secure virtual machine.'

Muse launched on September 8, 2026 and climbed to the top of Apple's U.S. App Store free iPhone chart. Pushback has come fast from the places the agent needs to transact. Amazon blocked Muse from shopping on its platform in September, saying Meta had not notified it in advance that the agent would access its online shop and raising concerns about credential and account data handling. Meta also patched a zero-day flaw in the Mac client that could have let malware already on a user's computer hijack the agent and misuse the permissions a user had already granted it.
