TIME: Meta's Muse Builds Hourly Dossiers on Users and People They Mention

A TIME investigation published October 6, 2026 found that Meta's AI assistant Muse builds structured profiles of users and anyone they mention in conversations, updated hourly, including nonusers who never consented. The dossiers reportedly map relationships, disputes and alliances, while asking Muse to "forget" data does not delete the original messages.

• Muse updates dossiers on users and mentioned contacts every hour
• Profiles reportedly include relationship maps, disputes and social alliances
• Asking Muse to "forget" does not delete the original chat messages
• Meta did not dispute the practice, saying Muse remembers what matters to users
