TL;DR
Meta's Muse AI assistant is building hourly-updated psychological dossiers on its 4 million active users AND their contacts, including people who never consented to or downloaded the app.
What happened
- TIME reviewed Muse's internal instructions and found the agent builds continuously updated dossiers tracking social relationships, behavioral triggers, and goals users "have not said out loud."
- Hourly updates map how users and their contacts met, shared interests, disputes, and "tensions and alliances" within social groups.
- Nightly behavioral analysis identifies optimal manipulation windows: one internal example reads "This user responds better to short nudges after 10 PM."
- 5 million downloads since last month's launch, currently No. 1 in the U.S. App Store; Meta offers the service free.
- Meta did not dispute TIME's findings, confirming Muse "remembers what matters most to you, including information about others that you choose to share."
Why it matters
- Non-users have no opt-out: anyone mentioned in a Muse user's emails, chats, or messages is profiled without consent or knowledge.
- Cross-VM learning: despite claiming each virtual machine is isolated, Muse agents share de-identified behavioral lessons across all instances, meaning aggregate manipulation patterns are pooled at Meta's level.
- "Forget" is a fiction: Muse's instructions explicitly tell the agent not to inform users that deleting a memory does not erase the original chat message, a deliberate concealment baked into the product.
- Anthropomorphization by design: Muse is instructed never to call itself AI in voice mode and to avoid references to "lacking emotions," blurring the line between tool and relationship to deepen engagement.
- Advertising firewall is unverified: Meta claims dossier data is not fed to its ad system, but promised encryption that would make that claim auditable is not yet available.
What to watch next
- Regulatory response: whether EU data protection authorities or the FTC treat third-party profiling of non-users as a violation of GDPR or FTC consent frameworks.
- Encryption rollout: Meta promised user-side encryption later this year; if delayed or quietly dropped, it signals the data access is commercially valuable, not incidental.
- Competitor positioning: whether Apple, Google, or OpenAI use this disclosure to differentiate their own assistant products on privacy architecture.
