Meta's Muse AI Agent Defaults to Training Data on User Chats While Requesting Financial and Personal Documents

Meta has launched Muse, a personal AI agent introduced September 8 that can book appointments, manage finances, and execute household tasks—but the service collects user conversations for AI model training by default and actively nudges users to share bank account, email, and passport information. The app has become the most popular free application on the iPhone App Store, with over 2.5 million downloads since its debut. Built on Meta's Muse Spark multimodal AI model, the agent operates through a specialized infrastructure that Meta calls Muse Secure VM, a dedicated isolated cloud computer that processes user requests.
