Meta Launches Muse for Mac: A Personal AI Agent That Works Across Your Files, Mail, Messages, Calendar and Notes

Meta has released a personal AI agent for Mac that can access and work with files, email, messages, calendar, and notes stored on a user's computer. The agent works across native applications and can gather context from multiple sources to complete tasks like organizing folders or creating summaries, distinguishing it from chatbots that require manual information entry. Access to the computer is opt-in with user control over permissions, and sensitive actions like deleting files or sending messages require explicit approval before execution. The agent runs on Meta's cloud infrastructure using a system that isolates each user's data and prevents outbound actions without approval.
