Meta's new personal AI assistant, Muse, succeeds where competitors have failed by combining solid underlying models with thoughtful product design—a persistent avatar interface, smart suggestions, and deep integrations with your existing apps and data. The real advantage lies in Meta's ability to build and monetize an AI-powered feed using the same algorithmic expertise that powers their social platforms.

• Muse solves the "blank page" problem that kills most AI assistants through an Ideas tab that suggests tasks based on your connected services and chat history, plus a separate Feed showing timely information from your calendar, email, and interests.
• The product prioritizes security by sandboxing user data on individual cloud instances and keeping passwords away from Meta's systems, which the author credits as essential to making people comfortable connecting sensitive personal information.
• Meta's existing dominance in feed algorithms and massive ad infrastructure positions them to turn Muse's information feed into a highly targeted advertising platform—their real path to profitability.
