Meta Chief AI Officer Alexandr Wang announced Muse, an always-on personal AI assistant that can drive a browser, connect to your apps, and is built around security. Each Muse runs in its own secure VM; a separate Sentinel system checks every action before anything leaves the VM, and the agent never sees real passwords or card numbers. Rolling out in the US today via the App Store and web, with more countries coming soon.
