Meta introduces Muse, a personal AI agent designed to handle tasks across web browsing, app integration, and automation. It operates on a secure virtual machine, keeping user data private with features like credential storage and purchase protection. Users interact via chat, approve critical actions, and can delegate tasks that run in the background.

Muse builds custom tools when needed and integrates with apps like email and Instagram. It emphasizes user control, transparency, and safety, with free access and optional upgrades.
