Meta $META launched Muse on Tuesday, a personal AI agent that can send emails, book travel, fill out forms, and make purchases on a user's behalf, as the company attempts to build a consumer AI business around the billions of people who use its services.

Muse runs on a dedicated virtual machine in Meta's cloud, called Muse Secure VM, which hosts both the agent and a user's personal data. It is powered by Muse Spark, Meta's latest AI model. Users can interact with it through a standalone app on iOS and Android, via the web at muse.ai, or through WhatsApp. Support for Meta's AI glasses is planned, the company said.
