On September 8, 2026, Meta announced "Muse," a personal AI agent that can handle tasks such as sending emails, booking travel, and shopping on behalf of the user. Rather than simply answering questions, Muse is an AI capable of operating a dedicated browser to perform actual tasks, with a system that allows it to continue working even after the application is closed. The AI model powering Muse is "Muse Spark 1.3," released in September 2026, which is specialized for long-term tasks and agent-based processing.

Muse can be used via a chat interface. For example, if a user consults it about a trip, Muse can handle everything from creating an itinerary and researching flights to booking restaurants. It also performs product comparisons and handles purchase procedures. For payments, it utilizes Stripe's "Link," employing a system that uses disposable card numbers so that actual card details are not passed to merchant sites.
Regarding security, Muse operates within "Muse Secure VM," a dedicated virtual machine providing an isolated computing environment for each user, separating them from other users' environments. Furthermore, an AI agent called "Sentinel," which manages permissions, monitors access and operations on external services and requests user permission as necessary.
Muse has begun rolling out in the United States for iOS, Android, and the web (muse.ai). Integration with WhatsApp and support for AI glasses are also planned. The release date for Japan is currently undecided.
