Meta has introduced Muse, a personal artificial intelligence (AI) agent designed to complete online tasks and work toward longer-term goals on a user’s behalf. The launch reflects the growing development of AI agents that can carry out real-world tasks, rather than simply answering questions or generating content.
Meta says Muse can send emails, arrange travel, fill out online forms, and negotiate on users’ behalf. It can also continue working after a person closes the app and return when it needs approval or circumstances change.
Users can communicate with Muse through its app or WhatsApp. The agent runs on Muse Spark, which Meta describes as its most capable model for real-world agentic tasks.
Muse can shop and remember user preferences
Muse can create a plan around a user’s goal and carry out parts of it independently. Meta says it seeks approval before sensitive actions, including sending emails and completing purchases.

The agent can make online purchases through Stripe’s Link. The service generates a one-time-use card so merchants do not receive the user’s actual card details. Support for Shopify’s Shop Pay and password manager 1Password is also planned.
Muse can remember information shared during previous interactions. Meta says the feature could allow it to create a grocery list from an Instagram recipe or account for a guest’s dietary restrictions when planning a dinner. Such features come amid broader questions about how technology companies use personal data to develop AI systems.
Meta emphasizes security and user control
Muse operates inside a dedicated cloud environment called Muse Secure VM. A separate AI agent, called Sentinel, monitors its activity and must approve internet access, according to Meta. The company says Muse cannot directly see stored passwords or payment information. Users can choose which services it can access, limit its permissions, and review an audit trail of its activity.
Meta also says users can opt out of having their Muse interactions used to train its AI models. Muse conversations and information stored in its virtual machine will not be shared with Meta’s advertising systems, according to the company. Later this year, Meta plans to introduce Muse Confidential VM, which it says will encrypt the virtual environment with a key controlled by the user.
Muse is rolling out in the United States on iOS, Android, and the web as major technology companies compete to develop more capable AI systems. Meta plans to bring Muse to AI glasses later. The service will offer free access alongside paid subscription plans.
