Meta’s Muse: an AI agent for your messages, browser and purchases

# What Muse does Meta launched Muse as a personal AI agent designed to take actions for users: search the open web, send emails, fill out web forms, make purchases and perform other online tasks inside apps and in a standalone Muse app. Meta presented the agent as a tool that can work across a user's digital life and announced the product publicly via social posts.

# Where Muse runs and who can use it Muse is available inside WhatsApp, a messaging app with global reach, and as a separate application. Meta's App Store listing and Muse terms state it is for users 18 and older. WhatsApp itself requires users to be at least 13 to create an account, but Muse's terms specifically deny access to those under 18.

# How this interacts with Meta's legal commitments Meta agreed to a roughly $17 billion settlement in Oakland and pledged to add age checks and teen safeguards for Facebook and Instagram. The settlement text explicitly excluded direct messaging features and products launched after the agreement—categories that include messaging apps and new AI tools like Muse. That means the settlement's safeguards do not apply to Muse or to direct messaging features that exist outside Facebook and Instagram's defined scope.

# Privacy and consumer concerns

# Usage context matters WhatsApp has large teen usage in several countries: a December 2025 Pew Research Center report found roughly a quarter of American teens use WhatsApp, and a May 2026 Ofcom report shows about 61% of U.K. teens use the app. WhatsApp also reports more than 3 billion monthly active users. Those figures matter because even if Muse is labeled 18+, its integration into a widely used messaging platform creates practical exposure points.

# Meta's product positioning Mark Zuckerberg has described Meta AI as a personal AI with emphasis on personalization, voice conversations and entertainment. In earlier public posts, he suggested people will have an AI they talk to throughout the day while browsing content on phones. Meta positions Muse as a continuation of that approach: an agent that acts for users and connects with apps they already use.

# Immediate takeaways for readers If you are considering Muse: the product can act autonomously inside apps and make purchases with permission. It is restricted to adults by Meta's terms. The product sits outside parts of Meta's recent settlement, and privacy advocates flag the risk that agentic AI centralizes user activity. If you use WhatsApp or similar platforms, check account settings, permissions and the agent's access controls before enabling any automated agent features.
