Meta’s newly launched Muse personal artificial intelligence agent app has shot straight to the top of the Apple App Store. The viral app debuted earlier this month and quickly surpassed OpenAI’s ChatGPT as the top free app.
The rapid rise of Muse highlights a major shift in how consumers use artificial intelligence. Instead of traditional chatbots that merely answer prompts, agentic apps actively perform real-world tasks.
The Muse AI agent launched in early September with deep integration across multiple categories. It connects to personal apps for email, calendar, payments, health, shopping, and smart homes.

Modeled on the open-source OpenClaw project, Muse can autonomously handle complex operations. The agent can send emails, book travel itineraries, sell vehicles, and negotiate lower bills.
Users retain full control over their data and permissions within the app. People can choose which third-party applications the agent connects to and revoke access at any moment.
Every Muse agent operates inside its own secure virtual machine. This cloud-based personal computer emulation allows the software to execute tasks in the background when the app is closed.
Powered by Meta's custom Muse Spark model, the system develops personalized plans to achieve user goals. It opens web browsers, fills out online forms, and coordinates schedules independently.
The assistant pauses its work to request user approval before executing sensitive steps. It always asks for a green light before sending emails or purchasing items.
Muse also retains long-term memory regarding personal preferences and past events. It can make unprompted suggestions based on details mentioned only once in passing.
As an example, Meta demonstrated how Muse can turn a saved Instagram recipe reel into a grocery list. The agent can then build a dinner party menu while checking dietary restrictions from prior gatherings before dispatching digital invitations.
5 things to try with @Muse this weekend beyond the usual email, calendar, and subscription workflows:
1. Set up a personalized feed
Muse's Feed is refreshing because it doesn't have AI slop or ads.
You can personalize it around the exact topics you care about, plus reminders… https://t.co/Xxbjv3A1mP pic.twitter.com/vOFyOvFK5J

Granting an AI agent access to personal applications naturally introduces significant safety and reliability challenges. Meta previously delayed the release in April to overhaul security protections.
"The additional work allowed us to cross the threshold and meet minimum requirements for product safety, security, privacy, model performance and other metrics," said Vishal Shah, vice president of AI products at Meta.
To further protect user privacy, Meta plans to roll out Muse Confidential VM later this year. This upcoming feature will encrypt all user communications and personal data so that only the user holds the key.
