Meta’s new AI agent app Muse hit No. 2 in the US App Store within two days of its September 8 launch.
The company characterized Muse’s opening as “a slower start” compared to previous launches like Threads or Meta AI.
What Muse actually does
Muse is not another chatbot. It’s a personal AI agent designed to handle multi-step tasks: booking travel, managing calendars, making purchases through Stripe Link, and executing workflows that go beyond the standard “ask a question, get an answer” loop.
The app runs on Meta’s Muse Spark model family, specifically version 1.3, which rolled out in early September 2026. Each user’s Muse operates on a dedicated secure virtual machine in Meta’s cloud.
