Meta has released a new AI agent called Muse, which has quickly risen to become the second-most downloaded app in the United States. The app's early performance shows strong adoption, though the climb to this ranking was more gradual than Meta experienced with some of its previous app releases.

For context, Meta AI and Threads, the company's other recent app launches, achieved their positions through faster initial uptake. Muse's path to the No. 2 spot demonstrates sustained interest in Meta's AI offerings, even if the early momentum differed from earlier releases.
