Muse

What it does

Muse is Meta's personal AI agent, launched September 8, 2026 in the US and Canada (18+). Unlike a chatbot you open and close, Muse is always on: each user gets an isolated cloud computer (the Muse Secure VM) with its own browser, so it keeps working on tasks in the background even when you walk away. It's powered by Meta's Muse Spark model family and works across the Meta ecosystem.

Who it suits

Best for people who want an AI that does things for them in the background, not just answers questions in a chat window.

Why it's trending

Hit #1 on the US App Store within days of its September 2026 launch, with roughly 3.4M downloads in the first two weeks per Sensor Tower — one of the fastest AI app launches ever.
