At its annual Connect event, Meta announced Muse Charm, a palm-sized AI wearable designed as a companion to its recently launched personal AI agent, Muse. The device, revealed by CEO Mark Zuckerberg in a “one more thing” moment, has a small screen that displays Muse’s digital avatar, known internally as Jolly, giving it a quasi-Tamagotchi feel. Users can carry the totem in a pocket or attach it to a keychain, and interact with it by tapping a fingerprint sensor and speaking without unlocking a phone or opening an app. “We packed the whole Muse experience, including the whole real-time voice and avatar stack, into something that fits on a keychain and is always available to talk to,” Zuckerberg said during the keynote. He added that for people not wearing smart glasses, “this is going to be by far the fastest way to talk to your Muse and to show what’s going on around you.”

The product is not ready to ship yet. Zuckerberg said the team needed to “finalize laying out the components” and promised the devices would be “ready to ship in time for the holidays in December.” The announcement comes as AI amulets have become a somewhat clichéd form factor in consumer tech, with devices like Friend drawing skepticism. Meta’s entry is positioned as a low-stakes experiment in AI wearables that also gives the company another distribution channel for its AI agent. No pricing, battery life, or technical specifications were shared in the announcement.
