Meta announced the Muse Charm, a palm-sized AI pendant with a 2-inch screen, fingerprint sensor, voice interface, and optional camera integration, at its September 23, 2026 Connect keynote as a dedicated hardware companion for the Muse personal AI agent. Zuckerberg targeted a December 2026 holiday ship date to capitalize on Muse's rapid early adoption—over 2.5 million downloads shortly after its September 8 launch—while accelerating an originally 2027 timeline. Only a handful of prototypes existed at announcement, with component finalization still pending, and no price or full specs have been disclosed. This positions the device amid competitive AI agent hardware efforts and past wearable failures, with trader sentiment reflecting uncertainty around production readiness before year-end.
