Alongside three fresh pairs of glasses, Meta slipped out a fourth device with no lenses at all. The Muse Charm is a small keychain gadget that carries the company’s autonomous AI agent in your pocket.

Details are thin. Meta has confirmed the Charm holds a real-time voice model so wearers can talk to Muse without putting glasses on, and that it clips to a keyring. No price or full spec sheet has been published, and the company says only that it should arrive around December.

Launch coverage suggests the device includes a camera, which would let it answer questions about its surroundings instead of simply relaying voice. Meta has not spelled out what that camera can and cannot do, or how recording is signalled.

The Charm fits a pattern Meta has been building all year. Its Ray-Ban Display glasses already run Muse, the app is picking up Spotify controls, and the agent is being pitched as the layer that follows a wearer from phone to glasses to, now, a pendant.

It also lands in a crowded field. Dedicated AI pins and pendants have struggled to justify their price, and Meta’s own launch was quickly folded into coverage joking about AI Tamagotchis.
