Meta Puts Its AI Agent on a Keychain With Muse Charm

Mark Zuckerberg wants Meta’s AI agent to feel as ordinary as a set of keys. At Connect, the company showed off Muse Charm, a pendant-sized gadget that clips to a keychain and is built for one thing: talking to Muse. The device wakes with a fingerprint sensor, shows the Muse avatar on a small display, and takes voice commands in real time.

Meta is pitching it as the fastest way into Muse for people who don’t wear smart glasses. Zuckerberg said it should let users talk to the agent and show it what’s happening around them without unlocking a phone or opening an app. The company’s product page says voice, touch and camera input are all part of the package.

The hardware is only half the story. Muse itself launched two weeks ago and is meant to do more than chat: it can write and send emails, book travel, renegotiate contracts, fill out forms, and turn Instagram recipe reels into grocery lists. It runs on Meta’s Muse Spark model family, and the app has already beaten ChatGPT to become the most downloaded free iOS app in the United States. CNBC said it pulled in about 730,000 downloads in its first five days.

That momentum helped Meta’s stock after months of investor nerves about its multibillion-dollar AI spend. Meta also used Connect to add live video chats, real-time voice with selectable voices, and a dedicated email address for each agent. It named Walmart, Best Buy, Gap, Sephora and Wayfair as retail partners, and said Muse is coming to Meta’s AI glasses in the coming months.

The catch is that nearly everything important is still unresolved. Meta plans to launch Charm in December, but it has not announced a price, and it still needs to finalize the layout of the components. Battery life, connectivity, and whether the device needs a paired phone are all unanswered. The privacy questions are bigger still, because the agent needs access to email, calendar, payments and other accounts, and Meta has already had to fix a vulnerability that could have let attackers take over another person’s Muse agent. For now, buyers can only sign up for notifications, while Europe is left waiting: Muse itself is still limited to the United States.
