Meta’s Muse Charm Puts Your AI Agent on a Keychain by December

Meta saved its oddest piece of hardware for the last two minutes. At the end of tonight's Connect keynote, Mark Zuckerberg did a "one more thing" and held up a small black puck on a cord. It's called Muse Charm, Engadget's Karissa Bell put it at about the size of an Apple Watch, and its job is to give your Muse agent a body you can carry around. Zuckerberg said the design isn't finalized, but Meta plans to ship it "in time for the holidays," in December.

The Charm has a screen, and your Muse avatar lives on it. In Zuckerberg's case that's Agrippa, the toga-wearing Roman he'd been talking to all night. Tom's Guide's live notes say Meta has "only built a few of these so far," that you tap a fingerprint sensor in the corner, and that the "entire Muse AI" is built in. Engadget's Cherlynn Low said it "feels like a Tamagotchi met an AI wearable," and the stage shots back her up.

Most of the night went to Muse's new skills and to putting Muse inside Meta's glasses. During the live glasses demo, Zuckerberg asked Agrippa about an "AI charm" device. It played like a random demo question. About 35 minutes later, it turned out to be a teaser.

What Meta didn't say

Meta's Connect blog adds a little more. It says Charm pairs Muse with a "state of the art real-time voice model" in a device that fits in your pocket, and that Meta will have more to share later this year. That still leaves out most of what you'd need to decide whether you want one. Meta didn't give a price. It didn't say how long the battery lasts, whether there's a camera or a speaker, whether the Charm needs your phone nearby or has its own connection, or which countries will get it. Muse itself is available only in the US right now. Reporters in the room called it a keychain, and the stage shots show it hanging from a cord, but Meta hasn't said whether it's meant to clip on, hang from your keys, or ride loose in that pocket. Gizmodo's James Pero wrote that "details are scant."

We've seen this pitch before

Small gadgets built for talking to an AI have a rough track record. Humane's AI Pin cost $699 plus $24 a month and promised to free you from your phone. HP bought Humane's assets for $116 million in February 2025, and the Pins stopped working at the end of that month. Rabbit's $199 R1 made a similar pitch in 2024. Meta has looked at the category up close, too. In December 2025 it bought Limitless, which made a $99 pendant that recorded your conversations, and Limitless stopped selling the pendant. Meta said at the time the deal would help it "accelerate our work to build AI-enabled wearables." Zuckerberg didn't say tonight whether Charm came out of that team.

Why Meta wants a charm

Meta's hardware bet has been glasses for years, and tonight was mostly more of that. Plenty of people don't want a computer on their face, though, and plenty more already wear prescription frames they like. Right now Muse lives in an app on your phone and your Mac. A Charm gives Meta a Muse device for everyone who won't buy glasses, and unlike your phone, it's hardware Meta controls.

Charm also starts with an advantage Humane never had. Humane had to build the device and the AI at the same time. Muse already exists, already sends email and shops on your behalf, and CNBC reported this week that its downloads are surging. The Charm only has to be a good front door. That's a lower bar, but it's still a high one for a device Zuckerberg says isn't finalized three months before it's due, from a company that has built only a handful. It also hangs an agent that can spend your money off your keychain, and Engadget's Devindra Hardawar was already joking that Muse Charm "will be invading your privacy soon."

Before December, Meta owes buyers three answers: what it costs, whether it needs your phone, and what it does that the Muse app on that phone can't.
