Meta's Muse Can Now Talk — and Build You Custom Apps

 

Meta's personal AI agent Muse just learned two new tricks. On November 5, Muse Voice rolled out to every user in the United States — real-time voice conversations with an expressive animated avatar. A day later, Meta added Spaces, a feature that turns a plain description into a working app-like hub.

Talk to Muse — It Talks Back

Muse Voice lets you speak to your agent instead of typing. Tap the phone icon in the top-right corner of the Muse app and the conversation starts — you can interrupt it mid-sentence, just like talking to a person. The avatar reacts with expressions and gestures that match the conversation's tone, and there are hundreds of voices to choose from. Run it voice-only, avatar beside your chat, or full-screen.

Two new models power it — Muse Realtime Voice and Muse Realtime Avatar — keeping speech, lip movement and gestures in sync. The Verge's hands-on found replies quick, with occasional pauses while Muse looked something up. Live now on mobile, web and Mac — US only, 18 and over. Voice reaches Meta's AI glasses and the Muse Charm wearable later; no dates for other countries yet.

One honest note: voice isn't brand new — Meta previewed it at Connect in September and some users got it from October 24. November 5 is the day it reached every US user.

Spaces: Describe It, Muse Builds It

Spaces is the newer of the two. Describe an idea in chat — a gift tracker, a wedding planner, a vacation plan — and Muse builds a custom space for it: a tracker, a planner, a dashboard, even a game. It lives in the sidebar, so you can jump back in any time.

The clever part: spaces stay current on their own. Connect Gmail, Google Calendar, OpenTable or Notion, and new concert dates, price changes or savings progress show up without you asking. Mark Zuckerberg posted that he's already made a BBQ game, an event tracker and a home control dashboard with it.

Spaces roll out to all Muse users now, alongside a specialized version of Meta's "Muse Wonder" model.

Why It Matters

Muse is growing fast. Zuckerberg said on Meta's October earnings call that Muse agents already had 10 million users in the US and Canada — less than two months after debut. Voice and Spaces are Meta's answer to the obvious question — what keeps people coming back once the novelty wears off? Talking to your agent — and having it build things for you — beats another chat window.

The race is crowded. OpenAI has "Dots", its own always-on agent with a cartoon persona, and SpaceXAI has Grokbot. Meta's bet: the agent that builds your apps for you is harder to leave than one that just answers questions. Meta already pitched Muse for Small Business in September.

Voice makes Muse feel like a person; Spaces makes it feel like a coworker. Both are free and live now in the US — worth trying, just don't expect voice outside the US yet. The agent wars are officially a voice-and-build contest now.
