Meta introduces Spaces, a new way to collaborate with your Muse agent

Meta has introduced Spaces, a new way to communicate and work with its Muse agents, the agentic helpers the company launched in recent months. Spaces are essentially breakout conversations centered on a single topic — Meta calls them "custom experiences" — and they appear in the sidebar of the interface where users interact with their Muse agent. Clicking a Space opens its conversation, where Muse works toward a defined goal on the user's behalf.

The use cases Meta highlights are everyday project work: a vacation-planning Space, a recipe-collection tab for a family event, a holiday gift tracker, a wedding planner, or a space for DIY projects. The company frames Spaces as generative rather than templated, saying users can "describe an idea in chat, and Muse builds a space for you, whether that's a tracker, a planner or a project board." Mark Zuckerberg posted on X about his own use: "Playing around with spaces in Muse lately — tell Muse what you need and it builds it. I've made a BBQ game, an event tracker, and a home control dashboard. Excited to see what you build."

Meta also says Spaces can connect to third-party apps and data, with the spaces refreshing themselves in the background so items like new concert dates, price changes or savings progress appear without a prompt. That positions Spaces less as a chat window and more as a persistent, self-updating workspace layered on top of the agent.

Spaces is the second Muse feature debuting in a single week: on Thursday, Meta announced Muse Voice, which lets users video-chat with their agent and issue verbal commands. The rollout comes as Muse gains traction — during Meta's October earnings call, Zuckerberg said the agents had 10 million users in the U.S. and Canada, under two months after they debuted.

Meta's agents, and the cuddly avatars wrapping them, compete with similarly cartoonish rivals, including OpenAI's dots and SpaceXAI's Grokbot, introduced with comparable personas. What to watch: whether Spaces' background app sync holds up as users connect more third-party services, whether the sidebar-based model scales past a handful of concurrent projects, and whether the rapid feature cadence — two launches in a week — translates into retention beyond the 10 million early users Meta has reported.
