Meta describes Spaces as "custom experiences" that live in the sidebar of the interface where users interact with their Muse agent. Clicking on a Space opens the conversation, where Muse works towards a particular goal on the user's behalf, such as planning a vacation, tracking holiday gifts, collecting recipes for a family event, or creating a space for DIY projects.
The launch is the second new Muse feature in the past week. On Thursday, Meta announced Muse Voice, which lets users video chat with their agent and give it commands verbally. Muse agents made their debut less than two months before Meta chief executive Mark Zuckerberg said in October that they had 10 million users in the U.S. and Canada.
"Describe an idea in chat, and Muse builds a space for you, whether that's a tracker, a planner or a project board," Meta says. The company also says Spaces can be integrated with third-party apps: "Connect the apps you use, and your spaces keep themselves up to date in the background, so new concert dates, price changes, or savings progress show up without you having to ask."
On Friday, Zuckerberg posted on X about the feature, saying he had made a BBQ game, an event tracker and a home control dashboard, and that he was excited to see what people build.
The agents, with their cuddly avatars, have drawn a relatively warm reception since their debut. Meta is competing with other AI agents built around similarly cartoonish personas, including OpenAI's dots and SpaceXAI's Grokbot.
