Meta lets Muse users build custom AI app experiences called spaces

What are Spaces?

Meta has launched Spaces, a new feature for its Muse AI assistant that lets users build customized, app-like experiences directly inside the Muse interface. Instead of switching between separate apps for different tasks, users can create dedicated Spaces for each project, and Muse works toward that specific goal within each Space.

TechCrunch described Spaces as breakout conversations that revolve around a particular topic, while Meta refers to them as custom experiences. They live in the sidebar of the Muse interface, and clicking on a Space brings up a dedicated workspace where Muse helps with that task.

In September, Meta launched Muse as a personal AI agent available across iOS, Android, and the web. The company said in its October earnings call that Muse had already reached 10 million users in the U.S. and Canada, less than two months after launching.

• Describe a project in chat and Muse builds a dedicated Space for it, whether that is a tracker, planner, or project board.
• Examples Meta gives include a holiday gift tracker, wedding planner, vacation itinerary organizer, recipe collection for an event, school dashboard, or music tracker.
• Spaces can be moved in the sidebar, pinned to the main tab, or scheduled to appear on certain days.

How do Spaces integrate with other apps?

Spaces can be connected to third-party apps and data sources, and Meta says they keep themselves updated in the background. New concert dates, price changes, or savings progress show up without the user having to ask. The background sync means a shopping Space can track price drops on saved items, while a trip planner can monitor hotel rates and flight changes automatically.

The Verge reported that users can check items off, add notes, and make edits directly within each Space, turning them into living documents that evolve with the project. Users can schedule when specific Spaces appear or swap them based on the day of the week, keeping a weekly planner visible during workdays and swapping it for weekend plans on Saturday.

Meta is also exploring ways to let users share their Spaces with others and collaborate on them, though that feature is not yet available.

Zuckerberg shows off Spaces with a BBQ game

Meta founder and CEO Mark Zuckerberg posted about the new feature on X on Friday, November 6. He wrote that he had been playing around with Spaces and built a BBQ game, an event tracker, and a home control dashboard. He said he was excited to see what users build.Zuckerberg's posts about Muse on X

Spaces is the second new Muse feature this week

Spaces follows Muse Voice, which Meta launched on Thursday, November 5. Voice allows users to video chat with their Muse agent and give it commands verbally. The rapid pace of new features indicates Meta is investing heavily in making Muse a daily-use product rather than a novelty.

The company is competing against other AI assistants with personality-driven interfaces, including OpenAI's dots and SpaceXAI's Grokbot, both of which also launched with character-driven personas. During Meta's October earnings call, Zuckerberg said Muse had 10 million users in the U.S. and Canada, less than two months after its September launch. The company has not disclosed international rollout plans beyond North America.

The Spaces rollout is accompanied by a specialized version of the Muse Wonder AI model, which Meta says is optimized for the kind of task tracking and persistent state management Spaces require. For more on Meta's AI strategy, read our earlier coverage of AI stocks after the midterm election.
