Meta announced on November 6 that Spaces are now available everywhere Muse is available. Describe an idea to Muse and it builds a persistent, customised experience inside the app — a holiday gift tracker, a daily word game, a DIY planning board — that you can keep refining by asking Muse to add pieces, change the look or tweak how it works.

Spaces live in the app itself: you can pin them to the sidebar or main tabs, hide them, or schedule when they appear, so a weekly planner can show during the workweek and give way to weekend plans on Saturday. Meta's examples run from shopping hubs and music trackers to school dashboards, wedding planners, order trackers and freelance client hubs.

Connected apps let a Space update in the background with price changes, new concert dates or savings progress, and you can check off items and edit directly inside it. Mark Zuckerberg said he had built a BBQ game, an event tracker and a home control dashboard this way. Sharing and collaborative Spaces are still under exploration, so the launch is centred on individual use.
