Muse Spaces: what it is and how to use it

Muse Spaces are small custom apps you build inside Meta's Muse by describing them in chat: a gift tracker, a trip planner, a client hub. To use one, tell Muse what you need, let it build the space, then pin it to your sidebar or main tabs and keep editing it by asking for changes.

The posts that launched it

On Friday, @finkd posted that he had been "playing around with spaces in Muse," summing it up as "tell Muse what you need and it builds it." Zuckerberg said he made a BBQ game, an event tracker and a home control dashboard, and attached three images.

Meta's own announcement the same day calls a space "a custom experience you create inside Muse by describing your idea." Meta says spaces are available "everywhere Muse is available," starting now.

The day before, Meta shipped a different Muse feature. @AIatMeta said Muse Realtime Avatar, first previewed at Connect, is rolling out in the Muse app in the US, turning voice chats into "expressive, interactive avatars." @alexandr_wang posted that Muse Voice is out for everyone in the US and that you can now phone call and video chat with your Muse. So in two days Meta pushed Muse in two directions at once: you can talk to it now, and you can build things with it.

How to use Muse Spaces

Meta's post doesn't give a button-by-button path, but it does describe the flow:

1. Open Muse and describe the space you want in a normal chat message.
2. Muse builds it. Then keep asking for changes, whether that's "adding what's missing, trying a new look, or changing how it works."
3. Put it where you'll see it. You can add spaces to the sidebar, move them into your main tabs, hide the ones you don't need, and schedule when each one appears. Meta's example is a weekly planner that shows up on workdays and gets swapped for weekend plans on Saturday.
4. Connect the apps you use so the space updates itself in the background. You can check items off, add notes and edit inside the space.

Here are three starter prompts of my own, small enough to judge in a few minutes:

• "Build a holiday gift tracker with columns for person, idea, budget, and bought yes or no."
• "Make a weekly job board for my side business: client, address, date, and paid or unpaid."
• "Create a trip planner for a three-day Chicago weekend with a packing list and a daily schedule."

What it can do so far

Those are the only connections Meta names. TechCrunch's write-up adds examples such as concert dates, price changes and savings progress staying current in the background.

Some things are missing. The announcement gives no price or plan limit for Spaces. For what Muse itself costs, see our post on Muse coming to the Mac. Sharing isn't here yet either: Meta says it is "exploring ways for you to share your spaces with others," and describes spaces as "personal from the start." For now, only the person who built a space can use it.

My read

Spaces moves Muse toward the same idea as Cursor Build Live Apps: describe the tool and the AI builds it. The audience is different, though. Cursor targets people who ship web apps. Muse targets people who would never open a code editor and just want a working list that keeps itself up to date.

The Marketplace detail is the interesting one for business owners. A space that reads your listings and buyer messages is a small CRM built in a chat window. Meta already opened Muse to business data with connectors for QuickBooks, Shopify and Stripe, and Spaces is the obvious place for that data to show up. Meta hasn't said whether those connectors feed spaces, so test it before you count on it.

I'd keep two cautions in mind. A tracker only one person can see can't run a team's workflow, so until sharing ships, anything important still needs a home your staff can open too. And when a space updates itself in the background, check what it pulled before you act on it.

What this means for businesses

Anyone with Muse can now get a personal dashboard by asking for one. The harder decisions come after that: which data each tool gets to see, and where the official record lives when a chat-built tracker and your real system disagree.
