Meta Lets Muse Users Build Custom Mini Apps Called Spaces by Describing Them

Users describe what they want and Muse assembles it as a dedicated interface inside the app, with no coding required, Meta said when it announced the feature on November 6. A Space can then be changed by asking Muse to add missing elements, alter its appearance or adjust how it works. Meta described each one as a "custom experience built around a user's interests and daily routine" and said Spaces are "now available everywhere Muse is available."

The launch extends Muse from a chat-style agent into something closer to a personal software platform. Once users connect the apps and services they rely on, Spaces keep updating in the background with information such as price changes or progress towards a savings goal, according to Meta. They can be pinned to the sidebar or main tabs, hidden, or scheduled to appear at set times, so that a weekday planner gives way to weekend plans on Saturday.

Meta's suggested uses include a trivia game, trip planner, shopping hub, music tracker, school dashboard, wedding planner, podcast studio, order tracker and client hub. Alex Cornell, a product designer on Muse, described Spaces as dedicated commands turned into their own interface so they are easy to return to for ongoing tracking, Social Media Today reported. Chief executive Mark Zuckerberg wrote on X: "tell Muse what you need and it builds it," adding that he had made a barbecue game, an event tracker and a home control dashboard. Social Media Today reported that one of his Spaces controls the vents on his meat smoker over Bluetooth.

Alongside Spaces, Meta is rolling out models for Meta AI and Muse trained on what it learned from its Muse Wonder models, which it says are better at retaining context and recovering when a task runs into problems. It has also expanded memory in both assistants for more personalised answers.

The idea is not new. Google announced Opal, which lets people create mini apps with AI, more than a year ago and later added similar features to Google AI Studio, while services such as Replit let users generate and publish their own apps. Meta's version differs in that Spaces live only inside Muse and draw on the accounts users connect to it.

The feature is also a bid to give people reasons to return. Meta has said Muse has passed 10 million downloads and that shopping is its main use, but Sensor Tower analysis cited by Social Media Today shows retention falling sharply about two weeks after users install the app.
