Meta Launches Custom Spaces in Muse AI App for Personalized Experiences

Meta has introduced Custom Spaces within its Muse AI app, allowing users to create and configure persistent, personalized AI-powered environments tailored to specific use cases or workflows. The feature moves Muse beyond a single-interface AI assistant toward a modular, context-aware product where different spaces can be configured for different tasks or roles. For developers watching the AI app layer, this represents Meta's bet on personalized AI surfaces as the dominant consumer interaction model going forward. The Current Muse model underlying the app has scored 47% on Meta's own Personal Superintelligence Index, giving a concrete capability anchor for what these spaces can currently deliver. Teams building consumer AI products should study the spaces paradigm as a UI/UX pattern that may define user expectations for AI app personalization.
