A design system for AI model interactions. Components come with use case instructions built in, are built on Material Design 3 and styled by your design tokens, and run on Fal.ai, OpenRouter or your own engine.
Chai UI is an AI-native design system built from the ground up with intelligent components and patterns for advanced AI interactions. It provides interfaces for model routing, media detection, and prompt optimization, enabling designers, developers, and AI agents to build apps more easily. The system includes components, tokens, and packages, with a prompt bar example using the Composer component from @chai-ui/react. It is currently in active development and available as a private preview.
