React Based Responsive Ui With Component Composition

via “composable chat ui component primitives with headless architecture”

Typescript/React Library for AI Chat💬🚀

Unique: Uses a primitive-based architecture where components are unstyled building blocks composed via React context, rather than pre-styled component libraries. This enables zero style conflicts and maximum customization while maintaining a shared state management layer (@assistant-ui/store) that handles message threading, streaming, and tool execution logic.

vs others: More flexible than Vercel AI SDK's pre-built components and more opinionated than raw React, striking a balance for teams that need customization without building from scratch.
