Prompt-kit is a React-based toolkit and component library specialized for building conversational interfaces for large language models. It provides a framework of reusable UI elements designed to handle the specific requirements of generative AI, such as streaming text responses, rendering model reasoning, and managing complex model outputs.
The toolkit distinguishes itself through specialized visualization capabilities, including the rendering of chain-of-thought reasoning traces and the display of external tool interactions. It also features an interactive preview system that renders generated code strings as live, active components.
The library covers a broad range of interface needs, including chat containers with auto-scrolling and message bubbles, drag-and-drop file upload systems, and markdown transformation for rich text rendering. It also includes systems for RAG source attribution with clickable citations and user feedback mechanisms for evaluating response quality through ratings and reactions.
