prompt-kit provides prebuilt UI primitives tailored for AI chat interfaces, agents, and autonomous assistants. Designed for React, Next.js, and Tailwind CSS, components can be added directly into projects using the shadcn CLI. It includes purpose-built blocks for streaming responses, collapsible tool calls, feedback bars, and chain-of-thought displays.

What it's for

  • Add ready-made chat UI blocks with tool-calling support to Next.js apps
  • Display collapsible execution steps and function-call statuses in AI assistants
  • Render chain-of-thought reasoning and thinking states in generative AI products

Features

  • Installable via the shadcn CLI registry (npx shadcn@latest add prompt-kit/[component])

  • Chain-of-thought and thinking-bar UI components
  • Built with React, Next.js, and Tailwind CSS

Why it was saved

  • @shadcn, 6 August 2025: The author (@shadcn) highlights that a working chatbot with tool calls is one npx command away; the video demonstrates the result: a clean chat UI streaming answers and showing collapsible tool-call chips (tool-getTime, completed) that fetch current time for cities.
