tool-ui

Why we included this project

Most chat apps that let an LLM call tools end up dumping raw JSON into the conversation, which is hard for users to read and act on. Tool UI fixes that with copy/paste React components that render tool payloads as approval cards, forms, tables, charts, and multi-step question flows. The components follow the shadcn/ui model, so they live in your codebase instead of pulling in a locked dependency, and each one has a Zod schema that validates the tool output before rendering, failing safely when the payload doesn't match. User choices made in the UI flow back to the assistant and persist as receipts, so the widgets are interactive rather than just displays. It is built by the assistant-ui team and works in any React chat app that needs structured, human-readable rendering of tool calls.
