Aigui

npm npm downloads CI License: MIT

Render a streaming LLM answer as live UI — markdown, charts, diagrams, maths, 3D, topologies and app-defined cards — in React, Vue or plain DOM.

Live demos · Use it from Claude Code or Codex — the agent draws charts, diagrams, 3D and topologies for you, as pictures or a live page: install the plugin.

Every picture above was drawn by AIGUI from a fenced block a model wrote; the data is sample data.

Install

pnpm add @ai-gui/core @ai-gui/react      # or @ai-gui/vue, @ai-gui/vanilla
pnpm add @ai-gui/plugin-chart @ai-gui/plugin-mermaid @ai-gui/plugin-katex   # any plugins

Quick start

import { useRef } from "react"
import { buildSystemPrompt } from "@ai-gui/core"
import { AIRenderer } from "@ai-gui/react"
import { chart } from "@ai-gui/plugin-chart"
import { mermaid } from "@ai-gui/plugin-mermaid"

const plugins = [chart(), mermaid()]
const system = buildSystemPrompt({ base: "You are a helpful assistant.", plugins })

export function Answer() {
  const ref = useRef(null)
  async function ask(question: string) {
    const res = await fetch("/api/chat", { method: "POST", body: JSON.stringify({ system, question }) })
    ref.current.reset()
    await ref.current.feed(res.body) // renders as the tokens arrive
  }
  return <AIRenderer ref={ref} plugins={plugins} />
}

buildSystemPrompt tells the model which blocks it may write; pass locale: "zh-CN" for the rules in Chinese. The backend only streams text — any language works.

In Claude Code and Codex

# Claude Code
/plugin marketplace add liliang-cn/aigui
/plugin install aigui@aigui

# Codex
codex plugin marketplace add liliang-cn/aigui
codex plugin add aigui@aigui

The agent can then draw: aigui_render returns PNGs, aigui_open opens a live page in your browser, aigui_edit changes a page in place, aigui_export saves it as PNG, PDF, a self-contained HTML file or a GIF/WebM of it playing, and aigui_topology draws a system straight from its docker-compose or Kubernetes files. Page text is English unless you ask for another language. See @ai-gui/mcp.

To see the pictures inside Claude Code instead of an image viewer, add the img-view mod: /plugin install img-view@aigui. It shows each drawing in a pane beside the conversation, as real pixels in kitty, Ghostty, iTerm2 and WezTerm and as colour block art in any other terminal.
