## What is CopilotKit
|
||
|
||
CopilotKit is a best-in-class SDK for building full-stack agentic applications, Generative UI, and chat applications.
|
||
|
||
What started as a React library is now a **multi-platform agentic framework**: the same agent can power your web app, your mobile app, and your team's Slack workspace.
|
||
|
||
We are the company behind the **[AG-UI Protocol](https://github.com/ag-ui-protocol/ag-ui)** - adopted by Google, LangChain, AWS, Microsoft, Mastra, PydanticAI, and more!
|
||
|
||
## Quick Start
|
||
|
||
Up and running in under five minutes. All you need is an LLM key (OpenAI, Anthropic, Gemini, etc.).
|
||
|
||
```bash
|
||
npx copilotkit@latest create
|
||
```
|
||
|
||
## Agent Skills
|
||
|
||
CopilotKit ships [agent skills](https://docs.copilotkit.ai) that teach your coding agent (Claude Code, Codex, Cursor, Gemini, and others) how to set up, build with, integrate, debug, and upgrade CopilotKit.
|
||
|
||
Install them into any project directory:
|
||
|
||
```bash
|
||
npx copilotkit@latest skills install
|
||
```
|
||
|
||
Run it again any time to refresh to the latest skills.
|
||
|
||
## Bring Your App to Life

|
||
<div align="center"> Add AI to your app in 1 minute</div>
|
||
|
||
**Features:**
|
||
|
||
- **Chat UI** – A fully customizable chat interface that supports message streaming, tool calls, and agent responses.
|
||
- **Backend Tool Rendering** – Enables agents to call backend tools that return UI components rendered directly in the client.
|
||
- **Generative UI** – Allows agents to generate and update UI components dynamically at runtime based on user intent and agent state.
|
||
- **Shared State** – A synchronized state layer that both agents and UI components can read from and write to in real time.
|
||
- **Human-in-the-Loop** – Lets agents pause execution to request user input, confirmation, or edits before continuing.
|
||
- **Self-Learning** _(early access)_ – Agents that continuously improve from user feedback via in-context reinforcement learning (CLHF).
|
||
|
||
## 🧩 Works With Your Stack
|
||
|
||
One agent backend. Every frontend.
|
||
|
||
| Platform | Status | Get Started |
|
||
| ------------------------------------------- | ------------ | ----------------------------------------------------------------------------------------------------------- |
|
||
| ⚛️ React / Next.js | ✅ GA | [Quickstart](https://docs.copilotkit.ai/built-in-agent/quickstart) |
|
||
| 🅰️ Angular | ✅ Supported | [Source Code - Quickstart coming soon](https://github.com/CopilotKit/CopilotKit/tree/main/packages/angular) |
|
||
| 💚 Vue | ✅ Supported | [Source Code - Quickstart coming soon](https://github.com/CopilotKit/CopilotKit/tree/main/packages/vue) |
|
||
| 📱 React Native | ✅ Supported | [Quickstart](https://docs.copilotkit.ai/react-native) |
|
||
| 💬 Slack / MS Teams / Discord / Google Chat | 🟡 Beta | [Request early access](https://go.copilotkit.ai/beyond-the-web-form) |
|
||
|
||
Your agent logic stays the same — AG-UI handles the wire protocol, CopilotKit handles the UI layer for each framework.
|
||
|
||
## 💬 Beyond the Browser: Slack & Microsoft Teams (Discord, Google Chat coming soon...)
|
||
|
||
Your agents can run and generate Generative UI beyond the web app (**[Learn more](https://www.copilotkit.ai/integrations)**).
|
||
|
||
CopilotKit now lets you deploy the **same agent** to the places your users already work:
|
||
|
||
- **Slack** – Agents as first-class Slack apps: threads, tool calls, and human-in-the-loop approvals right in the channel.
|
||
- **Microsoft Teams** – Bring agentic workflows to the enterprise, where your org already lives.
|
||
|
||
🔒 **Early access:** We're onboarding teams now.
|
||
|
||

|
||
|
||
## 🧠 Self-Learning Agents
|
||
|
||
Improve your product by learning over time.
|
||
|
||
With **Continuous Learning from Human Feedback (CLHF)**, part of the [CopilotKit Intelligence Platform](https://www.copilotkit.ai/copilotkit-intelligence), agents improve with every interaction:
|
||
|
||
- **In-context reinforcement learning** – Agents automatically improve from user interactions, no model fine-tuning required.
|
||
- **Automatic prompt augmentation** – Agent behavior adapts based on recent interactions and outcomes.
|
||
- **Per-user adaptation** – Agents learn individual preferences and get better for each user over time.
|
||
- **Threads & persistence** – Full interaction history — generative UI, human-in-the-loop, shared state — captured across sessions.
|
||
|
||
Available via CopilotKit Cloud or self-hosted.
|
||
|
||
🔒 **Early access:** We're onboarding teams now.

||
https://github.com/user-attachments/assets/7372b27b-8def-40fb-a11d-1f6585f556ad
|
||
|
||
What this gives you:
|
||
|
||
- **CopilotKit installed** – Core packages are fully set up in your app
|
||
- **Provider configured** – Context, state, and hooks ready to use
|
||
- **Agent <> UI connected** – Agents can stream actions and render UI immediately
|
||
- **Deployment-ready** – Your app is ready to deploy
|
||
|
||
[Complete getting started guide →](https://docs.copilotkit.ai/langgraph/quickstart)
|
||
|
||
## How it works:
|
||
|
||
CopilotKit connects your UI, agents, and tools into a single interaction loop.
|
||
|
||
|
||
|
||
This enables:
|
||
|
||
- Agents that ask users for input
|
||
- Tools that render UI
|
||
- Stateful workflows across steps and sessions
|
||
- One agent, deployed across web, mobile, and chat platforms
|
||
|
||
## ⭐️ useAgent Hook
|
||
|
||
The `useAgent` hook sits directly on AG-UI, giving you full programmatic control over the agent connection.
|
||
|
||
```ts
|
||
// Programmatically access and control your agents
|
||
const { agent } = useAgent({ agentId: "my_agent" });
|
||
|
||
// Render and update your agent's state
|
||
return <div>
|
||
<h1>{agent.state.city}</h1>
|
||
<button onClick={() => agent.setState({ city: "NYC" })}>
|
||
Set City
|
||
</button>
|
||
</div>
|
||
```
|
||
|
||

|
||
|
||
## Generative UI
|
||
|
||
Generative UI is a core CopilotKit pattern that allows agents to dynamically render UI as part of their workflow.
