--- ## 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 https://github.com/user-attachments/assets/72b7b4f3-b6e7-460c-a932-5746fe3c8db3

**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. 👉 **[Request early access →](https://go.copilotkit.ai/beyond-the-web-form)** ## 🧠 Self-Learning Agents Improve your procuct 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. 👉 **[Request early access →](https://go.copilotkit.ai/beyond-the-web-form)** 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. ![CopilotKit Diagram — Motion x2 6 sec version](https://github.com/user-attachments/assets/6f175d86-bd22-4c26-a13a-6013654ed542) 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

{agent.state.city}
