A chatbot panel component for the CopilotKit framework. The component allows for a high degree of customization through various props and custom CSS.

Install Dependencies

This component is part of the @copilotkit/react-ui package.

npm install @copilotkit/react-core @copilotkit/react-ui

Usage

import { CopilotChat } from "@copilotkit/react-ui";
import "@copilotkit/react-ui/styles.css";
 
<CopilotChat
  labels={{
    title: "Your Assistant",
    initial: "Hi! 👋 How can I assist you today?",
  }}
/>

With Observability Hooks

To monitor user interactions, provide the observabilityHooks prop. Note: This requires a publicApiKey in the <CopilotKit> provider.

<CopilotKit publicApiKey="YOUR_PUBLIC_API_KEY">
  <CopilotChat
    observabilityHooks={{
      onMessageSent: (message) => {
        console.log("Message sent:", message);
      },
    }}
  />
</CopilotKit>

Look & Feel

By default, CopilotKit components do not have any styles. You can import CopilotKit's stylesheet at the root of your project:

...
import "@copilotkit/react-ui/styles.css"; // [!code highlight]
 
export function YourRootComponent() {
  return (
    <CopilotKit>
      ...
    </CopilotKit>
  );
}

For more information about how to customize the styles, check out the Customize Look & Feel guide.

Properties

Custom instructions to be added to the system message. Use this property to provide additional context or guidance to the language model, influencing its responses. These instructions can include specific directions, preferences, or criteria that the model should consider when generating its output, thereby tailoring the conversation more precisely to the user's needs or the application's requirements. Controls the behavior of suggestions in the chat interface.

auto (default) - Suggestions are generated automatically: - When the chat is first opened (empty state) - After each message exchange completes - Uses configuration from useCopilotChatSuggestions hooks

manual - Suggestions are controlled programmatically: - Use setSuggestions() to set custom suggestions - Use generateSuggestions() to trigger AI generation - Access via useCopilotChat hook

SuggestionItem[] - Static suggestions array: - Always shows the same suggestions - No AI generation involved

A callback that gets called when the in progress state changes. A callback that gets called when a new message it submitted. A custom stop generation function. A custom reload messages function. A callback function to regenerate the assistant's response A callback function when the message is copied A callback function for thumbs up feedback A callback function for thumbs down feedback A list of markdown components to render in assistant message. Useful when you want to render custom elements in the message (e.g a reference tag element) Icons can be used to set custom icons for the chat window. Labels can be used to set custom labels for the chat window. Configuration for file attachments in the chat input. Enables users to attach images, audio, video, and documents.

@example

<CopilotChat
  attachments={{
    enabled: true,
    accept: "image,application/pdf",
    maxSize: 10  1024  1024, // 10MB
    onUpload: async (file) => {
      const url = await uploadToS3(file);
      return { url, mimeType: file.type };
    },
  }}
/>

A function that takes in context string and instructions and returns the system message to include in the chat request. Use this to completely override the system message, when providing instructions is not enough. Disables inclusion of CopilotKit’s default system message. When true, no system message is sent (this also suppresses any custom message from makeSystemMessage). A custom assistant message component to use instead of the default. A custom user message component to use instead of the default. A custom error message component to use instead of the default. A custom Messages component to use instead of the default. A custom RenderMessage component to use instead of the default.

Warning: This is a break-glass solution to allow for custom rendering of messages. You are most likely looking to swap out the AssistantMessage and UserMessage components instead which are also props.

A custom suggestions list component to use instead of the default. A custom Input component to use instead of the default. A class name to apply to the root element. Children to render. Event hooks for CopilotKit chat events. These hooks only work when publicApiKey is provided. Custom error renderer for chat-specific errors. When provided, errors will be displayed inline within the chat interface. Optional handler for comprehensive debugging and observability.
