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.

shell

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

Usage

tsx

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.

tsx

<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:

tsx

...
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.

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 </PropertyReference>

<PropertyReference name="onInProgress" type="(inProgress: boolean) => void" > A callback that gets called when the in progress state changes. </PropertyReference> <PropertyReference name="onSubmitMessage" type="(message: string) => void | Promise<void>" > A callback that gets called when a new message it submitted. </PropertyReference> <PropertyReference name="onStopGeneration" type="OnStopGeneration" > A custom stop generation function. </PropertyReference> <PropertyReference name="onReloadMessages" type="OnReloadMessages" > A custom reload messages function. </PropertyReference> <PropertyReference name="onRegenerate" type="(messageId: string) => void" > A callback function to regenerate the assistant's response </PropertyReference> <PropertyReference name="onCopy" type="(message: string) => void" > A callback function when the message is copied </PropertyReference> <PropertyReference name="onThumbsUp" type="(message: Message) => void" > A callback function for thumbs up feedback </PropertyReference> <PropertyReference name="onThumbsDown" type="(message: Message) => void" > A callback function for thumbs down feedback </PropertyReference> <PropertyReference name="markdownTagRenderers" type="ComponentsMap" > A list of markdown components to render in assistant message.

@example

tsx

<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 };
    },
  }}
/>

</PropertyReference> <PropertyReference name="makeSystemMessage" type="SystemMessageFunction" > 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. </PropertyReference> <PropertyReference name="disableSystemMessage" type="boolean" > Disables inclusion of CopilotKit’s default system message. When true, no system message is sent (this also suppresses any custom message from <code>makeSystemMessage</code>). </PropertyReference> <PropertyReference name="AssistantMessage" type="React.ComponentType<AssistantMessageProps>" > A custom assistant message component to use instead of the default. </PropertyReference> <PropertyReference name="UserMessage" type="React.ComponentType<UserMessageProps>" > A custom user message component to use instead of the default. </PropertyReference> <PropertyReference name="ErrorMessage" type="React.ComponentType<ErrorMessageProps>" > A custom error message component to use instead of the default. </PropertyReference> <PropertyReference name="Messages" type="React.ComponentType<MessagesProps>" > A custom Messages component to use instead of the default. </PropertyReference> <PropertyReference name="RenderMessage" type="React.ComponentType<RenderMessageProps>" > 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. </PropertyReference>
