`<CopilotTextarea>` is a React component that acts as a drop-in replacement for the standard `<textarea>`,
 offering enhanced autocomplete features powered by AI. It is context-aware, integrating seamlessly with the
[`useCopilotReadable`](/reference/v1/hooks/useCopilotReadable) hook to provide intelligent suggestions based on the application context.
 
In addition, it provides a hovering editor window (available by default via `Cmd + K` on Mac and `Ctrl + K` on Windows) that allows the user to
suggest changes to the text, for example providing a summary or rephrasing the text.
 
## Example
 
```tsx
import { CopilotTextarea } from '@copilotkit/react-textarea';
import "@copilotkit/react-textarea/styles.css";
 
<CopilotTextarea
  autosuggestionsConfig={{
    textareaPurpose:
     "the body of an email message",
    chatApiConfigs: {},
  }}
/>
```
 
## Usage
 
### Install Dependencies
 
This component is part of the [@copilotkit/react-textarea](https://npmjs.com/package/@copilotkit/react-textarea) package.
 
```shell npm2yarn \"@copilotkit/react-textarea"\
npm install @copilotkit/react-core @copilotkit/react-textarea
```
 
### Usage
 
Use the CopilotTextarea component in your React application similarly to a standard `<textarea />`,
with additional configurations for AI-powered features.
 
For example:
 
```tsx
import { useState } from "react";
import { CopilotTextarea } from "@copilotkit/react-textarea";
import "@copilotkit/react-textarea/styles.css";
 
export function ExampleComponent() {
  const [text, setText] = useState("");
 
  return (
    <CopilotTextarea
      className="custom-textarea-class"
      value={text}
      onValueChange={(value: string) => setText(value)}
      placeholder="Enter your text here..."
      autosuggestionsConfig={{
        textareaPurpose: "Provide context or purpose of the textarea.",
        chatApiConfigs: {
          suggestionsApiConfig: {
            maxTokens: 20,
            stop: [".", "?", "!"],
          },
        },
      }}
    />
  );
}
```
 
### Look & Feel
 
By default, CopilotKit components do not have any styles. You can import CopilotKit's stylesheet at the root of your project:
```tsx title="YourRootComponent.tsx"
...
import "@copilotkit/react-textarea/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](/guides/custom-look-and-feel/customize-built-in-ui-components) guide.
