description: "Angular provider that overrides the default text labels used by the CopilotKit chat components"
---

## Overview

`provideCopilotChatLabels` returns an Angular [`Provider`](https://angular.dev/guide/di/dependency-injection-providers) that customizes the text labels used throughout the prebuilt chat components, such as the input placeholder, toolbar button labels, the disclaimer text, and the welcome message. You pass a partial set of labels and they are merged over the defaults, so you only override the strings you want to change.

Add it to an application or component `providers` array. Components read the merged labels through [`injectChatLabels`](/reference/angular/functions/injectChatLabels). This mirrors React's chat label configuration via `useCopilotChatConfiguration`.

The full set of defaults lives in `COPILOT_CHAT_DEFAULT_LABELS`. Any field you omit falls back to its default value.

## Signature

```ts
import { provideCopilotChatLabels } from "@copilotkit/angular";
import type { Provider } from "@angular/core";

function provideCopilotChatLabels(
  config: Partial<CopilotChatLabels>,
): Provider;
```

## Return Value

Returns an Angular `Provider` that binds the merged labels to the `COPILOT_CHAT_LABELS` injection token.

## Usage

Override a few labels in your application config. Everything you do not list keeps its default.

```ts title="src/app/app.config.ts"
import { ApplicationConfig } from "@angular/core";
import {
  provideCopilotKit,
  provideCopilotChatLabels,
} from "@copilotkit/angular";

export const appConfig: ApplicationConfig = {
  providers: [
    provideCopilotKit({ runtimeUrl: "/api/copilotkit" }),
    provideCopilotChatLabels({
      chatInputPlaceholder: "Ask me anything...",
      welcomeMessageText: "Welcome! What can I help you build?",
    }),
  ],
};
```

You can also scope labels to part of your app by adding the provider to a feature component's `providers` array instead of the application config.
