## Link Preview

The Link Preview extension shows a preview of the web page for every link in your message. Returns raw metadata that you can style however you want.

**When to use:** You want full control over how link previews look in your app.

<Note>
  **Out-of-the-box in:** [UI Kit Builder](/chat-builder/react/features) ✅ | [Widget Builder](/widget/html/features) ✅ | [UI Kits](/ui-kit/react/extensions#link-preview) ✅ | [SDK](/sdk/javascript/overview) ✅
</Note>

<Note>
  If you want a ready-to-render preview card, use [Rich Media Preview](#rich-media-preview).

### Extension settings

<Steps>
  <Step title="Open your CometChat app">
    Login to [CometChat](https://app.cometchat.com/login) and select your app.
  </Step>

  <Step title="Enable Link Preview">
    Go to **Chat & Messaging --> Features**, under **Extentions** and enable **Link Preview**.
  </Step>
</Steps>

### How does it work?

We provide a few details about the URL that is in your message:

* **Description**: Summary text pulled from the page.
* **Favicon**: The site's icon for display.
* **Image**: Preview image for the link.
* **Title**: Page title resolved from the URL.
* **URL**: The final resolved link.

<Warning>
  Links that take more than a second to resolve will be automatically skipped to keep in-flight transit time to a minimum.
</Warning>

## Message shortcuts

The Message shortcuts extension enables your users to send predefined messages. For example, **!hb** can be automatically expanded to **Happy birthday!**

**When to use:** Support teams with canned responses, communities with common greetings, or any app where users send repetitive messages.

  **Out-of-the-box in:** [UI Kit Builder](/chat-builder/react/features) <Tooltip tip="Not available out of the box in the UI Kit — supported via the SDK and requires custom implementation.">🔨</Tooltip> | [Widget Builder](/widget/html/features) ❌ | [UI Kits](/ui-kit/react/core-features) <Tooltip tip="Not available out of the box in the UI Kit — supported via the SDK and requires custom implementation.">🔨</Tooltip> | [SDK](/sdk/javascript/overview) ✅

<Note>
  Global shortcuts are available to all users. User-created shortcuts are private to the creator.

## Rich Media Preview

The Rich Media Preview Extension generates rich preview panels for all popular sites using Iframely. Returns ready-to-render HTML embeds for YouTube videos, tweets, and more.

**When to use:** You want polished, interactive embeds without building custom preview components.

## Save Message

Let users save important messages and revisit them later. Works like bookmarking - users can build a personal collection of important messages.

**When to use:** Apps where users need to reference information later, like saving addresses, instructions, or important announcements.

## Thumbnail Generation

The Thumbnail Generation extension generates thumbnail previews for image and video messages. Improves load times by showing small previews before users download full media.

**When to use:** Any app with media sharing - especially important for mobile users on slower connections.

<Note>
  **Out-of-the-box in:** [UI Kit Builder](/chat-builder/react/features) ✅ | [Widget Builder](/widget/html/features) ✅ | [UI Kits](/ui-kit/react/extensions#thumbnail-generation) ✅ | [SDK](/sdk/javascript/overview) ✅
</Note>

### Extension settings

<Steps>
  <Step title="Open your CometChat app">
    Login to [CometChat](https://app.cometchat.com/login) and select your app.
  </Step>

  <Step title="Enable Thumbnail Generation">
    Go to **Chat & Messaging --> Features**, under **Extentions** and enable **Thumbnail Generation**.
  </Step>
</Steps>

<Note>
  Unlike image thumbnails, which are normally generated in milliseconds, video thumbnails may take a little longer.
