# Grok Build

> Use Exa web search in Grok Build. Install the Exa plugin from the Grok Build marketplace and sign in with your Exa account.

Exa is available as a plugin on the [Grok Build](https://docs.x.ai/build/overview) marketplace. It gives Grok real-time web search, page reading, and a deep research skill.

## Installation

<Steps>
  <Step title="Install Grok Build">
    Install the Grok CLI (see the [Grok Build docs](https://docs.x.ai/build/overview) for details):

    ```bash theme={null}
    curl -fsSL https://x.ai/cli/install.sh | bash
    ```

    Then sign in to your xAI account:

    ```bash theme={null}
    grok login
    ```
  </Step>

  <Step title="Open the marketplace">
    Start Grok Build by running `grok`, then open the marketplace:

    ```text theme={null}
    /marketplace
    ```
  </Step>

  <Step title="Install the Exa plugin">
    Find **exa** in the list and press `i` to install it.
  </Step>

  <Step title="Sign in to Exa">
    Open the MCP servers tab with `/mcp`, select **exa**, and press `i` to sign in. Your browser opens the Exa sign-in page. New accounts get free credits at signup.
  </Step>
</Steps>

Once exa shows **ready**, ask Grok anything that needs the web.
