# Install the plugin

> Install CC GUI from JetBrains Marketplace and open the tool window.

The JetBrains version of CC GUI ships as a plugin. The publisher is **MossX**, and the plugin ID is `com.github.idea-claude-code-gui`.

## Prerequisites

* A compatible JetBrains IDE (build range about 233–263.\*, for example IntelliJ IDEA 2023.3 or later)
* Access to [JetBrains Marketplace](https://plugins.jetbrains.com/)
* Git support enabled in the IDE if the project uses Git

You can install it on macOS, Windows, and Linux. Before you start chatting, you also need Node.js 18+. See [Prepare your environment](/en/jetbrains/start/setup).

## Install from Marketplace

<Steps>
  <Step title="Open plugin settings">
    Open **Settings / Preferences → Plugins** (on macOS this is often **Preferences**).
  </Step>

  <Step title="Search for CC GUI">
    On the **Marketplace** tab, search for `CC GUI` or `Claude or Codex`. The plugin display name is **CC GUI (Claude or Codex)**, published by **MossX**.
  </Step>

  <Step title="Install and restart">
    Click **Install**, then restart the IDE when prompted.
  </Step>

  <Step title="Open CC GUI">
    Click the **CCG** tool window in the right sidebar, or search for `CC GUI` actions in **Find Action**.
  </Step>
</Steps>

You can also open the Marketplace page in a browser, then click **Install**:

## Confirm the install

After install you should see:

* A **CCG** entry on the right tool-window strip
* A set of actions when you type `CC GUI` in **Find Action** (`Cmd/Ctrl+Shift+A`)
* Editor context-menu items at the top for sending a selection or copying a reference

If the tool window is empty, open a project first. CC GUI needs the project root for file references, sessions, and the working directory.

## Next step

Install only adds the UI to the IDE. To send a message, continue with [Prepare your environment](/en/jetbrains/start/setup): check Node.js, install the Claude / Codex SDKs, and install local CLIs if you need them.
