# The Game Dev App

The AI Game Developer app is your AI pair-programmer for Unity, Unreal Engine, and Godot. Install it (desktop app or the gamedev CLI), sign in with your subscription, and pick an engine — it installs and connects the right plugin for you.

## Install

### Desktop app (recommended)

A polished agent for your desktop — voice input, chat history, and live MCP tool calls. Signed installers for Windows, macOS, and Linux, with auto-updates on launch. Download it from /download.

### gamedev CLI

The same core in your terminal — same account, same subscription, same engine support. Requires Node.js 20.19+ or 22.12+.

```bash
npm install -g @baizor/gamedev
gamedev
```

## Sign in with your subscription

Launch the app (or run gamedev) and choose Sign in. A browser window completes the OAuth device flow; your usage, history, and limits sync across the desktop app and the CLI. One subscription powers every engine. See the Authentication guide (/docs/auth) for details and for bringing your own AI client.

## Automatic engine setup

Pick an engine in the app and it does the wiring for you — no plugin wrangling.

- Installs the matching Unity, Unreal, or Godot plugin into your project.
- Connects it through ai-game.dev using your signed-in session.
- Opens the editor so you can start prompting as soon as the status pill reads Ready.
- Keeps the plugin updated as new versions ship.

Want to install a plugin yourself, or bring your own MCP client? Each engine's advanced CLI and manual setup lives on its install guide: /engines/unity, /engines/unreal, /engines/godot.
