 > **Bring Your Own API Key**: You can use your own API key to bypass usage limits on the demo site. Click the Settings icon in the chat panel to configure your provider and API key. Your key is stored locally in your browser and is never stored on the server.
 
+### Desktop Application
+
+Download the native desktop app for your platform from the [Releases page](https://github.com/DayuanJiang/next-ai-draw-io/releases):
+
+| Platform | Download |
+|----------|----------|
+| macOS | `.dmg` (Intel & Apple Silicon) |
+| Windows | `.exe` installer (x64 & ARM64) |
+| Linux | `.AppImage` or `.deb` (x64 & ARM64) |
+
+**Features:**
+- **Secure API key storage**: Credentials encrypted using OS keychain
+- **Configuration presets**: Save and switch between AI providers via menu
+- **Native file dialogs**: Open/save `.drawio` files directly
+- **Offline capable**: Works without internet after first launch
+
+**Quick Setup:**
+1. Download and install for your platform
+2. Open the app → **Menu → Configuration → Manage Presets**
+3. Add your AI provider credentials
+4. Start creating diagrams!
+
 ### Run with Docker (Recommended)
 
 If you just want to run it locally, the best way is to use Docker.
