DunMac

Control your Mac from your phone using AI. That's it.

I built this for a demo at the UnitedBy.AI gathering in Chennai. Wanted to show how you can talk to your Mac like a human and have it actually do stuff.

What it does

You type (or say) things like:

• "Open Safari and go to google.com"
• "Play some jazz on Spotify"
• "Take a screenshot"
• "Set volume to 50%"
• "Toggle dark mode"

And your Mac does it. From your phone. From anywhere.

How it works

┌────────────────┐      HTTPS       ┌───────────────────────────────────┐
│   Phone/Web    │  ──────────────→ │   Hono Server (runs on Mac)       │
│   (anywhere)   │      tunnel      │   - AI (Claude via OpenRouter)    │
│                │  ←────────────── │   - Tool execution (osascript)    │
└────────────────┘                  └───────────────────────────────────┘

The AI (Claude via OpenRouter) takes your natural language and picks the right tools to run. Music control, screenshots, opening apps, system settings - all through AppleScript and shell commands.

Tools

Tool	What it does
open_app	Open any macOS app
open_url	Open URL in browser
say	Text-to-speech
notify	Show macOS notification
screenshot	Capture screen
shell	Run safe shell commands
music_play	Play music (Apple Music/Spotify)
music_pause	Pause playback
music_next	Next track
music_previous	Previous track
volume_set	Set volume (0-100)
volume_mute	Mute/unmute
dark_mode	Toggle dark mode
lock_screen	Lock screen
battery_status	Get battery info
running_apps	List running apps
front_app	Get focused app

Setup

bun install
cp .env.example .env
# add your OPENROUTER_API_KEY from openrouter.ai/keys

Run the server:

cd apps/server && bun run dev

Create a tunnel so your phone can reach it:

cloudflared tunnel --url http://localhost:3456

Start the web app:

cd apps/web && bun run dev

Open localhost:5173 on your phone, paste the tunnel URL, connect. Done.

Tech

• Bun + Hono for the server
• Claude Sonnet via OpenRouter for the AI
• SvelteKit for the web app
• AppleScript for Mac automation
• Cloudflare Tunnel for remote access

Security

Only allowlisted commands run. Dangerous stuff like rm -rf or sudo is blocked. No auth in this version though - add that if you're using this for real.
