Control your Windows PC from WhatsApp with AI vision

GhostPC

Control your Windows PC from WhatsApp with AI vision.

GhostPC is a local-first AI desktop agent that gives you full control of your Windows PC through WhatsApp messages. Send a text, and the AI sees your screen, moves your mouse, types on your keyboard, runs commands, launches apps, and streams your screen live to your phone.

Features

• AI Vision — Gemini Computer Use sees your screen and takes actions
• Full Desktop Control — Mouse, keyboard, scroll, drag-and-drop
• Terminal Commands — Run PowerShell/cmd from your phone
• App Launching — "Open Chrome", "Open VS Code"
• Live Screen Streaming — MJPEG stream viewable in any mobile browser
• WhatsApp Integration — Baileys-powered, QR code pairing
• Clipboard — Read/write system clipboard remotely
• File Browsing — List, search, and read files on your PC
• Emergency Stop — Ctrl+Alt+Q kills all agent activity instantly
• System Tray — Status icon showing connection state

Quick Start

Prerequisites

• Windows 10/11 (screen capture and input injection are Windows-only)
• Python 3.12+ (auto-downloaded by uv)
• Node.js 20+ (for the WhatsApp bridge)
• Gemini API key from Google AI Studio

Install & Run

git clone https://github.com/yourusername/ghost-pc.git
cd ghost-pc

# Set your API key

That's it. Scan the QR code with WhatsApp, and start texting commands.
