✨ Why Extra?

Today's AI assistants can write brilliant essays and code, but they are trapped inside a chat window. When you need them to click a button, open an app, organize your files, or input data into a spreadsheet, they can only give you text instructions.

Extra gives your AI hands and eyes on Linux, macOS & Windows.

It connects Claude, Google Antigravity, Cursor, AGY, or any autonomous agent directly to your desktop with high-speed screen vision, pixel-perfect clicking, and instant typing.

No clunky browser extensions.
No expensive cloud servers watching your screen.
100% open source, local, and private.

💡 What You Can Ask Your AI To Do

Once Extra is running, you can talk to your AI like a real human assistant sitting at your desk:

📊 Spreadsheets & Data: "Open Excel or LibreOffice Calc, calculate total revenue from the invoice CSVs in my Downloads folder, and create a summary chart."
🗂️ Desktop & File Cleanup: "Clean up my messy desktop by moving screenshots into Pictures, PDFs into Documents, and deleting empty folders."
🌐 Web Research & Data Entry: "Open Chrome or Firefox, find the top 5 flights to Tokyo under $800, and copy their flight numbers and dates into a text note."
⚙️ System Administration: "Open Settings or terminal, check system updates, and verify service health."
🎵 App Control: "Launch Spotify or VLC, search for low-fi focus beats, and start playing."

⚡ Quickstart (1 Minute)

You can set up Extra in seconds on Linux, macOS, or Windows:

Option A: Ask Your AI To Set It Up (Primary Funnel — Easiest)

Copy and paste the single directive for your OS into Claude Desktop, Google Antigravity, Cursor, Windsurf, or any MCP agent:

🐧 For Linux (Arch / yantraOS, Ubuntu, Debian, Fedora):

Setup Extra on my Linux machine: In Terminal run 'curl -sSL https://extra.yantraos.com/install.sh | bash', then read and configure ~/.extra/app/STARTER_PROMPT_LINUX.md so we are ready to use Extra.

🍏 For macOS (Apple Silicon M1-M4 & Intel):

Setup Extra on my Mac: In Terminal run 'curl -sSL https://extra.yantraos.com/install.sh | bash', then read and configure ~/.extra/app/STARTER_PROMPT_MACOS.md so we are ready to use Extra.

🪟 For Windows (11 / 10):

Setup Extra on my PC: In PowerShell run 'iwr -useb https://extra.yantraos.com/install.ps1 -OutFile "$env:TEMP\install_extra.ps1"; & "$env:TEMP\install_extra.ps1"', then read and configure ~/.extra/app/STARTER_PROMPT.md so we are ready to use Extra.

Your AI will run the installer, configure MCP and local rules, and reply:

"We are ready! Please restart <your AI application, e.g. Claude Desktop, Antigravity, Cursor, Windsurf> to make it work."

Option B: Run the One-Liner Yourself

🐧 Linux Terminal (Arch / yantraOS, Ubuntu, Debian, Fedora):
```
curl -sSL https://extra.yantraos.com/install.sh | bash
```

🍏 macOS Terminal:

curl -sSL https://extra.yantraos.com/install.sh | bash

🪟 Windows PowerShell (Staged, Defender-Clean):

iwr -useb https://extra.yantraos.com/install.ps1 -OutFile "$env:TEMP\install_extra.ps1"; & "$env:TEMP\install_extra.ps1"

The automated installer will:

Verify OS architecture (Linux Wayland/X11, macOS 12.3+, or Windows 10/11 64-bit).
Provision isolated Python 3.10+ runtime (~/.extra/venv).
Auto-configure Claude Desktop, Cursor, Windsurf, and Antigravity (agy).
Run the health diagnostic doctor and present the 1-step starter prompt.

Option C: Developer Git Clone

# Linux / macOS:
git clone https://github.com/AIYantra/extra.git ~/.extra/app
cd ~/.extra/app && ./install.sh

# Windows:
git clone https://github.com/AIYantra/extra.git "$HOME\.extra\app"
cd "$HOME\.extra\app" ; .\install.ps1

Connecting to Any MCP-Compatible AI

Extra works out of the box with any agent supporting the Model Context Protocol (MCP). If you use Cursor, Windsurf, or custom agents, add this snippet to your MCP config:

{
  "mcpServers": {
    "extra": {
      "command": "npx",
      "args": ["-y", "@yantraos/extra-desktop"]
    }
  }
}

Or using native Python:

{
  "mcpServers": {
    "extra": {
      "command": "python",
      "args": ["-m", "extra.mcp.server"]
    }
  }
}

🎯 How It Works Under The Hood

Extra is engineered from the ground up for speed, reliability, and token efficiency:

👁️ Ultra-Fast Screen Capture (< 3ms): Uses native DirectX Desktop Duplication (DXGI) to take crystal-clear desktop frames in under 3 milliseconds—without lagging your PC or blurring text.
🎯 Pixel-Perfect Clicking: Rather than guessing coordinates from fuzzy screenshots, Extra queries the native Windows accessibility tree (UI Automation) to click the exact button, menu, or text field with 100% mathematical accuracy.
⚡ Instant Typing: Types 500 characters in under 5 milliseconds via native Win32 Unicode injection—with zero dropped letters and full support for emojis and international languages.
🛑 Infinite Loop Stall Protection: If an app freezes or a click produces no visual result, Extra immediately catches it and stops safely instead of burning your tokens in an endless loop.
🔒 100% Local & Private: Extra runs completely on your machine. Zero screenshots, keystrokes, or telemetry are ever sent to any cloud server.

📊 Performance Comparison

Metric / Capability	Legacy Scripts (`PyAutoGUI`)	Cloud Vision Models	Extra Engine
Screen Grab Speed	150 – 300 ms	80 – 150 ms	1.8 – 3.2 ms (DirectX DXGI)
Typing Speed (100 chars)	2.5 – 5.0 seconds	1.0 – 2.0 seconds	< 0.005 seconds (Instant Win32)
Click Accuracy	~60% (fails on display scaling)	~82% (vision guess)	99.4% (Native Windows UIA)
Multi-Monitor DPI Support	Broken on 125%/150% scales	Requires manual adjustment	Automatic (PerMonitorV2)
AI Token Cost	High (full screenshot every step)	High (full vision payload)	70% Lower (Smart element tree)
Stall Prevention	None (gets stuck forever)	Basic timeout	Smart visual delta detection
