## ✨ 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 Windows.**

It connects **Claude, Google Antigravity, Cursor, AGY**, or any autonomous agent directly to your Windows 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, 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, find the top 5 flights to Tokyo under $800, and copy their flight numbers and dates into Notepad."*
* ⚙️ **Windows System Tasks:** *"Open Settings, check if any Windows updates are pending, and let me know if a restart is needed."*
* 🎵 **App Control:** *"Launch Spotify, search for low-fi focus beats, and start playing."*

---

## ⚡ Quickstart (1 Minute)

You can set up Extra in two easy ways:

### Option A: Ask Your AI To Set It Up (Easiest)

Simply copy and paste this single prompt into your AI (Claude, Antigravity, Cursor, AGY):

```text
Setup Extra on my PC: In PowerShell run 'irm https://extra.yantraos.com/install.ps1 | iex', then read and configure ~/.extra/app/STARTER_PROMPT.md so we are ready to use Extra.
```

Your AI will run the installer, configure its tools, and reply:  
> **"We are ready! Please restart <your AI application, e.g. Claude Desktop, Antigravity, Cursor> to make it work."**

---

### Option B: Run PowerShell Yourself

1. Open standard **Windows PowerShell** (no admin elevation required).
2. Paste and run this one command:

```powershell
irm https://extra.yantraos.com/install.ps1 | iex
```

The automated installer will:
* Verify Windows 10/11 64-bit architecture.
* Discover or configure Python 3.10+.
* Create an isolated environment at `~/.extra`.
* Automatically connect to **Claude Desktop** (`claude_desktop_config.json`).
* Run a complete system doctor diagnostic.

### 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:

```json
{
  "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:

1. 👁️ **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.
2. 🎯 **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.
3. ⚡ **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.
4. 🛑 **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.
5. 🔒 **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** |
