What is Ghost?

Ghost is a terminal agent — like Claude Code but for browser tasks. You type what you want, Ghost opens Chrome and does it on your real system with your real cookies, logins, and sessions.

No sandboxed browser. No Playwright. No Selenium. Your actual Chrome.

---

Why Ghost?

Every other browser agent sends screenshots to a vision model for every action. Ghost reads the DOM as text — 50x cheaper, faster, more accurate.

---

How It Works

Them:   Screenshot → Vision LLM ($$$) → guess pixel coordinates → click

Ghost:  Read DOM as text → LLM picks element ID → exact click
        + OCR catches popups, dialogs, overlays
        + Memory replays known tasks at zero cost

Three perception layers, cheapest first

Permissions

When Ghost starts, it asks for permission to:

Permission	Why Ghost needs it
Browser Control	Navigate, click, type in Chrome via DevTools Protocol
Screen Reading	OCR for popups, dialogs, and overlays outside the DOM
File System	Read/write files, handle downloads
Clipboard	Copy/paste data between apps
App Management	Open/close/fullscreen Chrome
Keyboard/Mouse	Physical input when DOM clicks aren't enough

Ghost runs on your machine. Nothing is sent to any server except LLM API calls (your chosen provider).

Fresh Mac Setup (step by step)

  First-time Setup

  Ghost needs an API key to talk to AI models.
  Get a free key at https://openrouter.ai

  Enter your OpenRouter API key: sk-or-v1-xxxxx
  ✓ API key saved. You won't need to enter this again.

  Permissions
    ◉ Browser Control
    ◉ Screen Reading
    ◉ File System
    ◉ Clipboard
    ◉ App Management
    ◉ Keyboard/Mouse

  Grant all permissions? [y/n]: y
  ✓ Ghost is ready.

6. macOS permissions (one-time)

Ghost needs Accessibility permission to control mouse/keyboard:

1. Go to System Settings → Privacy & Security → Accessibility
2. Add your terminal app (Terminal, iTerm2, or VS Code)
3. Toggle it ON

That's it. Ghost auto-syncs your Chrome profile (cookies, logins, everything).

Ghost saves settings to ~/.ghost/config.json. Edit anytime:

ghost> /config
  API Key     sk-or-v1...fc283

  Provider    openrouter
  Config      ~/.ghost/config.json

ghost> /config key sk-or-v1-your-new-key
