+# 🔍 Smart Web Monitor
+
+**AI-Powered Website Change Detection System**
+
+Monitor websites for changes automatically with AI-driven content analysis. Perfect for tracking competitor updates, news sites, or any web content you care about.
+
+## ✨ Features
+
+- 🕐 **Automated Monitoring**: Check websites every 5 minutes automatically
+- 📸 **Content Hash Detection**: Track changes via MD5 hash comparison
+- 🤖 **AI Sentiment Analysis**: Powered by DistilBERT model from HuggingFace
+- 🔍 **Manual Checks**: Instant verification anytime
+- 📊 **History Tracking**: Review all past checks
+- 🎯 **Multi-URL Support**: Monitor unlimited websites
+
+## 🤖 AI Technology
+
+This project uses **real HuggingFace Transformers**:
+- Model: `distilbert-base-uncased-finetuned-sst-2-english`
+- Task: Sentiment Analysis (POSITIVE/NEGATIVE classification)
+- Purpose: Detect tone changes in web content over time
+
+## 🚀 Quick Start
+
+1. **Add URLs**: Go to "Monitor Management" tab and add websites
+2. **Auto-Check**: System automatically checks every 5 minutes
+3. **Manual Check**: Use "Manual Check" tab for instant verification
+4. **View History**: Check "History" tab to see all results
+
+## 📋 Use Cases
+
+- 📰 News monitoring
+- 🏢 Competitor tracking  
+- 💰 Price change alerts
+- 📝 Content update detection
+- 🔔 Government notice tracking
+
+## 🛠️ Technology Stack
+
+- **Frontend**: Gradio 4.x
+- **Backend**: Python 3.11
+- **Browser Engine**: Chromium (for advanced scraping)
+- **Deployment**: HuggingFace Spaces (Docker SDK)
+
+## ⚙️ Configuration
+
+Set these environment variables in HuggingFace Spaces settings:
+
+```bash
+# Optional: Custom check interval (default: 5 minutes)
+CHECK_INTERVAL=300
+
+# Optional: Maximum URLs to monitor (default: 50)
+MAX_URLS=50
+```
+
+## 📊 How It Works
+
+1. **Hash-Based Detection**: Each check computes MD5 hash of page content
+2. **Background Worker**: Daemon thread runs checks every 5 minutes
+3. **History Persistence**: Recent 100 checks stored in memory
+4. **Smart Scheduling**: Distributed checks to avoid rate limiting
+
+## 🔒 Privacy
+
+- No data is stored permanently
+- All checks run in-memory
+- No external logging or tracking
+- Your URLs stay private
