-        ## 📘 Facebook Data Extractor
-        
-        **University Project Feature**
-        
-        **How it works:**
-        1. Enter any Facebook URL
-        2. System tries real data extraction
-        3. If blocked, uses **realistic demo data**
-        4. Choose between AI or Simple analysis
-        
-        **Analysis Modes:**
-        - 🤖 **AI Analysis**: Uses embeddings and Mistral AI
-        - 🔧 **Simple Analysis**: Rule-based (works without embeddings)
-        
-        **Perfect for demonstrating:**
-        - Social media data extraction concepts
-        - AI analysis capabilities
-        - Platform integration
-        - Error handling strategies
+        ## 📘 Facebook Real Data Extractor
+        
+        **Aggressive Approach - No Automatic Demo**
+        
+        **This version:**
+        - Tries multiple extraction methods
+        - Uses rotating user agents
+        - Attempts mobile versions
+        - Tries text-only alternatives
+        - Only uses demo data as LAST RESORT
+        
+        **Technical Challenges:**
+        - Facebook has strong anti-bot protection
+        - Requires JavaScript execution
+        - Needs session management
+        - Heavy rate limiting
+        
+        **For your project:**
+        - Shows real technical limitations
+        - Demonstrates platform security
+        - Provides educational value
