+                ### 🚀 The Vision
+                
+                **Stop leaving money on the table.** Most people use the same 1-2 credit cards for 
+                everything, missing out on hundreds of dollars in rewards annually. But manually 
+                calculating the optimal card for every purchase is impractical.
+                
+                **That's where AI comes in.**

+                ### 💡 The Problem We Solve
+                
+                #### Real-World Scenario:
+                
+                You're standing at a checkout counter with **5 credit cards** in your wallet.
+                
+                **The Question:** Which card should you use for this $85 grocery purchase?
+                
+                #### Manual Calculation (What Most People Do):
+                
+                1. Remember reward rates for all 5 cards ❌ (takes 30+ seconds)
+                2. Check if you've hit spending caps this month ❌ (requires tracking)
+                3. Calculate actual rewards for each card ❌ (mental math)
