+            ### 🎯 Premium Features for Accessibility
+            
+            **For Visually Impaired Users:**
+            - **Automatic Text Detection**: Our system automatically detects existing text in your uploaded images
+            - **Comprehensive Descriptions**: Get detailed accessibility information including detected text and added overlays
+            - **Screen Reader Friendly**: All outputs are optimized for screen reader compatibility
+            
+            **How It Works:**
+            1. **Upload** your image using the file picker or drag-and-drop
+            2. **Enable** "Detect existing text in image" to automatically find text already present
+            3. **Add** your new text with customizable position, size, and colors
+            4. **Review** the accessibility information that combines detected text and your additions
+            5. **Download** the final image with complete accessibility metadata
+            
+            **Accessibility Best Practices:**
+            - Always provide meaningful custom descriptions when possible
+            - Use high contrast colors for better visibility
+            - Consider the context of existing text when adding new overlays
+            - The accessibility information is designed to be read by screen readers
