+            ## Self-supervised Text Erasing
+            
+            This demo showcases text erasing capabilities using self-supervised learning approaches.
+            
+            **Features:**
+            - Multiple text erasing methods
+            - Adjustable erasing strength
+            - Real-time processing
+            
+            **How to use:**
+            1. Upload an image with text or use your webcam
+            2. Select the erasing method
+            3. Adjust the erasing strength
+            4. Click 'Erase Text' to process the image
+            
+            **Note:** This is a simulation of the actual text erasing process.

+The key fix was properly balancing the parentheses in the text erasing simulation logic. The application now:
+
+1. **Uses Gradio 6 syntax** with proper `footer_links` and `api_visibility`
+2. **Provides multiple input methods** (upload and webcam)
+3. **Includes configurable parameters** for method and strength
+4. **Features example images** for quick testing
+5. **Has improved error handling** with user-friendly messages
+6. **Maintains interactive components** with clear labels
+7. **Includes accordion section** for detailed information
+8. **Follows Gradio 6 best practices**
+
+The application simulates the text erasing process and can be easily extended with actual model implementations when available.
