File Comparison

1. Upload two text files
2. Click "Compare Files"
3. View the differences highlighted in the output

Direct Text Comparison

1. Paste text into the "Original Text" area

How it Works

The application uses Python's difflib module to detect differences between texts at both the line and word level. The differences are then displayed with color coding:

• Green: Added content
• Red: Deleted content
• Yellow: Changed content
