1. How to Use
- Enter the first text in the left input field and the second text in the right input field.
- Click Compare Texts to analyze and highlight differences. Additions appear in green, removals in red.
- Use Copy buttons to copy either text to your clipboard. Click Reset to clear all inputs.
2. How It Works
The tool uses a diff algorithm that splits text by sentences (using ., !, ?, and newlines) and then compares word by word.
Additions (text in the second input but not the first) are highlighted in green. Removals (text in the first but not the second) are highlighted in red.
