What Is a Text Compare Tool?
A text compare (or diff) tool lets you place two pieces of text next to each other and highlights every addition, deletion, or change. It is indispensable for developers reviewing code changes, writers tracking document revisions, and students comparing essay drafts.
How It Works
- Paste the original text in the left panel.
- Paste the modified text in the right panel.
- Differences are highlighted automatically — additions in green, deletions in red.
Key Features
- Split-screen layout for easy visual comparison.
- Line-by-line diff highlighting.
- Works entirely in your browser — no data leaves your device.
- Responsive design that works on mobile and desktop.
