Text Difference Checker
Compare two blocks of text side-by-side and instantly see which lines were added, removed, or changed — color-coded for easy review.
What Does This Tool Do?
When you have two versions of a text — maybe a document before and after editing, or two different config files — this tool shows you exactly what changed. Added lines are highlighted in green, removed lines in red, and changed lines in yellow. You can see at a glance what's different without reading every word.
Key Features
How to Use This Tool
- Paste the original text into the "Text A" panel.
- Paste the changed text into the "Text B" panel.
- Click Compare to see the highlighted differences.
How It Works
The tool compares both texts line by line. Lines that exist only in Text B are marked as added (green), lines only in Text A are marked as removed (red), and lines present in both but with different content are marked as changed (yellow).
Common Use Cases
Frequently Asked Questions
Is this the same as a code diff tool?
It performs the same function — line-by-line comparison — but is designed for plain text rather than syntax-highlighted code. For code, a dedicated IDE or git diff tool may be more appropriate.
Does it compare within lines or just whole lines?
The tool compares whole lines. Lines that differ in any way (even one character) are marked as changed.
