Text Difference Checker
Compare two versions of text and see exactly which lines changed.
Compares line by line — reordered lines will show as removed and added rather than moved.

How It Works
Paste the original text on the left and the changed text on the right. Differences are highlighted line by line.
Example
Frequently Asked Questions
- Does this detect moved lines?
- No — this compares line by line in order, so a line that moved to a different position shows as one removed and one added, not as "moved".
- Can I compare code with this?
- Yes, though for code specifically a dedicated code diff tool may highlight syntax better — this works fine for general text and simple code comparisons.
