FAQ
How does the diff work?
It compares texts line by line using the Longest Common Subsequence algorithm, the same approach used by git diff.
What do the colors mean?
Green (+) = lines added in the modified text. Red (−) = lines removed from the original. White = unchanged lines.
Can I compare code?
Yes. The diff checker works with any text including source code, configuration files, essays, and more.
Is my text stored anywhere?
No. Everything runs in your browser. No data is sent to any server.
