How to use Diff Checker

What is a Diff?

A diff compares two texts line by line to show what changed. It is widely used for code reviews, document revisions, and config file comparisons. Added lines appear in green, removed lines in red.

Use Cases

Review code changes, compare document revisions, check config file differences, cross-reference translations — any text comparison task.
