Text-Difference Checker

Compare two texts line by line and highlight added and removed lines.

Compare two texts line by line and highlight added and removed lines.

How to use

The two texts are split into lines and aligned with a longest-common-subsequence algorithm. Lines present only in the original are marked removed, lines present only in the changed text are marked added, and matching lines are shown unchanged.

Example

Comparing "line one line two" with "line one line 2" marks "line two" as removed and "line 2" as added.
