Original text
Modified text
Compare two texts and highlight the differences line by line.
This diff checker compares two blocks of text line by line and highlights additions, deletions, and unchanged lines. It's useful for comparing code versions, checking document revisions, or finding changes between any two texts.
The tool splits both texts into lines and compares them sequentially. Lines present in the original but missing from the modified text are marked as deletions (red). Lines present in the modified text but missing from the original are marked as additions (green). Unchanged lines are shown in gray for context.
