Line-by-line diff
How this comparison works
The tool uses a line-level longest common subsequence to mark added, removed, and unchanged lines. When whitespace or case is ignored for matching, the displayed text still preserves the original input.
This is useful for copy, small configuration snippets, and drafts. The exported text is not an apply-ready Git patch, and it does not detect semantic or word-level changes. Use version control for large codebases.
