About Text compare

Paste an original and a changed version of any text into the two boxes and they're compared line by line in your browser. The side-by-side view aligns matching lines and highlights the rest: lines only on the left are removed, lines only on the right are added, and modified lines show the exact words that differ. A summary counts the added, removed and changed lines, and you can ignore case or whitespace to focus on meaningful differences. Nothing is uploaded — the comparison runs entirely on your device. This tool is page-only and isn't available as a dashboard widget.
