Line endings are normalized for comparison. Your original texts stay intact.
Paste two versions or drop UTF-8 text files into the panels. Compare, then use the arrows to move through changes. Red is the original; green is the revision.
The focus icon folds unchanged lines. Click a folded section to reveal it. On a small screen, the two sides stack.
Use Ctrl Enter to compare and Ctrl S to save an editable HTML. PDF uses your browser’s print dialog. Exports include all lines, even folded ones.
Work stays in this tab’s session. Download an editable copy before leaving. Up to 1 MB and 10,000 lines per side. This compares text, not PDF or Word documents.
