Ready · nothing is savedCompare while you edit
Paste the original text on the left and the modified text on the right. Red marks removals, green marks additions; gutter markers and labels distinguish them without relying on color alone. Both sides support selection, undo/redo and search. Tab moves focus out of the editor.
The editor compares the literal text, normalizing only line endings. A debounced JSON API call verifies the comparison; stale responses are discarded. The unified diff export uses the same texts. Each side is limited to 64 KiB and 10,000 lines for responsive editing. Nothing is stored or cached. Advanced structured/ignore modes remain available through the existing API.
