How to use it
Use the comparison to review revisions in notes, lists, configuration, or other line-oriented text.
- Paste the original text on the left and the changed text on the right.
- Choose whether case or repeated surrounding whitespace should be ignored for comparison.
- Compare the texts and review the unified result with old and new line numbers.
Worked example
- Input
Original: alpha\nbeta
Changed: alpha\nbravo
- Output
1 1 alpha
2 − beta
− 2 bravo
Comparison options change only matching keys; displayed lines keep their original spelling.
Method and definitions
- A line-level Myers shortest-edit-script algorithm finds insertions and deletions.
- A changed line appears as one removal followed by one addition, so the transformation stays explicit.
Limits and edge cases
- The result is line based; it does not highlight individual characters inside a line.
- Each side is limited to 5,000 lines and the combined UTF-8 input to 1 MiB.
