Compare modes
| Mode | Best for |
|---|---|
| Words | Most writing: shows changed words within sentences |
| Lines | Lists, code and long documents |
| Characters | Spotting typos and small edits like numbers |
The comparison uses the same approach as developer diff tools (the Myers algorithm), finding the smallest set of changes that turns the original into the new version.
