Quick guide
- Paste the baseline document on the left and the revised document on the right.
- Read unchanged context normally, removed lines with a minus marker, and added lines with a plus marker.
- Check the surrounding unchanged lines and confirm each reported change in the source document.
CHECK
Validate the result
Change one word on a single line; the tool should show the old whole line as removed and the new whole line as added.
LIMITS
Know the limits
Comparison is line based, so it does not highlight individual words inside a changed line. Large reordering can appear as removals and additions rather than moves.
Reference
Input and output example

FAQ
Frequently asked
Why is a line shown twice when I only moved it?
The longest-common-subsequence comparison does not track move operations. It represents the old position as a removal and the new position as an addition.
