Text diff
See what changed between two versions, by words or by lines.

How it works
Paste the original on the left and the new version on the right. Additions are green, removals red. Compare by words (finer) or by lines (better for lists and code).
It uses the longest common subsequence, the classic diff method. For very large texts it warns you and asks for a line comparison.
