Paste lists, logs, or exports to collapse repeated rows. The first copy of each line stays; later duplicates disappear—handy before sorting or diffing.

How it works
Lines are split on newline characters; exact string equality decides duplicates.
Leading and trailing spaces matter: two lines with different spaces are not duplicates.
Trimming
Trim first in a text editor if you need to ignore surrounding spaces.
