Paste a list and get it back without the repeats. Nothing you paste leaves your browser.

Does it keep the original order?
Yes, unless you choose to sort. The first copy of each line stays where it was, and later copies are dropped. Choose “keep the last copy” to keep the final version of a repeated line instead.
What counts as a duplicate?
By default, lines must match exactly. Turn on “ignore letter case” to treat Apple and apple as the same, and “ignore leading and trailing spaces” so indentation does not matter.
