How the duplicate line remover works

Paste a list of emails, keywords, names, links or any other lines, and every line that already appeared above is removed at once. The first copy of each line stays where it was, so the order of your list doesn't change. The result updates while you type, and the counter shows how many lines there were, how many are left and how many were removed.

You decide what counts as a duplicate: turn on “Ignore case” to treat “Apple” and “apple” as the same line, and keep the option for spaces on so that a space at the start or end of a line doesn't make it different. Instead of the first copy of every line, you can keep only the lines that appear once, or only the ones that have duplicates, to see what repeats. Empty lines can be removed or left in place. Everything runs in your browser, so even long lists stay private and are processed instantly.
