Paste any text with repeated lines and this tool removes every duplicate, keeping only the first occurrence.

Options to sort alphabetically and perform case-insensitive matching are available.
Clean lists, de-duped keyword sets, or unique log entries are seconds away. Paste, click Remove Duplicates, and copy the result. Combine with the Text Sorter for fully organised unique lists.
