Duplicate Line Remover
Remove repeated lines from text in the browser while preserving order, with case and whitespace options.
This tool handles input and primary processing in your browser and is designed not to send the input to QuickKit’s server.
How it works
Keep-first and keep-last remove extra copies but keep one of each line. Unique-only keeps just the lines that never repeat. Order is otherwise preserved.
