Does it preserve the order of words?

Yes. The first occurrence of each word is kept, and the order is preserved.

Is the comparison case-sensitive?

By default, comparison is case-insensitive ("The" and "the" count as duplicates). You can toggle to case-sensitive mode.

Does it remove duplicate lines too?

This tool removes duplicate words within text. To remove duplicate lines, use the Duplicate Line Remover tool.

Is my text sent to a server?

No. Everything runs in your browser. Your text never leaves your device.
