Remove duplicate lines

Delete repeated lines from a list while keeping the original order.

Paste any list — emails, keywords, URLs — and get each unique line exactly once, with a count of what was removed.

Frequently asked questions

Is the comparison case-sensitive?

Yes — “Apple” and “apple” are treated as different lines. Use the Case Converter first to normalize if needed.

Is the original order preserved?

Yes, the first occurrence of each line stays in place; later repeats are removed.
