Private by design. This tool runs entirely in your browser — nothing you enter or add is uploaded to any server.

How it works

  1. Type or paste your text into the input box — there is no practical length limit.
  2. Click one of the operation buttons (Remove duplicate lines) to transform the text instantly.
  3. The result appears in the output box; use the Copy button to copy it to your clipboard.
  4. All processing happens locally in your browser — your text is never uploaded anywhere.

Examples

  • Input "apple ⏎ banana ⏎ apple ⏎ cherry ⏎ banana" → click "Remove duplicate lines" → output "apple ⏎ banana ⏎ cherry".
  • Paste as much text as you like — long lists and whole documents work, not just short samples.
