A little guidance

A cleaner list, in the same order

Paste a list with one item per line. The tool keeps the first occurrence of each exact line and removes later copies. It preserves the original order rather than sorting the result.

Matching is case-sensitive and includes spaces. Apple, apple, and Apple followed by a space are different entries. Clean spacing first if whitespace should not distinguish items. Repeated blank lines are also collapsed to one.

  1. Paste your text into the editor, or try the sample.
  2. Choose your settings, then use the primary action button.
  3. Copy or download the result. Use Undo to restore the last change.
Good to know

Simple by design.

Is my text stored anywhere?

No. The tools process text in this browser tab. There is no text upload, browser storage, or account history. Refreshing or leaving the page clears the editor.

Does this work on my phone?

Yes. Use a current browser on a phone, tablet, or computer. Copy may require browser permission; downloading is an alternative.
