How to use it

  1. Paste your list with one item per line.
  2. Choose options. Turn off “Case sensitive” to treat Apple and apple as the same.
  3. Copy the unique lines from the result box.

Examples

  • red, blue, red, green (one per line) → red, blue, green
  • With “Trim spaces” on, " blue" and "blue " match each other.

Lines are compared after Unicode normalization, so visually identical accented characters match. If empty lines are kept, only the first one remains.
