How to Use the Duplicate Line Remover:

1 Paste or type your text into the "Enter your text" area, with each item on a new line.
2 Check the "Case-sensitive" box if you want to treat lines with different casing as distinct (e.g., "Apple" and "apple" would both be kept if unchecked, but only the first occurrence if checked and both exist).
3 Click the "Remove Duplicates" button.
4 The text with duplicate lines removed will appear in the "Text without Duplicates" area.
5 Click "Copy Output" to copy the result to your clipboard.
