The Remove Duplicate Lines tool is a simple utility for cleaning up lists, log files, or any text-based data. It processes your text and provides a new version containing only the unique lines, saving you the manual effort of finding and deleting duplicates. You can choose whether the comparison should be case-sensitive (treating "Apple" and "apple" as different) and whether to automatically remove empty lines from the output. The tool also provides a convenient summary of how many lines were in the original input and how many were removed.

1. Paste your text into the "Input Text" area on the left.
2. Choose your options:
   • Check "Case Sensitive" if you want to treat lines with different capitalization (e.g., "Apple" and "apple") as distinct.
   • Check "Remove Empty Lines" to exclude any blank lines from the output.
3. Click the "Remove Duplicate Lines" button.
4. The "Cleaned Output" area on the right will display the text with all duplicate lines removed according to your settings.
5. The cards below the options will show a count of the original lines, unique lines, and the total number of lines that were removed.
6. Click "Copy Result" to copy the cleaned text to your clipboard.
