About this tool
This tool compares every line in your text and removes duplicates, keeping the first occurrence of each unique line. Options let you ignore letter case, trim extra whitespace, and sort the result alphabetically.
FAQ
Does it remove empty lines? Blank lines are treated like any other line — if there are multiple blank lines, only the first is kept unless you uncheck relevant options in a future update. For now, consider trimming blank lines manually if needed.
