Paste any list or text and instantly remove all repeated lines. Clean up emails, keywords, or any data in seconds.
Paste any list into the left box — email lists, keywords, names, URLs, anything. Click "Remove Duplicates" and the clean version appears on the right instantly.
Use the options to ignore upper/lowercase differences (so "Apple" and "apple" count as the same), trim extra spaces from each line, and remove blank lines from the result.
