Remove duplicate lines from any list
Paste email lists, phone numbers, keywords, product codes or names — one per line — and get a clean list with each entry only once, in the original order (or sorted). Options ignore capital letters and extra spaces so Rahul@Example.com and rahul@example.com count as the same. The count of removed duplicates is shown.
Switch to duplicate words mode to remove repeated words inside a sentence or keyword string (useful for meta keywords and tag lists). Compare two lists with text compare, or count entries with the word counter.
