Clean up any list in seconds
Merged contact lists, exported keywords and copied URLs are full of repeats. Paste the list here and every duplicate line is removed instantly, keeping the first occurrence and the original order.
Choose whether “Apple” and “apple” count as the same, whether trailing spaces matter, and whether to drop empty lines or sort the result. The counters show how many lines came in, how many repeats were removed and how many remain.

Tips and good to know
- Lines must match completely to count as duplicates. To remove repeated words inside a sentence, a different approach is needed.
- Sorting after de-duplicating makes lists easier to scan — try the Text Sorter for more sort orders.
