Frequently Asked Questions

Does my list leave the browser?

No. Deduplication, trimming, empty-line removal, and sorting all run locally in your browser. The text is not uploaded.

How are duplicates detected?

By default, exact line text is used. You can trim lines before comparison and ignore case for duplicate detection while preserving the first kept line's original casing.

Can I keep the original order?

Yes. Leave sorting set to none to preserve the first occurrence order after filtering. Choose ascending or descending only when you want a sorted output.
