Questions

Is my text sent anywhere?

No. Duplicates are removed in your browser, so your text stays on your device.

Does it keep the original order?

Yes, unless you choose a sort option. The first copy of each line stays where it was.

Can it ignore upper and lower case?

Yes. Turn on Ignore case to treat 'Apple' and 'apple' as the same line.

Can I also sort the lines?

Yes. Choose A to Z or Z to A to sort the remaining lines.
