Frequently asked questions
How are duplicates detected?
By default, the whole line is compared and only one copy of each repeated line is kept. It does not remove repeated words inside a sentence.
Which options can I use?
You can ignore case, trim surrounding spaces before comparison, remove empty lines, and sort the result.
Can I see the removed count and copy the result?
Yes. It shows how many lines were removed, and the cleaned text can be copied from the output area.
