Frequently asked questions
Does a final line break count as a line?
No. A trailing newline at the end of the text is ignored.
How are duplicate lines counted?
The number of distinct lines that appear more than once.
Is there a size limit?
No fixed limit; it depends on your browser. Large files of several MB work fine.
