Frequently asked questions
What does {n} do?
It becomes an increasing line number. For example, “No.{n} ” produces No.1, No.2, and so on.
Can text be added to blank lines?
Yes. Turn off “Leave blank lines unchanged”.
Is my text sent to a server?
No. Processing and storage take place only in your browser.

Check whether blank lines should change
The entered text is added before or after every line. When blank lines are included, characters are also inserted on visually empty lines. For quotes or delimiters, inspect both ends of several output lines.
