Questions and answers

Does it compare word by word?

No. It compares line by line, so a small change inside a line shows as one line removed and one line added.

Do spaces count as changes?

Yes. A difference in spaces or capital letters makes two lines different.

Is there a size limit?

Each side can have up to 2000 lines.

Is my text uploaded?

No. The comparison runs in your browser.
