Questions people ask
How does the comparison work?
It uses the Myers diff algorithm, the same approach as git diff, to find the fewest line insertions and deletions that turn one text into the other. Lines that changed are then compared word by word so you can see the exact edit.
Is my text uploaded?
No. The comparison runs entirely in your browser, so it is safe for private documents and code.
