Frequently Asked Questions

>Is my text sent to a server??

No. The diff is computed entirely in your browser using a line-based LCS algorithm. Your text never leaves your device.

>What does ignore whitespace do??

It normalizes whitespace when comparing lines, so changes in indentation or trailing spaces are not reported as differences.
