Common questions

Are the two texts uploaded?
No. Both texts are compared in your browser; nothing is sent to a server.
How detailed is the comparison?
Changes are aligned side by side or as a unified diff, with word-level highlighting inside changed lines, collapsible unchanged runs, and next/previous change navigation.
Can I ignore noise like whitespace or case?
Yes. You can ignore blank lines, edge whitespace, trailing newlines and case, and you can load either side straight from a file.
