Common use cases

Compare two versions of contracts, agreements, or clauses to catch sneaky edits.
Check copy revisions, code snippets, or config file changes.
"Ignore case / whitespace" filters out noise so you only see substantive changes.

Comparison runs entirely in your browser. Nothing is uploaded to any server, so contracts and other sensitive files are safe to use here.
