Text Diff — what changed, and nothing else

Paste two versions and see exactly what moved. Line by line, with the changed words picked out inside each line, so a reworded sentence doesn't read as a wholesale rewrite.

● Nothing is uploaded. Comparing a contract shouldn't mean sending it to a stranger's server.

What this does

Word-level inside lines. A line that had one word changed is shown as one word changed, not as a deleted line and an added line.

Collapses the boring parts. Long runs of identical text fold away so the changes aren't buried. Turn it off to read the whole thing.

Stays on your machine. No request is made. You can load this page, disconnect, and it still works — which is the point when the text is a contract or a key.
