Diff Checker

Compare two blocks of text or code and highlight differences

What is this tool?

Compares two blocks of text or code and highlights exactly what's different between them, line by line.

How to use it

Paste your two versions of the text into the two panels, and the differences are highlighted automatically.

This is useful well beyond code — comparing two drafts of a document, or two versions of a contract, works the same way and is often faster than manually reading both side by side.
