Text Difference Checker
Compare two texts side-by-side and highlight differences instantly.
What diffs are for beyond Git
You diff two texts to see what changed between versions of a config, a contract paragraph, a translation, or a long email draft. A visual diff highlights insertions and deletions so you can review faster than with eyeball scanning. It is a communication tool as much as a development tool.

How to read results constructively
Ignore whitespace-only changes if your tool allows, because they hide meaningful edits. If the text moved blocks around, a diff can look noisier than the conceptual change. For legal text, a single comma can matter, so do not over-trust a green/red summary without reading the sentence in context.
Sensitive content
Do not diff secrets on untrusted devices. The comparison should stay local, but the overall risk of shoulder surfing still exists in public places.
