Text Difference Checker
Someone sent back an edited contract and didn't track changes. This compares the two versions and highlights every addition and deletion — and because it runs entirely in your browser, you can paste something confidential without it leaving your device.

Questions
Is my text uploaded?
No. The comparison runs in your browser — nothing is sent to us. That's why this is safe for contracts and confidential drafts.
Word or line comparison?
Word shows precise edits inside a sentence. Line is better for code, lists and anything where whole rows move around.
What do the options do?
Ignoring capitalisation and extra spaces hides formatting noise so you only see the edits that change meaning.
