Frequently Asked Questions

What does the text diff tool do?

It compares two pieces of text word-by-word using a longest common subsequence algorithm (similar to git diff) and highlights words that were added, removed, or unchanged.

Is my text kept private?

Yes. All comparison happens in your browser — no text is ever sent to a server.
