Frequently asked questions
How does the text compare tool work?
It compares two blocks of text line by line and highlights which lines were added, removed or unchanged, so you can spot exactly what differs between two versions.
Is my text sent to the server?
No. The comparison runs entirely in your browser with JavaScript — your text never leaves your device. That makes it both private and safe.
What can I use it for?
Comparing two versions of a document, config file, code snippet or email; checking what an edit changed; or diffing anything where you need to see line-level differences.
