Frequently asked questions
How does the comparison work?
Paste two blocks of text side by side and the tool highlights exactly what was added, removed, or changed between them.
What is it good for?
It is perfect for reviewing edits, comparing document versions, checking configuration changes, or catching subtle differences you might otherwise miss.
Is there a length limit?
You can compare anything from a couple of lines to large blocks of text — it all happens instantly in your browser.
Is my text uploaded?
No — the comparison runs entirely in your browser, so both blocks of text stay private on your device.
