  • Paste the revised text into the right box.
  • Click "Compare" to see the differences highlighted.
  • Review added, removed, and unchanged lines.

Frequently asked questions

Does this compare word-by-word or line-by-line?

Comparisons are made line by line, which makes larger structural changes easy to spot at a glance.

Can I compare very long documents?

Yes, though extremely long texts may take a moment longer to process and render.
