Text compare: highlight the differences between two texts

Paste the old and new versions and instantly see added and removed words highlighted. Compare by word or by line; good for contracts, articles and code.

How to use

Paste the original text into the top box.
Paste the new text into the bottom box.
Read the highlights: a coloured background means added, a strikethrough means removed. Switch to line mode for long texts.

Frequently asked questions

When should I compare by line?

For source code, lists or very long texts. Compare by word when proofreading sentences.

How long can the texts be?

Several pages still run fast. Very long texts switch to line mode automatically so the browser does not freeze.

Is my text sent anywhere?

No. The tool runs entirely in your browser and sends nothing anywhere.
