When is a text comparison useful?

Contract drafts, theses, translations or config files: when comparing two versions by hand, it's easy to miss a change. This tool reliably finds every difference.

Line-by-line comparison suits code and lists, word-by-word comparison suits prose where only individual words were changed.

Frequently asked questions

Are my texts uploaded?

No. The comparison runs entirely in your browser – confidential documents stay on your device.

How long can the texts be?

Several thousand lines are no problem. For very large texts with many changes the tool shows a notice.

Can I compare Word or PDF files?

Copy the text from the documents and paste it into the two boxes.
