Frequently asked questions
How does the comparison work?
The tool computes a longest-common-subsequence diff line by line (the same approach used by git), so unchanged lines stay aligned and only real changes are highlighted.
Is my text uploaded to compare?
No, the diff is computed entirely in your browser, so your text is not uploaded anywhere. Drafts are saved in this browser's localStorage as you type, so avoid sensitive text on shared devices.
Is there a size limit?
Automatic comparison runs up to 20,000 combined characters; for larger text, select Compare to update the differences. Each side is also capped at 3,000 lines. Beyond that, the tool shows an error instead of a truncated result.
