Compare two versions (redline)
Paste the old and the new text, or pick two versions of a document you saved on SealForms. Every changed word is highlighted:added and removed. Nothing is uploaded — the comparison runs in your browser.

Word-by-word comparison generated in the browser with SealForms. Review the full documents before relying on any change.
How the comparison works
The tool splits both texts into words and finds the longest sequence they share. Anything only in the new text is shown as added; anything only in the old text as removed. Moved paragraphs appear as a removal plus an addition.
To compare versions of a document you built here, open My documents: every “Save” or “Update” keeps the previous version (up to 20 per document), and each one has a “Compare with current” button.
Everything stays on your device — the texts you paste are not stored or sent anywhere.
