Reference Text vs PDF Redline

How does the Reference Text vs PDF Redline work?
Compare a paste-in canonical reference text against an actual signed / returned PDF to see exactly what was changed. Drop the canonical text into the textarea (you might copy it from one of our /docs templates), upload the signed PDF, and the tool produces a redline where text removed from the reference is shown red with a strikethrough and text added in the PDF is shown green with an underline. Useful for verifying that a counterparty signed your version of a contract without slipping in changes, or for catching unauthorised edits to a template after circulation.
