Looks interesting! Just a heads up as you seem to be a UK registered limited company :

This technology is useful for many industries.

At PlanGrid, we built a version of this into all of our native platforms as well as into our web app. Allowing people to see what changed between pdf revisions was a priceless tool, even for less sophisticated users in the field.

Rasterization is a must since pdfs otherwise are extremely inconsistent based on how they were generated and post-processed.

I’m going to check this out. Over the years in university, I accumulated different versions of PDFs with different annotations, because I tested various apps. It is very annoying to merge them manually.

Very nice to have a native Mac app doing this!

A related tool would be a cross-platform product the company I work for creates: i-net PDFC https://www.inetsoftware.de/products/pdf-content-comparer

PDFC compares not only graphical differences but also detects content, columns, etc. We originally created it for ourselves because we weren't happy with any of the PDF comparison tools that were out there.
