ViewDesk - PDF Insights

I built ViewDesk because sending PDFs feels like throwing messages into the void. You share a pitch deck, Quotation, a brochure, or a CV… and then? Silence. Curious question for the community: if you could see exactly how someone interacts with your PDFs, which pages they read, how long they spent, where and when they opened it—how would that change the way you share documents? What would you use it for first?
