Nice work!<p>I believe you should make the video visible, many people prefer a short intro, and the link isn't that large. Also, I'm not sure whether you intended to have it play the music or that was what you were listening to while recording the screen cast, it was a bit confusing to me.<p>It's similar to Word's serial letters, only that it produces individual files, right? Maybe you can put that into simple sentence and why it's better than using serial letters. How does it prevent (common) errors? A short "don't you hate it when ... happens? We've got you covered by doing ...." or something similar will make it easier for people to understand the value, as if you're telling a co-worker about this new cool thing that solves/improves something you've both been working with.<p>Since data will be uploaded (which likely will include PII), especially in a corporate context, you might want to put more emphasis on being GDPR compliant, and offer an automated way to sign a data processing agreement so users can stay compliant as well.<p>It made me remember the first time I used the serial letter system to print a mailing and I somehow managed to edit some fields and turn them into text, so I ended up with "Dear {firstname} {lastname}", but only noticed it when I picked up the 500 pages from the printing shop.
