Iirc there was a link posted at the end of the talk?

Edit: I just realized I was thinking of the patchwork demo.

Either way, after using a Remarkable for years, I've wanted something that actually tried to make use of the "digital" part of digital paper. When I came across you guys a few years ago, I was hooked (tbh, would love to work for you guys). So seeing the playbook demo was very exciting.
