So if I understand it correctly, this app will build a model of what I like specifically, and this is some kind of neural network machine learning thing? What data does it use to figure out if I might like something (beyond tags which are mentioned clearly in the video)? Does it use what other people like to suggest content to me?
The more you like things, the more you are served the content that aligns with those likes. Right now, the easiest way for us to do that is through tags.
