How is this made?

An AI model reads the channel’s public details: its name, description, keywords and stats, and the titles, dates, lengths and tags of its 30 latest videos. It doesn’t watch the videos, so it can miss things. It’s refreshed about every two months, or sooner when the channel changes.
