Not sure how the first set of "recommended genres" are chosen - for example, "suspense" seems incredibly narrow, and similarly "speculative fiction" to include scifi/fantasy/horror is usually used rather than simply doing horror. Also why "autobiography" rather than "nonfiction"?

I also looked at your "genres" page. It's very weird that the lists don't match the bar at the top; are these things not generated from the same source? e.g. the bar starts with romance, fantasy; but the first categories are fantasy, magic. (also what is the difference between fantasy & magic)

Is there a way to add books you've already read & enjoyed to get similar recs? This is how Storygraph operates, and I've heard fantastic things about their recommendation engine, although tbh my TBR list is quite long enough and I honestly have no need for a product like this.

quick edit - also, the text of "Jurassic Park" seems to be in Spanish, while everything else is in English. Some i18n issue?
