I made an encyclopedia where every page is generated by LLM on demand, so there's no such thing as a topic that doesn't have a page. It's like a real life hitchhiker's guide to the galaxy.
I like the idea but it's "hallucinating" a lot. An example that I often use is to search for a building not too well know in a small city. If the information (such as architect, building date) is online, but the content generated is wrong, it fails my test.
