There's a lot of stuff in this space that hasn't been done yet, but that's for a very good reason. First of all, it doesn't pass the toothbrush test: it's the type of thing that's super valuable the first time you visit but you don't really need to come back to it over and over.

Second big problem: SEO. Search engines like long form written content, they don't know how to value tools that slice and dice data: they simply don't see any value in it and you'll never get SEO from it.
