I am excited about the potential of the AI search, in my use of it so far in the beta I find it is much more intuitive and has been a big quality of life improvement for people like me who are trying to get to a lot of material in a short period of time.
A suggestion I have is that it seems to do best when given a narrower collection; such as "What does Luther say about the daily rememberance of baptism?" when applied only to my collection of Luther's Works. This has led to big improvements in getting rid of fluff.
I think that it would be helpful if the AI was also used to make smarter collections on its own; which currently are a kind of pain to use. I want to be able to say, "What do the Lutheran confessional orthodox fathers say about..." and get all of the Chemnitz, Gerhard, Quenstedt etc that I have in my library, without having to wade through a pile of tepid Spurgeon and R.C. Sproul books that I regret adding to my library because they were free.[:P] I can make my own collections manually, and that is what I plan to do now, but I think the AI could do it according to sets of preferences or the specifics of the question. I often forget to go and update my collections when I have added new books to my library.
When I ask an archaeology question, I want it to prioritize my archaeological books, etc. ChatGPT has proven to be capable of understanding what these sorts of collections would consist of, and I think applying that kind of filtering and sorting would be very useful.
Furthermore, getting the AI summarization to work to summarize the COMPLETE results of a search in one paragraph with footnotes would be a further coup. Especially if said footnotes are actually ref-links back to the material in my library.
I also would love to see the AI summarization happen to sets of result collections on things like the factbook. I have a very large library and get 20 dictionary results for some factbook entries. I would like to see it summarize and pull out salient details and disagreements between the different results. I know that the AI can do it, so I would love to see it implemented in a future version.
