I've been using Gemini for a year or two and find the ability to create my own criteria for queries very helpful. Example: I asked the Study Assistant to explain what Peter says about God in 1 Peter 1:1-3. The response used references from Dr. Doriani, whom I would not use if I could add criteria for sources that conform to Reformed Baptist Theology rather than Reformed Presbyterian Theology. This might be more involved than my earlier suggestion concerning the book collections. But if you gave me the ability to select my collections, it would give me some control. Think about adding user-defined criteria to your AI engine. Thank you.
