Have you tried Google's Notebook LM, yet? You should check it out if you haven't. It is basically your own personal language model, it can search and reference any document you upload to it. So, you upload a bunch of documents (or multimedia files, or URLs), and then you can have your notebook create an outline of the content, a study guide, a FAQ document, etc. You can query the notebook and it doesn't just use all of the info on the internet to arrive at an answer, it specifically searches what you have uploaded, and its answer contains citations with links to specific areas within those sources. Very helpful for anything that requires sifting through tons and tons of material. It is free for now, but I am sure they will charge eventually.
It can also create a podcast from your content, where 2 robots talk back and forth about the content in a way that is completely indistinguishable from 2 humans having a normal conversation. It will blow your mind.
On a related note, I teach physiology at U of Iowa, and I am quite confident that ChatGPT (or Copilot, which I primarily use because UI has a license) would ace all of my exams. I have not yet been able to give it a multiple-choice question that has stumped it. I encourage my students to use it for practice-questions and as a free tutor. On the flip side, so far it sucks at Biomechanics (another topic I teach).
If you have kids and a multi-modal chatbot (e.g. Pilot can be queried with audio input), you can have your kids ask the bot a question, or what my kids love, is have them ask the bot to make up a story for them. It can even make cover art (sort of)! My kids get a kick out of it.
