Thank you @bumpy-butcher-41910 for the quick reply. I'm sorta tearing my hair out trying to figure out if I can build a bot to do what I want to do, which is to act as a co-pilot and companion for a curriculum guide, helping teachers to explore the guide, find content they want to work with, and then develop that into lesson plans and such. The sort of thing AI is really great at. But if the guide gets vectorized, this is not so easy to do, apparently. It seems that rather than the guide itself being a knowledge base document, I'll need to actually bring the content right into the workflow. Hmmm, design rethink.
