I've heard good things about H2O AI if you want to self host and tweak the model by uploading documents of your own (so that you get answers based on your dataset). I'm not sure how difficult it is. Maybe someone more knowledgeable will chime in.
Unknown to OP, it has now changed 11 hands over the years. Also unknown to OP, it is coming back to them as this year's Christmas present. OP is going to be very happy about it.

I don't remember how I configured it back then but now there seems to be a nice tutorial for it: https://community.jitsi.org/t/tutorial-etherpad-integration-in-jitsi-meetings/99697
It gives you a nifty tool to create documents collaboratively while you talk. If you are using Jitsi for somewhat serious needs, then I think it is a good addition to have.
