Maybe the feature already exists, but I can't seem to find it. Open WebUI can do this (Dave had recently shown how to do this), but it's quite "clunky", because I need to update its Knowledge, every time I added something new.
My usecase is to have a setting on BMO Chatbot that can be turned on (ala /ref on) to reference a certain folder in my Obsidian database.
/folder_ref ~/WK32_MeetingMinutes
And this would aggregate all the information in different notes, that're in that particular folder, to answer the prompt we give the BMO Chatbot.
Alternatively, we link the BMO Chatbot Profile, to a certain folder in our Obsidian filestructure, and can switch it easily, if needed.
