Does anyone have recommendations for tools to use for a personalized AI assistant? By which I mean that the data remains your own. It could be notes you have taken over the years, standard operating procedures, customer interactions, whatever. But the key thing is that it is your own and is not shared (as it would be with ChatGPT). For example, I have collected a huge amount of information in Evernote and documents over the years, and it would be nice to treat that as a knowledge base.
