Hey @markkerrigan, please check out the Expanded Chat-GPT plugin to see where I’ve gotten with it, and feel free to post here and/or there detailing thoughts on your use cases, as I am formulating next steps 
also feel free to ask specific questions about my own process, as I have been developing new habits since implementing AI into my knowledge base.
I have found there is no need to go through additional training of models, but rather an extensive system prompt going over important Tiddlywiki syntax and explaining its context as an agent within Tiddlywiki has been sufficient to yield consistent results.
