Total noob here, so forgive me if this question is dumb or naive. I'm interested in pursuing collaborative fiction writing with AIs. Does what you're saying here imply that, in principle, I can sort of artificially increase ChatGPT's memory of whatever world I'm working with it to write about, by developing a plug-in which queries info about my story that I've written including character info, setting details, and previous chapters? If true, this would help the whole process immensely...
