I found myself in a similar boat (converted a personal ChatGPT sub to a Business Account shared with my partner). I ended up using Claude it write a chrome extension to just walk every chat in the side navbar and dump it to a sqlite database (when I then used for my own RAG purposes). Thanks for publishing your work.

Thank you very much, this is very useful and helpful. I will be using this and I missed it before. I want to acknowledge your effort.
