I am working on the same thing. I pulled a few hundred papers I read in the last couple of years and my full online comment history going back 10 years, extracted text and split into chunks. Then embedded the chunks with sentence transformers and indexed with annoy. This allows me to get text snippets by query and add them to the prompt. OpenAI hints at this functionality because it included "Browsing: disabled" in the prompt. Probably in the future they are going to flip the switch.
