Trying to figure out a way to push selected ChatGPT prompts and responses to a Notion database. I do not need entire conversations saved, simply certain prompts and responses. I am not experienced in working with APIs but am learning and would like to build this as a Chrome extension or even something to run locally.

There are currently many extensions available with functionality similar to what you described.
