Not gpt, a few open-source LLMs I jerry rigged using pain and suffering then feed pictures of hand made written text I’ve been writing for a few years now. 😅 My texts draw from many sources and books.
Like my incomplete notes on the American education system which draws heavily from “The smartest kids in the world and how they got that way” by Amanda Ripley, as well as many of my own experiences and ideas of living though it. The AI just helps bridge the ideas and format from my trash handwriting into something actually usable.
