There are a lot of open source tools for summarizing/comparing/chatting with lengthy documents. Most of them use something like pinecone to store embeddings from your document(s), although some let you store embeddings locally (e.g. BriefGPT). I've tried some of them with medium sized docs (~20 pages), and found them to work pretty well. Not sure whether the performance drops off as you move into full sized novel length docs though. Might be good to test some of them on a book you're very familiar with before trusting them to accurately summarize unknown materials for you. Here are some links to the gpt-document tools I have bookmarked. Some of them do have online demos, but you'll typically have more flexibility if you implement them on your local machine. https://gptdoc-summarizer.streamlit.app/ https://chat.vectorhub.org/ https://knowledgegpt.streamlit.app/ https://vault.pash.city/ https://gptdoc-summarizer.streamlit.app/ https://github.com/imartinez/privateGPT https://github.com/e-johnstonn/BriefGPT https://github.com/dissorial/doc-chatbot https://github.com/PromtEngineer/localGPT https://github.com/Anil-matcha/ChatPDF More on reddit.com

For anyone looking for an option that works on your phone, I found an app called AISlide.

Its drawback at the moment is that it doesn't have a web version, it's only an app More on reddit.com
