Give me your apps that allow me too upload a pdf file of a book and then talk to it I don’t look for a GPT wrapper around files. I have tried it and it sucks, hallucinates a lot and never gives me the answer based solely on the book If I have my book saying that in order to achieve this you have to do 1, 2, and 3, then when I ask the app a question related to this portion of the book, it must answer based on the book and adjust according to the question without adding any additional general AI knowledge based on training of that model I haven’t found anything similar to this, almost feel like I need to create such an app myself. But before that I want to ask you redditors Thank you
