How to ask AI about a whole book — and why pasting it in is not enough
To ask AI a real question about a whole book — where the argument turns, what the author walks back, whether chapter nine contradicts chapter two — the AI has to read the book the way you would: look at the table of contents, decide which chapters the question needs, read those in full, and go back for another if the first did not settle it. Pasting the whole book in and searching chopped-up fragments both fail at exactly these questions.
Every AI reading tool has to decide what happens when the material is longer than the model can handle well. That decision is invisible in the answer, and it determines whether the answer can be trusted.
