deep-reader

# Deep Reader Read long books and papers the way a careful human researcher does: skim for structure first, read deeply chapter by chapter with notes as you go, then synthesize from the notes — never the raw text — at the end. The method comes from Adler's *How to Read a Book*, SQ3R's Recite step, and Keshav's three-pass method for papers. ## Why multi-pass, why notes An LLM's attention dilutes over long contexts, and it loses track of material buried in the middle of a big prompt ("lost in the middle"). Loading a 500-page book into one context and asking questions about it produces answers that quietly forget chapter 3 by the time you're discussing chapter 12. The fix is the same one human researchers use: never hold the whole book in working memory at once. Read it in passes — first for structure, then chapter by chapter for content — and externalize what you learn into note files as you go. The notes become the durable memory; the book itself only needs to be back in view when you're actively reading a specific chapter or verifying a specific claim. Page numbers are the coordinate system that makes every claim traceable back to the source, in this session or a later one. ## Two modes - **overview** — Adler's inspectional pass only: a book map plus a goal-directed summary of the chapters that matter most to the reader's purpose. Fast, no per-chapter notes. - **study** — the full pipeline: reading purpose → inspectional map → chapter-by-chapter analytical notes w...
