Whole books and hundred-page PDFs are too long to paste into a chatbot — but not for PDF.chat. It indexes the entire book and retrieves the most relevant pages for each question, so length is never a problem.

Ask about a chapter, a character, an argument or a specific passage, and get an answer grounded in the text with a page citation.

How to chat with a book

Upload the book

An ebook (EPUB), a long PDF, or any large document.

Ask across the whole thing

PDF.chat finds the relevant pages for your question, however long the book is.

Explore chapter by chapter

Summarize a section, trace a theme, or find a quote — all cited.

Common uses

Chat with a textbook or non-fiction book while you study
Find and quote a passage from a long ebook
Summarize a chapter or part of a long report
Ask questions across a hundred-page document or docket

Frequently asked questions

Yes — it indexes the whole book and pulls the relevant passages for each question instead of needing the entire text at once.

Yes — "what happens in chapter 7?" or "summarize part two" and it answers from those pages.
