What the summary covers
A book summary is only useful if it keeps the structure of the argument. With the Book / long text document type, the summary gives:
- The central thesis (non-fiction) or the premise and plot (fiction).
- The structure — one line per part or chapter when the book makes them identifiable.
- The key ideas or turning points, in the order the book develops them.
- Notable examples, studies or stories the author uses to make the case.
- The conclusion or ending, and what the author asks the reader to do or think.
The default length on this page is Comprehensive (around 800 words, with headings). Choose Key points for a one-screen recap of the ideas worth keeping.

Example of the output format
Illustrative example for a fictional non-fiction book:
Central thesis. Small, consistent routines beat occasional bursts of motivation (p. 3). Part I — Why routines work (ch. 1-3). The author contrasts goal-setting with system-building, using the case of a cycling team (p. 21). Part II — Building them (ch. 4-9). Four steps: make the cue obvious, the action easy, the reward immediate, the progress visible (p. 58). Conclusion. Progress compounds; the reader is asked to design one routine before finishing the book (p. 241).

Limits and fair use
Summaries are no substitute for the experience of reading a novel, and nuance is always lost in compression. Upload only PDFs you are allowed to use — your own purchases, public-domain books, open-access titles or documents you received for your work. Very long books (over 300 pages) should be split into parts, for example with a free PDF splitter.
Frequently asked questions
Can it summarize a 500-page book?
The free tool accepts up to 300 pages per PDF. Split a longer book into two or three files (by part) and summarize each one; you can then ask for key points of each part.
Does it work for novels?
Yes. For fiction the summary covers the premise, main characters, plot by part, major turning points and the ending. Choose Short if you want to avoid detailed spoilers.
Can I summarize EPUB or Kindle books?
The tool reads PDF only. If you have an EPUB without DRM, export or print it to PDF first.
Can I get a summary per chapter?
Ask in the Q&A tab: “Summarize chapter 3 in 10 bullet points.” The answer is based on the text of that chapter and cites its pages.
Which languages?
Books in any common language. Summaries can be written in 20 languages, so you can summarize a French essay in English, for example.
