2. Go chapter by chapter: Paste one chapter at a time into the summarizer
3. Select Bullet Points mode: Gets you key facts, arguments, and definitions
4. Save each chapter's summary: Copy to your notes app
5. Combine: Once all chapters are summarized, paste the combined bullet lists and summarize again for an overall book summary

Best Practices for Different Book Types

Textbooks (Studying)

Use Bullet Points mode. Focus on definitions, formulas, key concepts, and examples. One chapter at a time. Convert the output into flashcards for active recall. This cuts study prep from hours to minutes — you still need to understand the material, but the summary gives you structured notes.

Non-Fiction (Personal Development, Business)

Use Detailed mode for the introduction and conclusion (these contain the core thesis). Use Bullet Points for middle chapters (supporting arguments and evidence). This gives you the big picture + key details without reading every page.

Research / Academic

For papers and academic books, summarize the abstract, introduction, results, and discussion sections separately. Skip methodology unless it is relevant to your work. Use the paraphraser to rework summaries into your own voice for literature reviews.

Fiction (Book Reports)

AI summarizers work for fiction but miss subtext, themes, and symbolism. Good for: plot summaries, character lists, chapter-by-chapter events. Not good for: thematic analysis, literary criticism, author intent. For book reports, use the AI summary as a plot skeleton and add your own analysis.

The Two-Pass Method for Entire Books

Summarizing a whole book in one paste does not work well — too much text, too much lost nuance. Instead:

1. Pass 1: Summarize each chapter to bullet points (30 sec each)
2. Pass 2: Combine all chapter bullets and summarize the combined text to a Brief overview

This gives you both: chapter-level detail (from Pass 1) AND a book-level overview (from Pass 2). A 20-chapter book takes about 15 minutes total.
