Summarize a textbook chapter section by section
Forty pages assigned for Thursday, and you need to know what actually matters. Snap the pages or attach the chapter PDF, and your agent follows the book's own headings to summarize each section in a few lines, pulls out the bold terms, ranks the ideas most likely to be tested and ends with review questions that check you really understood it.
The prompt
- Summarize this textbook chapter: [CHAPTER FILE OR PHOTOS]. It is chapter [CHAPTER NUMBER AND TITLE] of [TEXTBOOK AND COURSE]. Follow the book's own headings and summarize each section in 3–5 sentences in plain words, keeping key numbers, names and formulas. Then list every bold or key term with a one-line definition and the page it is on, the 5 ideas most likely to be tested and why, and how this chapter connects to the previous one. End with 8 review questions (mix of recall and "explain why"), answers on a separate page. Total length about [LENGTH]. Send it as a [FORMAT].
What to change
- [CHAPTER FILE OR PHOTOS]: Attach the chapter as a PDF, or photos of each page in order. Scanned pages are read with OCR.
- [CHAPTER NUMBER AND TITLE]: E.g. "5, Supply and Demand".
- [TEXTBOOK AND COURSE]: E.g. "Principles of Economics, ECON 101". Helps the agent keep the course's terms.
- [LENGTH]: E.g. "2 pages", "one page", "500 words".
- [FORMAT]: "PDF", "Word file" or "message I can read on my phone".
Example result
- Chapter 5: Supply and Demand (ECON 101)
- 5.1 Demand
- Demand shows how much of a good buyers are willing and able to buy at each price. The law of demand says that, other things equal, quantity demanded falls as price rises, so the demand curve slopes down. A change in price moves you along the curve.
- 5.2 What shifts demand
- The whole curve shifts when something other than price changes: income, prices of related goods (substitutes and complements), tastes, expectations and the number of buyers. For a normal good, higher income shifts demand right; for an inferior good, left.
- 5.3 Supply
- Supply shows how much sellers will offer at each price. The law of supply says quantity supplied rises with price, so the curve slopes up. Supply shifts with input costs, technology, expectations, taxes and subsidies, and the number of sellers.
- 5.4 Equilibrium
- The market settles where quantity demanded equals quantity supplied. Above that price there is a surplus that pushes the price down; below it, a shortage pushes it up.
- 5.5 Changes in equilibrium
- To analyze any event: decide which curve shifts, in which direction, then compare the old and new equilibrium price and quantity. If both curves shift, one of price or quantity is ambiguous.
- Key terms
- • Quantity demanded: the amount buyers want at one specific price (p. 112)
- • Substitutes: goods used in place of each other; a price rise in one raises demand for the other (p. 116)
- • Complements: goods used together (p. 116)
- • Equilibrium price: the price where supply and demand meet (p. 124)
- • Shortage / surplus: quantity demanded above / below quantity supplied (p. 125)
- 5 ideas most likely on the test
- • 1. "Change in demand" vs "change in quantity demanded": the most common exam trap
- • 2. Normal vs inferior goods
- • 3. Reading surpluses and shortages from a graph
- • 4. The three-step method for analyzing an event
- • 5. Double shifts and the ambiguous variable
- Link to chapter 4
- Chapter 4 introduced markets and opportunity cost. This chapter turns that into a model of how prices form.
- Review questions
- • 1. Why does a fall in the price of coffee not shift the demand curve for coffee?
- • 2. Coffee and tea are substitutes. What happens to the market for tea if coffee gets more expensive?
- • 3. Supply rises and demand falls. What happens to price? To quantity?

Tips for a better result
- Read the summary before the chapter, not instead of it. You will read faster and notice what matters.
- Keep page numbers next to key terms so you can jump back to the full explanation and examples.
- Take flat, well-lit photos of each page; curved pages near the spine are the hardest for OCR.
- Set a weekly to-do: "every Sunday, summarize the chapter I attach and send me 5 questions on Wednesday" to keep up all term.
summarize a textbook chapter: FAQ
- Can it summarize a chapter from photos of the book? Yes. It reads photos with OCR or by looking at the image. Send pages in order, and say if any are missing.
- How long is the summary? You choose. A 30–40 page chapter usually fits well into 1–2 pages, plus the key terms and questions.
- Can it summarize an e-book or a PDF textbook? Yes, if you have the file and it is not password-protected. Attach just the chapter you need; uploads can be up to 50 MB each.
- Is a summary enough to pass the exam? It is a fast way to review, but examples and practice problems in the full chapter matter too. Use the summary to guide your reading and revision.
