# Textbook & Lecture Notes Summarizer

Turn a textbook chapter, a lecture handout or a course PDF into revision notes you can actually study from — key concepts with one-line definitions, the formulas, dates and names to remember, how the ideas connect, and three questions to test yourself.

## Key facts

- Output is revision notes, not a generic summary: concepts, definitions, formulas, dates, names, links between ideas.
- Ends with 3 self-test questions to check what you remember.
- Works on textbook chapters, lecture notes, course handouts and exported slides.
- Ask the document to explain a concept again, more simply, or with an example from the text.
- Free, no account; summarize in your study language.

## What you get

Studying from a summary only works if it keeps what an exam asks for. With the **Course / textbook** type, the output is organised as revision notes:

- **Key concepts**, each with a one-line definition taken from the text.
- **Formulas, dates, names and numbers** that are likely to be asked.
- **How the ideas connect** — cause and effect, steps of a process, comparisons.
- **Three self-test questions** at the end.

## How to turn a chapter into revision notes

1. **Upload one chapter or one lecture** — Smaller units give sharper notes than a whole textbook at once.
2. **Keep “Course / textbook” selected** — Bullet points are preselected on this page; choose Detailed for dense chapters.
3. **Read the notes, then answer the self-test questions** — Without looking first: this is where learning happens.
4. **Ask for explanations** — “Explain the difference between mitosis and meiosis as it is described here”, “Give the example the chapter uses for elasticity”.
5. **Download the notes** — Save them as Markdown into your notes app or flashcard tool.

## Study techniques that work with it

- **Summarize after reading, not instead of reading.** Read the chapter once quickly, then use the notes to review — comparing your memory with the notes is the most effective step.
- **Turn self-test questions into flashcards.** Ask for ten more questions in the Q&A tab: “Give me 10 exam-style questions on this chapter with answers and pages.”
- **Explain it back.** Ask the tool to check your explanation: “Is this a correct summary of section 2: …?”.
- **Review the cited pages** for anything you got wrong.

> **Exam next week?** — Upload your first chapter and get revision notes with self-test questions.

## Limits

Diagrams, chemical structures and handwritten annotations are not read. Formulas are extracted as text and can lose their layout — check them in the original. Notes are as good as the source: if your lecture slides contain only keywords, ask questions about the related textbook chapter instead.

## FAQ

### Can it summarize lecture slides?

Yes. Slides exported to PDF work; for decks with very little text, the slide-deck summarizer reconstructs the storyline instead.

### Can it create flashcards?

Ask in the Q&A tab for question-and-answer pairs from the chapter, then copy them into your flashcard app.

### Is it allowed to use this for studying?

Using summaries to review is a normal study practice. Submitting AI-generated text as your own work may break your school's rules — use the notes to learn, and write assignments yourself.

### Can it explain difficult passages?

Yes. Ask “Explain the passage on page 34 in simpler words” — the answer is based on the chapter's own content.

### Does it work in my language?

Courses in any common language can be summarized, and the notes can be written in any of 20 output languages.
