1. Suppose the exam is on Monday

Suppose we are Ritika, a second-year B.Pharm student in Nagpur. Our Pharmacology chapter on antibiotics is a 38-page PDF from our professor. We paste it into a chat and ask: Summarise this chapter.

A typical answer (yours will be similar, not the same):

This chapter discusses antibiotics, which are drugs used to treat bacterial infections.
It covers their classification, mechanisms of action, side effects and resistance...

It is correct, but useless for the exam. It does not tell us which antibiotics, which mechanism goes with which class, or where in the PDF to read more. Worse, if the AI adds a drug that is not in our chapter PDF, we would not know.

Grounded notes fix this:

Grounded notes are made only from the sources you give, with a citation that shows exactly where each point came from.

That is what Gemini Notebook is built for.

2. Gemini Notebook (formerly NotebookLM) in 5 minutes

Google renamed NotebookLM to Gemini Notebook on 16 July 2026. It is the same free, standalone tool. The address is notebook.google, and the old notebooklm.google.com link redirects there. You can also open your notebooks inside the Gemini app.

How it works:

1. You create a notebook for one subject or topic.
2. You add sources: PDFs, Google Docs, Google Slides, website links, YouTube links and audio files.
3. You ask questions in the chat. Answers come from your sources, with small numbered citations. Click a citation to see the exact passage.
4. You can create study material from the sources: reports, flashcards, quizzes, mind maps and Audio Overviews (a podcast-style conversation between two AI voices).

Free plan limits (Gemini Notebook help pages, checked 23 October 2026):

Paid Google AI plans give higher limits. Copy-protected PDFs cannot be added as sources. Google's help page says your data is not used to train Gemini Notebook unless you give feedback.

3. Worked example 1: chapter notes with citations

Steps:

1. Go to notebook.google and sign in with your Google account.
2. Select Create new (a new notebook). Name it Pharmacology – Antibiotics.
3. Add your source: upload the chapter PDF. (Use your own notes or the PDF your college shared with you for study.)
4. Wait until the source is processed. You may see a short automatic summary.
5. In the chat box, paste:

Make exam revision notes from this chapter only.
Format:
1. A table: Antibiotic class | Example drugs | How it works (one line) | One key side effect.
2. 5 "must remember" points.
3. 3 points students often confuse, and how to tell them apart.
Cite the source for every row and point. If something is not in the PDF, do not add it.

Expected output (yours will be similar, not the same):

| Antibiotic class | Example drugs        | How it works                         | Key side effect         |
|------------------|----------------------|--------------------------------------|-------------------------|
| Penicillins      | Amoxicillin [1]      | Blocks bacterial cell wall formation | Allergic reactions [2]  |
| Macrolides       | Azithromycin [3]     | Stops bacterial protein synthesis    | Stomach upset [3]       |
| Fluoroquinolones | Ciprofloxacin [4]    | Blocks bacterial DNA copying         | Tendon problems [5]     |
...

Students often confuse:
1. Bactericidal vs bacteriostatic: kills bacteria vs stops their growth [6]
...

6. Click 3 citations. Each one opens the exact passage in your PDF. If a point has no citation, or the citation does not say it, cross it out.
7. Select Save to note (or copy the notes into your own document).

Why the table works: it forces the chapter into the 4 facts your exam asks about, side by side. Comparing classes in a table is how you remember them.

4. Worked example 2: practice questions from your PDF

In the same notebook, ask:

Make 10 exam-style questions from this chapter only:
- 5 short-answer questions (2 marks each)
- 3 multiple choice questions with 4 options
- 2 long-answer questions (5 marks each) with the points the answer must include
Do not show the answers yet. When I reply with my answers, check each one against the PDF and cite the page.

Expected output, part (yours will be similar, not the same):

Short answer (2 marks):
1. Define antibiotic resistance and give one cause mentioned in the chapter.
2. Name one penicillin and state how it acts on bacteria.
...
Multiple choice:
6. Which class of antibiotics stops bacterial protein synthesis?
   A. Penicillins  B. Macrolides  C. Fluoroquinolones  D. None of these
...

Now answer them yourself, in writing, then paste your answers:

My answers: 1. Resistance means bacteria are no longer killed by the drug; cause: not completing the course. 2. ...

Expected feedback (yours will be similar, not the same):

1. Correct. The chapter also mentions overuse of antibiotics as a cause [7]. Add it for full marks.
2. Partly correct. You named amoxicillin, but the mechanism is "blocks cell wall formation" [1], not "kills DNA".

You can also use the built-in Quiz and Flashcards options in the notebook (free: 10 per day each). The chat method is more flexible because you choose the exam pattern.

5. Worked example 3: a two-person Audio Overview

An Audio Overview is a short, podcast-style conversation between two AI voices that discuss your sources. It is great for revision while travelling, and the free plan allows 3 per day.

Steps:

1. In your notebook, find Audio Overview in the side panel (often called Studio).
2. Before you generate, look for an option to customise it, and type a focus, for example:

Focus on comparing the antibiotic classes and on antibiotic resistance. The listener is a B.Pharm student revising for an exam. Keep it under 10 minutes.

3. Select Generate. It can take a few minutes; you can keep working.
4. Play it, or download it to listen offline.

What you will hear (yours will be similar, not the same): two voices talking naturally: "So the big idea in this chapter is that each antibiotic class attacks bacteria in a different way..." "Right, and the penicillins go after the cell wall..."

Use it well:

• Listen after you have read the chapter once. It is revision, not a replacement.
• Pause when they mention something you cannot explain, and note it.
• The voices can still simplify or slightly misstate a point. If something surprises you, check it in the notes with citations.

6. The same thing in a ChatGPT project

If you prefer ChatGPT, use a project (you met projects in the ChatGPT chapter and the "Save your best prompts" chapter). The free plan allows up to 5 files per project.

Steps:

1. In ChatGPT, select New project and name it Pharmacology.
2. Add the chapter PDF to the project files.
3. Add project instructions:

In this project, answer only from the files I added. For every point, give the page number.
If something is not in the files, say "Not in the PDF". Use simple English and tables for comparisons.

4. Use the same prompts as in worked examples 1 and 2.

Difference from Gemini Notebook:

For exam study from your own PDFs, Gemini Notebook is the better first choice. ChatGPT is fine for one or two chapters, especially if you already use it every day.

7. Study habits that make AI notes stick

1. One notebook per subject, not one per exam. Add each chapter as a new source as the course goes on.
2. Read first, then ask. Skim the chapter once yourself so you know what good notes should contain.
3. Test, do not just read. Cover columns, answer quiz questions in writing, explain aloud.
4. Check 3 citations every time. If a citation does not match, trust the PDF, not the AI.
5. Keep your own words. Rewrite the "must remember" points in your own notebook by hand. Writing helps memory.
6. Respect the material. Upload notes and PDFs you are allowed to use for study. Do not upload paid books you do not own, or share notebooks of copyrighted material publicly.

8. Compare the tools for PDF study

9. Worked example 4: deeper Audio Overview — one chapter podcast

Example 3 introduced Audio Overview. Here we go deeper. Suppose Monday's exam covers only Chapter 4 of your PDF. In NotebookLM (Gemini Notebook), make a notebook with that PDF only (health-check: EXPANDOCT23-NOTEBOOKLM-AUDIO-CHAPTER). Free limits change — check Google's NotebookLM page.

Steps:

1. New notebook → upload only the Chapter 4 PDF (or a PDF you split yourself).
2. Click Audio Overview. Choose a shorter / focused overview if the UI offers formats.
3. Listen once without notes. Listen again and pause to write 10 bullets by hand.
4. In the notebook chat, ask:

From my sources only, list 10 exam-style questions with one-line answers.
Cite the section heading for each. If not in the PDF, say 'not in source'.

Expected output (yours will be similar, not the same): a podcast-style overview you can replay on the bus, plus a cited question list.

10. Worked example 5: CA circular Q&A notebook

Suppose an accounts intern uploads a public ICAI or GST FAQ PDF (public file only — not a client's private notice). Ask NotebookLM questions and demand citations.

Prompt:

What does this circular say about late fee? Quote the line and give the heading.
If the circular is silent, say so. Do not invent sections.

Expected output (yours will be similar, not the same): answers with clickable citations back into the PDF. This is study help, not legal advice.

11. Worked example 6: AWS study-plan notebook + audio

Cross-link idea: upload your own notes PDF for AWS Cloud Practitioner / AI Practitioner topics you already study on this site. Generate Audio Overview for commute revision, then ask for a 7-day study plan from sources only.

Using only my uploaded notes, make a 7-day study plan with 1 hour per day.
Day list + 3 bullet topics each day. No new exam fees or dates inventing.

12. Beginner mistakes and quick fixes

13. Try at home

Recap

Make one notebook for your hardest subject today, add one chapter, and do the self-test. You will know exactly what you know, and what you only think you know.
