How to Turn Any PDF into a Quiz with AI (Free + Paid Methods)
Why Turn a PDF into a Quiz?
Before the tools, the science: a landmark study in Psychological Science found that students who self-tested after reading retained 50% more material a week later than students who re-read the same content. This is the testing effect — and it's one of the most replicated findings in cognitive psychology.
Turning your PDF into a quiz doesn't just save time. It actually changes how well you learn.
Method 1: Prismer (Best for Students and Researchers)
Best for: Research papers, textbook chapters, lecture notes Price: Free (3 sessions/month) / $9.90/month Time: About 60 seconds
Prismer is purpose-built for turning any content — PDFs, videos, links, or typed topics — into learning materials. The output isn't just a list of questions; it includes quizzes, presentation slides, and structured study notes in one go.
Step-by-step:
- Go to prismer.app and create a free account
- Click 「New Learn」 on your dashboard
- Upload your PDF or paste the content link
- Prismer analyses the document and generates:
- Multiple choice questions testing key concepts
- Presentation slides summarizing the main points
- Structured notes breaking down the material
- Start the quiz directly in the browser — no export needed
What makes Prismer different: The questions test conceptual understanding, not just surface recall. Instead of asking "What is X?" it asks "Why does X happen?" or "What would happen if Y?" — the kind of questions that actually appear on exams.
Best for: University students, PhD researchers, and professionals studying complex material where understanding matters more than pure memorization.
Method 2: ChatGPT (Best Free Option for Any PDF)
Best for: Quick quiz generation from any PDF Price: Free (GPT-4o with file uploads) Time: 2–5 minutes
ChatGPT can read PDFs directly and generate quiz questions on demand. It's free, flexible, and works for any subject.
Step-by-step:
- Open chatgpt.com (free account works)
- Start a new conversation and click the paperclip icon to upload your PDF
- Once uploaded, paste this prompt:
Based on this PDF, create a 10-question multiple choice quiz that tests understanding of the key concepts. For each question:
- Write 4 answer options (A, B, C, D)
- Mark the correct answer
- Add a one-sentence explanation of why it's correct
Focus on conceptual understanding, not just definitions.
- ChatGPT generates the quiz instantly
- Copy the questions into a doc, or ask it to generate more
Pro tip — better questions with a better prompt:
If the default questions feel too easy or too surface-level, add this to your prompt:
Make the questions exam-difficulty. Include some questions that require applying the concept to a new scenario, not just recalling it.
Limitations:
- You have to manually manage and track your answers
- No spaced repetition — you'll need to re-quiz yourself manually
- ChatGPT sometimes generates plausible-sounding but incorrect explanations (always verify)
- File size limit applies
Method 3: NotebookLM (Best for Multiple PDFs at Once)
Best for: Synthesizing quiz questions across multiple documents Price: Free Time: 3–5 minutes
Google's NotebookLM lets you upload multiple PDFs and generate quizzes that draw from all of them at once — useful for exam revision where your material is spread across several documents.
Step-by-step:
- Go to notebooklm.google.com
- Create a new notebook and upload your PDFs as sources
- In the chat panel, type:
Create a 10-question quiz based on the key concepts across all my sources. Include the correct answer and a brief explanation for each question.
- NotebookLM generates questions with inline citations showing which source each question came from
What it does well: Every answer is cited back to a specific page in your source document — so you can immediately check the original context if you get a question wrong.
Limitations:
- No built-in interactive quiz mode — it generates text you read, not an interactive experience
- Questions tend toward factual recall rather than conceptual application
- No spaced repetition or progress tracking
Method 4: Quizgecko (Dedicated PDF-to-Quiz Tool)
Best for: Quick quizzes with an interactive interface Price: Free (limited) / $10/month Time: Under 2 minutes
Quizgecko is a dedicated quiz generation tool that accepts PDF uploads and creates interactive quizzes you can take directly in the browser — or share with others.
Step-by-step:
- Go to quizgecko.com
- Click 「Create Quiz」 → 「Upload File」
- Upload your PDF and select question type (multiple choice, true/false, short answer)
- Choose how many questions you want (5–50)
- Click 「Generate Quiz」
- Take the quiz in the browser or share via link
What it does well: Fast, clean interface. Good for sharing quizzes with study groups or classmates.
Limitations: Free tier is limited to shorter documents and fewer questions. Quality varies on complex academic content.
Method 5: Anki + AI (Best for Long-Term Memorization)
Best for: Material you need to remember for months or years Price: Free (Anki desktop) + free AI tools Time: 10–15 minutes to set up
If you're studying for medical boards, language proficiency exams, or any high-stakes test that requires retaining large amounts of information over a long period, Anki's spaced repetition algorithm is the gold standard. You can use AI to generate the cards, then import them into Anki.
Step-by-step:
- Upload your PDF to ChatGPT and use this prompt:
Convert the key concepts from this PDF into Anki flashcard format. For each card: Front: [question or concept] Back: [answer or explanation]
Generate 20 cards covering the most important points. Format them exactly like this so I can import them.
- Copy the output into a
.txtfile, formatted as:
Question 1 [tab] Answer 1 Question 2 [tab] Answer 2
(Tab-separated, one card per line)
- In Anki, go to File → Import and select your
.txtfile - Anki will schedule the cards using its spaced repetition algorithm
Why this works for long-term retention: Anki shows you each card at precisely the right moment — just before you'd forget it. Over months, this dramatically reduces the study time needed to maintain retention.

Tips for Better AI-Generated Quiz Questions
Regardless of which tool you use, the quality of your quiz depends partly on how you guide the AI.
1. Specify the difficulty level
Add to your prompt: "Make the questions exam-difficulty — they should require applying the concept, not just recalling it."
2. Focus on the concepts that matter most
If your PDF has 50 pages, tell the AI which sections matter: "Focus on pages 10–25, specifically the methodology section."
3. Include application questions
Add: "Include at least 3 questions that ask me to apply the concept to a new scenario."
4. Ask for explanations
Always request explanations for correct answers: "For each question, explain in one sentence why the correct answer is right." This is what makes self-testing actually educational rather than just a pass/fail check.
5. Test yourself immediately, then again after 24 hours
The testing effect is strongest when you space your study sessions. Take the quiz once right after reading, then again the next day. The questions you get wrong the second time are the ones that need more attention.
The Right Tool for the Right Goal
The best method depends on why you're studying:
「I need to pass an exam next week」 → ChatGPT for speed, Quizgecko for interactive practice

「I'm studying from 5 different PDFs at once」 → NotebookLM for cross-document synthesis
「I want to share a quiz with my study group」 → Quizgecko for shareable links
Frequently Asked Questions
Can I turn a PDF into a quiz for free? Yes. ChatGPT (free tier), NotebookLM, and Prismer (3 free sessions/month) all allow free PDF-to-quiz conversion. Anki is free on desktop. You don't need a paid subscription to get started.
How many questions should I generate from a PDF? For a 10–20 page document, 10–15 questions is a good target. More isn't always better — a focused set of well-written questions on the core concepts is more useful than 50 surface-level recall questions.
What's the best AI to make a quiz from a PDF? For interactive quizzes with conceptual depth: Prismer. For free, flexible generation with no account needed: ChatGPT. For multiple PDFs with cited answers: NotebookLM. For long-term retention: Anki with AI-generated cards.
Can AI generate quiz questions from scanned PDFs? It depends on the tool. Scanned PDFs (images of pages) require OCR before AI can process the text. Prismer and ChatGPT both handle most scanned PDFs. If the scan quality is poor, text extraction may be incomplete.
How accurate are AI-generated quiz questions? For most academic content, AI-generated questions are accurate. However, always verify answers for highly technical, mathematical, or specialized content — AI can occasionally misinterpret nuanced material. NotebookLM is generally the most reliable because it cites the specific source passage for each answer.
Can I turn a video lecture into a quiz, not just a PDF? Yes. Prismer accepts video links (YouTube, etc.) in addition to PDFs and generates quizzes from video content. For other tools, you can first generate a transcript using a tool like Otter.ai or YouTube's automatic captions, then feed the transcript as text.
