How an AI quiz from a PDF helps you study

Many students want an AI quiz generator from PDF files because rereading a 40-page chapter rarely shows what you actually remember. Testing yourself on the material is more effective, but writing good questions by hand takes time you may not have before an exam.

  • Questions are based on the pages you upload, so you practice the content your instructor actually covers.
  • Every question includes an explanation, which helps you learn from mistakes instead of just marking them wrong.
  • The free plan gives 3 generations per month, with no credit card needed to start.
  • Students with a school email get 40% off Plus, which includes unlimited generations and PDF or DOCX export.
Example intro biology quiz questions
What organelle produces most of a cell's ATP?Mitochondria. They carry out most of cellular respiration, which generates ATP.
True or false: plant cells lack a cell membrane.False. All cells are bounded by a plasma membrane, and plant cells also have a cell wall outside it.
Which molecule carries genetic instructions out of the nucleus?Messenger RNA (mRNA). It is transcribed from DNA and carries the code to ribosomes for translation.
What is the main job of ribosomes?Protein synthesis. They translate mRNA into a chain of amino acids.
In diffusion, which direction do molecules move?From higher to lower concentration. This happens without energy input because it follows the concentration gradient.

Multiple-choice, true/false, and short answer

Choose the question type that fits your course. Each question comes with an explanation so a wrong answer teaches you something.

Built from your own material

Upload PDF, DOCX, PPTX, text, or a photo of a textbook page. The questions come from the pages you gave it, not a generic question bank.

Export when you need it

Study in the browser on the free plan. Plus adds PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML for learning management systems.

How it works

Upload your PDF

Add a chapter, lecture deck, or set of notes. Photos of pages are read with text recognition.

Pick a question type

Choose multiple-choice, true/false, or short answer, and how many questions you want.

Answer and review

Take the quiz, read the explanations for anything you missed, and generate a new set when you want more practice.

DeckOwl reads the text in your PDF and writes questions about the key terms, processes, and claims in it. Multiple-choice and true/false questions give quick checks, while short-answer questions make you explain an idea in your own words.

Frequently asked questions

How many practice questions should I answer per session?

Ten to twenty focused questions is a good target for one session. Short, frequent quizzes help you remember more than one long cram session.

What should I do with questions I got wrong?

Read the explanation, then try the same idea again a day or two later without looking at the answer. Repeating missed questions after a delay is one of the most reliable ways to strengthen memory.

Can I export the quiz to PDF or Moodle?

PDF and DOCX export are included in Plus. QTI 2.1 and Moodle XML export are included in Pro. The free plan lets you study in the browser without exports.

Do I need a credit card to try it?

No. You can start on the free plan with 3 generations per month and add a paid plan later if you need more.
