Why a free AI quiz generator from PDF helps you study
Students often need a free AI quiz generator from PDF that works on the exact readings their course assigned, not on generic practice sets. Upload the chapter, lecture slides or notes you already have, and the tool writes questions based on that material.
- Questions built from your own PDFs, slides and notes
- Multiple-choice, true/false and short-answer formats with explanations
- Free plan with 3 generations a month and browser study
- Students get 40% off with a school email
Three question types
Multiple-choice, true/false and short-answer questions, each with an explanation of the correct answer.
Works from your own files
Upload PDF, DOCX, PPTX, plain text or photos of pages, which are read with text recognition.
Study in the browser
The free plan lets you take quizzes right away in the browser, and no credit card is needed to start.
How it works
Upload your material
Add a PDF, slide deck, Word document, notes or a photo of a page.
Choose your question types
Pick multiple-choice, true/false or short-answer questions for your quiz.
Take the quiz and read the explanations
Answer each question, then read why the right answer is right to review what you missed.
Explanations matter as much as the questions. When a wrong answer comes with a short reason, you learn the concept behind it, which is more useful than a score alone. Mixing multiple-choice, true/false and short-answer questions also tests recognition and recall.
The free plan includes 3 generations a month and lets you study in the browser. Exports are paid features: Plus adds PDF, DOCX, Anki and CSV export along with unlimited generations, and Pro adds QTI 2.1 and Moodle XML export.

Frequently asked questions
How many practice questions should I make from a chapter on World War I causes?
Start with 10 to 15 questions per chapter so you cover the alliances, militarism, imperial rivalries and the June 1914 assassination. Then add more questions on the topics you miss most often.
Are short-answer questions better than multiple choice for studying history?
Short-answer questions force you to recall and explain a cause in your own words, which builds stronger understanding. Multiple-choice questions are quicker for checking whether you recognize key terms and dates.
Can I export my quizzes on the free plan?
No, the free plan lets you study in the browser but does not include exports. PDF, DOCX, Anki and CSV export are available on Plus, and QTI 2.1 and Moodle XML export are on Pro.
Do I need a credit card to try it?
No, you can start without a credit card. Students with a school email get 40% off paid plans.
