How a quiz maker fits into studying from your own material

Writing practice questions by hand takes longer than the study session they are meant to support. This quiz maker reads your own material and drafts questions from it, so the quiz matches what your instructor actually covered.

Questions are built from the files you upload, not from generic templates.
Each question comes with an explanation of why the answer is correct.
Free plan includes 3 generations per month and browser study.
Plus and Pro add exports for PDF, DOCX, Anki and CSV, with QTI and Moodle XML on Pro.

Multiple choice, true/false and short answer

Pick the question format that fits the material. Each question includes an explanation of the correct answer.

Reads PDFs, slides, DOCX and photos

Text recognition handles photos of pages, so printed handouts and textbook scans work as well as typed notes.

Study in the browser or export

The free plan lets you study in the browser. Paid plans add PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML for course systems.

How it works

Upload your material

Add a PDF, DOCX, PPTX, plain-text notes or photos of pages.

Choose the question types

Select multiple choice, true/false or short answer, then generate the quiz.

Review and practice

Check each question and explanation, remove anything weak, then work through the quiz.

Drafts are a starting point, not a final answer. Read each question and its explanation before you rely on it, and edit or delete anything that is unclear or outside the scope of your course.

Testing yourself on recall tends to show gaps faster than rereading. Generate a fresh quiz from each new chapter or lecture so your practice keeps pace with the course.

Frequently asked questions

How many practice questions should I make before an exam?

Start with a set that covers one chapter or lecture so you can review the explanations while the material is fresh. Repeat with later sections, and retake earlier quizzes to check what you still remember.

What makes a good study question for a quiz?

A good question tests one idea and has a single clearly correct answer. Explanations matter as much as the answer, because they show the reasoning you need to apply on new problems.

Can I export my quiz to Moodle or PDF?

PDF and DOCX export are available on the Plus plan. QTI 2.1 and Moodle XML export are available on the Pro plan.

Do I need a credit card to try it?
