How an AI quiz maker builds questions from your material

Quizzes are most useful when they come from the exact chapter, lecture or handout you will be tested on. A AI quiz maker reads your upload and writes questions that stick to its wording and emphasis, so the practice matches the exam more closely than a generic question bank.

Multiple-choice, true/false and short answer questions from one upload

Plus and Pro add exports for PDF, DOCX, QTI 2.1 and Moodle XML

Example immune system quiz questions

Which type of immunity do memory B and T cells provide?Adaptive immunity. Memory cells remember a previously encountered antigen, so they respond faster and more strongly on re-exposure.

True or false: antibodies are produced by red blood cells.False. Antibodies are produced by plasma cells, which develop from B lymphocytes.

Which white blood cells are usually the first responders to infection?Neutrophils. They are the most abundant white blood cells and reach sites of infection quickly to engulf pathogens.

What do helper T cells (CD4+) do during an adaptive immune response?They release cytokines that activate B cells and cytotoxic T cells, coordinating the response.

Why do vaccines lead to the formation of memory cells?Vaccines expose the immune system to an antigen safely, so memory B and T cells form and respond faster when the real pathogen appears.

Three question types

Multiple-choice, true/false and short answer questions, each with an explanation of why the correct answer is right.

Works from your own material

Upload PDF, DOCX, PPTX, plain text or notes, or a photo of a page that is read with text recognition.

Export when you need to

Plus exports to PDF and DOCX. Pro adds QTI 2.1 and Moodle XML for course platforms.

How it works

Upload your material

Add the file, slides or notes your course is built around.

Choose question types

Pick multiple-choice, true/false, short answer or a mix, and set how many you want.

Practice and review

Answer in the browser, read each explanation, and revisit the questions you missed.

Each question includes an explanation, which matters as much as the answer. When you miss a question about why antibodies cannot neutralize a virus inside a cell, the explanation shows the reasoning behind the correct option, so the mistake becomes something you learn from.

Mixing question types helps. Multiple-choice questions test recognition, true/false questions catch confusion between similar terms, and short answer questions make you retrieve the idea without cues. Use all three across a week rather than the same format every session.

Frequently asked questions

How many quiz questions should I practice for the immune system?

Start with 10 to 15 questions per chapter and mix multiple-choice with true/false. Include some short answer questions once you can recognize the terms, since those test recall without cues.

What is the best way to study with quiz questions on the immune system?

Answer each question before reading the explanation, then retry the ones you missed after a day or two. Spacing out the review makes the difference between innate and adaptive responses easier to remember.

Can I export my quiz?

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

Do I need a credit card to start?

No. You can start on the free plan with 3 generations per month and no credit card. Students with a school email get 40% off Plus.
