Illustrative question
In this experiment, the researcher changes the amount of light and measures plant growth. What is the dependent variable?
- Amount of light
- Measured plant growth
- The label on the plant pot

Turn a PDF into a quiz and find out which parts you can explain with the document closed. Start with one readable chapter, answer the questions, then check the corrections and any missing topics against the original.
An AI quiz generator should keep each question tied to evidence in your document. Good distractors are plausible but wrong for a clear reason, and feedback should help you identify the concept behind a mistake.
Use a short first quiz to diagnose gaps, correct them from the source, then generate or select another round that tests the weak relationships.
Start with one readable chapter or handout rather than an entire mixed course pack. Answer each generated question before reopening the file, then compare the explanation with the original passage. If a condition, unit, exception or sequence was simplified, the PDF remains the authority. Correct the study note and repeat the concept in another game.
Selectable text, descriptive headings and complete sentences give the generator clear evidence. Image-only scans, dense tables, handwritten annotations and formulas need closer checking. Split long documents by topic so the questions cover one coherent learning goal. Memorizite accepts PDF, TXT and Markdown files up to 10 MB.
A paragraph about activation energy, temperature and denaturation can support several different checks: identify what an enzyme changes, distinguish an optimum from permanent damage, and connect a temperature change with its consequence. These questions test relationships in the paragraph rather than unrelated biology trivia.

A good quiz question needs enough context to have one defensible answer. Consider notes that say: “In a controlled experiment, the independent variable is changed by the researcher, while the dependent variable is measured.” A useful question asks which variable is measured. A weaker question asks “Which variable changes?” because both may change for different reasons.
In this experiment, the researcher changes the amount of light and measures plant growth. What is the dependent variable?
The dependent variable is the measured outcome. Light is the independent variable in this example. Naming both makes the question more useful than simply memorizing a letter in the answer list.
This hand-written example shows what to look for when reviewing AI output.
For a self-test covering several topics, see the practice test workflow. For short definition practice alongside quizzes, use flashcards from your notes. Your original material remains the reference when an explanation needs checking.
Every format below is produced by the app today from a single upload — no separate tools or modes to configure:
Each answer feeds mastery tracking per concept: the app records what you got right and wrong, shows memorization and understanding scores per document, and brings weak concepts back automatically. Over days of quizzes, the record of your answers becomes an honest map of what you know — far more reliable than how confident a reread feels.
Say you upload a biology chapter on cells. A few seconds later you could be answering something like this:
That is the whole idea: real questions, built from your material, with feedback on every single answer.
Because the questions come from whatever you upload, the same generator serves very different goals: students turning lecture slides into a pre-exam drill, teachers building a quick starter quiz from tonight's handout (see Memorizite for teachers), and professionals working through certification material one chapter at a time. Pair it with the exam prep app when a test date is approaching, or warm up with our study games first.
Turn a PDF into a quiz in minutes: upload a chapter or handout and this PDF to quiz flow builds questions from the key ideas. As a PDF to quiz generator it handles anything readable, and as an AI quiz maker from PDF files it explains every answer. Prefer typing? The notes to quiz path takes whatever you write, where the question generator from text handles it — while the question generator from PDF and quiz generator from PDF paths cover uploads, so you can make a quiz game from any material you study.
