How the AI quiz generator works with your material

Teachers and students who already use ChatGPT often want quizzes built from their own readings rather than from a blank prompt. DeckOwl's AI quiz generator reads your PDF, DOCX, PPTX, plain text or photographed pages and writes questions only from that content.

Questions are drawn from the files you upload, not from general web knowledge.
Multiple-choice, true/false and short answer formats are available.
Explanations show the reasoning behind each correct answer.
Quizzes can be taken in the browser on the free plan.

Example quiz questions about how ChatGPT works

What is a large language model?A neural network trained on very large text collections to predict likely next words. This is why answers can sound fluent and still be wrong.

True or false: ChatGPT checks every answer against a live fact database.False. Answers are generated from patterns learned in training, so facts and sources still need checking.

What is a token in a language model?A chunk of text, often a word or part of a word, that the model processes as one unit. Token limits control how much text fits into one prompt.

What is prompt engineering?Writing instructions that shape a model's output, such as stating the role, task and format. Clear prompts usually produce more useful results.

What is a hallucination in AI output?A confident answer that is not supported by the source material or by fact. It is why generated quiz answers should be checked against your notes.
