How a ChatGPT-style quiz generator fits into studying

Writing ten practice questions from a 30-page chapter usually takes longer than reading the chapter itself. DeckOwl works as a ChatGPT quiz generator for your own material, so the questions come from the pages you already have rather than from a general chat.

Questions are based on the files you upload, not on a general guess about the topic.
Each multiple-choice, true/false or short-answer question includes an explanation.
The free plan includes 3 generations per month and browser study.
Paid plans add unlimited generations and export options for your materials.

Example questions about how ChatGPT works

What kind of model is ChatGPT?A large language model that predicts likely next words in text, so it can produce fluent answers that are not always factually correct.

True or false: ChatGPT always checks live web sources before answering.False, because its answers rely mainly on training data unless a browsing tool is turned on, so recent events may be missing.

Why should you verify quiz answers written by an AI from your notes?Language models can state incorrect facts with confidence, so each answer needs checking against the source material.

What details make a prompt to ChatGPT more useful for quiz writing?The source text, the number of questions, the question types and the required format, because specifying them reduces guesswork about the output.

What is an AI hallucination?A confident-sounding output that is not supported by the facts or the source provided, which is why generated quizzes need review.

Generate the full set

Questions from your own material

Quizzes are built from the PDFs, slides, DOCX files, text or photos of pages you upload, so the questions match your course rather than generic topics.

Explanations for every answer

Each question comes with a short explanation, so a wrong answer becomes a lesson instead of a dead end.

Export when you need it

Study in the browser on the free plan. Paid plans export to PDF, DOCX and Anki, and Pro adds QTI 2.1 and Moodle XML for course platforms.

How it works

Upload your material

Add a PDF, DOCX, PPTX, text file or photo of a page. Text recognition reads images.

Choose the question types

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

Study and review

Take the quiz in your browser, read the explanations, and export the set if your plan includes it.

The quality of any generated quiz depends on the source. Upload complete notes instead of a short summary, check that the explanations point back to the right section, and remove questions that depend on material your course never covered.

A quiz is most useful when you take it more than once. Retake missed questions after a day or two, and use the explanations to decide what to reread.
