How an AI quiz generator helps with programming courses

Programming exams reward quick recall of syntax, return values and edge cases, and that is where an AI quiz generator for code earns its keep: upload your lecture slides or notes and it drafts questions you can answer before the test.

Generate quizzes from lecture slides, PDFs and handwritten notes photographed as images.
Practice multiple-choice, true/false and short-answer questions, each with an explanation.
Use the free plan to study in the browser with 3 generations per month.
Export to Moodle XML or QTI 2.1 on the Pro plan for course quizzes.

Example programming practice questions

In Python, what does len('stack') return?5. len() counts the characters in the string, and 'stack' has five letters.

What is the time complexity of binary search on a sorted array?O(log n). Each comparison halves the remaining search range.

True or false: in Python, lists are immutable.False. Lists are mutable, so their items can change in place, while tuples are the immutable sequence type.

What is a closure in JavaScript?A function that keeps references to variables from the scope where it was defined, even after that outer function has returned.

Why should SQL queries use parameterized statements?They keep user input separate from the query text, which prevents SQL injection.

Generate the full set

Questions from your own material

Quizzes are built from the slides, PDFs and notes you upload, so the practice matches what your instructor actually covered.

Explanations for every answer

Each question comes with an explanation, so a wrong answer about syntax or behavior teaches you why the correct option works.

Photos and scans read as text

Photographed pages from a whiteboard or printed handout are read with text recognition, so they can feed the quiz too.

How it works

Upload your course material

Add a PDF, DOCX, PPTX, plain text file or a photo of your notes.

Choose the question types

Pick multiple-choice, true/false or short answer questions, then generate the quiz.

Answer, check and repeat

Work through the questions, read the explanations and retake the weak topics until the answers are consistent.

Mix question types to match how your course is graded. Multiple-choice questions check whether you can spot the right library call or data structure, true/false questions catch common misconceptions, and short-answer questions force you to explain what a function does in your own words.

Treat the output as a study draft rather than a source of truth. Check each answer against your course material, especially for code examples, because the tool reads your text but does not run the code it contains.

Frequently asked questions

How many quiz questions should I practice for a programming exam?

Aim for enough questions to cover every lecture topic at least twice, rather than a fixed number. Track which topics you miss and generate a new quiz focused on those.

Should I quiz myself on code by reading it or writing it out?

Writing out answers and predicting what a snippet prints works better than rereading, because it forces active recall. Check your prediction against the explanation and then test the code yourself.

Does DeckOwl run the code in my notes?

No. DeckOwl reads the text in your files and writes questions about it, but it does not execute code, so verify any output-based question by running the snippet yourself.

Can I export code quizzes to Moodle?

Yes, Moodle XML and QTI 2.1 export are included in the Pro plan at $14.99 per month. The free plan lets you study in the browser but does not include exports.
