The short answer

The fastest way to build a quiz generator: use an LLM to create questions from your source material (lecture notes, textbook chapters, articles), store them in Anki (29,543 stars) for spaced repetition, and auto-grade with the same model. Everything is free and self-hosted.

Pattern 1 - Generate questions from any text

import openai
text = open("chapter3.txt").read()
resp = openai.chat.completions.create(
    model="gpt-4o-mini",
    messages=[{"role": "user", "content":
        "Create 10 multiple-choice questions from this text, 4 options each, "
        "with correct answers. Return JSON. " + text[:8000]}])
print(resp.choices[0].message.content)

Pattern 2 - Cloze deletion for memorization

Ask for fill-in-the-blank cards ("The capital of France is ___") - these are the most effective for spaced repetition in Anki.

Pattern 3 - Auto-grading

resp = openai.chat.completions.create(
    model="gpt-4o-mini",
    messages=[{"role": "user", "content":
        f"Grade this answer to '{question}' out of 10 with one-line feedback: {answer}"}])

Pattern 4 - Difficulty calibration

Have the model tag each question 1-5 by difficulty, then schedule harder questions less frequently - Anki handles the scheduling.

Pattern 5 - Import to Anki

Export questions as CSV (Front,Back,Tags) and import into Anki, or use AnkiConnect for scripted sync.

Real numbers

• Generating 100 questions from a textbook chapter costs ~$0.05-0.2 with a mini-class model.
• Anki's spaced repetition lifts 30-day retention from ~30% (cramming) to 80%+.
• The full stack runs on a laptop - no cloud accounts needed.

FAQ

Q: Are the questions any good? A: Mini-class models generate good MCQs from clear source text; review and edit the first batch, then calibrate your prompt.

Q: Can students use it too? A: Yes - feed it your notes, generate self-quizzes, and Anki handles review scheduling.

Q: What about math questions? A: LLMs handle basic arithmetic and algebra; for LaTeX-heavy questions, ask for LaTeX output and render with MathJax in Anki.
