The short answer

The AI flashcard workflow: extract text from your study material (PyMuPDF, 10,400 stars, for PDFs), ask an LLM to generate cloze-deletion cards, import them into Anki (29,543 stars) - and Anki's spaced repetition handles the rest. Free, offline-capable, and you own the deck.

The generator

import fitz, openai, json

doc = fitz.open("chapter4.pdf")
text = "".join(p.get_text() for p in doc)[:20000]

resp = openai.chat.completions.create(
    model="gpt-4o-mini",
    messages=[{"role": "user", "content":
        "From this text, create 15 cloze-deletion cards. Format: "
        "Front (sentence with {{c1::key term}}), Back (explanation). "
        "Return JSON list. " + text}])

cards = json.loads(resp.choices[0].message.content)
# [{"front": "...{{c1::mitochondria}}...", "back": "..."}]
