Why LLM-Generated Flashcards Are Usually Bad, and How to Screen Them

1Key Takeaways

• I've watched a lot of teams bolt an LLM onto a document and call the output flashcards.
• It demos beautifully and it teaches badly.
• The generated cards look plausible — grammatical, on-topic, correctly formatted — and they fall apart the moment a real learner tries to review them six weeks later.
• The core problem is that "summarize this into Q&A pairs" optimizes for a different objective than "produce items that are cheap to recall and hard to fake." Those two things diverge fast.
