Beyond front-and-back: the flashcards that actually teach
Cloze deletions, image occlusion, smart multiple-choice, and scenario cards — the five card types Lumo generates from your notes, and when each one beats a plain Q&A.

A plain question-and-answer card is a good tool — for some facts. But not every idea is a question with a single word behind it. Force everything into front-and-back and you get cards that are either trivially easy or hopelessly vague. Lumo generates five card types from your source and picks the right one for each idea.
1. Short-recall Front-Back
The classic, done well. The key is a short front — a term or a crisp question, not a paragraph. "What does ATP stand for?" is a recall cue. A half-page front is just re-reading with extra steps. Lumo keeps fronts tight so each card tests one retrieval.
2. Cloze deletion
Cloze cards blank out a key term inside a real sentence — for example,
The powerhouse of the cell is the {{c1::mitochondrion}}. They're ideal for
definitions and processes, because you recall the missing piece in context
rather than in isolation. Context is exactly what makes the memory stick.
3. Image occlusion
For anything spatial — anatomy diagrams, labelled cycles, maps — image occlusion hides a label on a picture and asks you to name it. It's the single most effective card type for visual material, and it's notoriously tedious to make by hand. Lumo builds them for you.
4. Smart multiple-choice
A multiple-choice card is only as good as its wrong answers. Throwaway distractors ("none of the above") teach nothing. Lumo generates plausible, misconception-based distractors — the wrong answers a student who half-learned the topic would actually pick — so getting it right means you genuinely discriminated, not guessed.
5. Scenario / application
The hardest and most valuable type: a short situation that asks you to apply a concept, not just restate it. "A patient's blood pH drops — which system responds first?" These are the cards that move you from recognition to understanding, and they're what exam questions are actually made of.
The mix is the point
A strong deck isn't 40 identical Q&A cards. It's a blend — cloze for definitions, occlusion for diagrams, MCQ for discrimination, scenario for application — matched to the material. Lumo assembles that mix automatically, and a critic agent reviews the deck before you see it, flagging weak, duplicate, or low-value cards so they never reach your review session.
