How to make Anki cards that actually work

Anki does not fail students. Bad cards do. The scheduling algorithm can only optimize review timing for the card you actually wrote, and a vague, overloaded, or poorly phrased card wastes every review it gets, no matter how well-timed it is.

Here is the process I wish someone had explained to me before I burned a semester on cards that looked fine and reviewed terribly.

1. One fact per card

This is the single biggest fix available to most Anki decks. If a card asks you to recall three things at once, a definition, an example, and an exception, you will start rating it "Good" the moment you remember two out of three. That quietly breaks the scheduling, because the algorithm thinks you know the card fully.

Split it. One card for the definition. One for the example. One for the exception. It feels like more work upfront, but each card reviews cleanly, and cleanly-reviewed cards are what make spaced repetition actually work.

2. Write the question so there is only one right answer

Avoid yes-or-no phrasing and vague prompts like "Tell me about mitochondria." Instead, ask something with a single, specific, checkable answer: "What is the primary function of the mitochondria in a eukaryotic cell?" You want to know immediately, without ambiguity, whether you got it right.

3. Use cloze deletions for things you'd naturally recall in context

Not everything fits a front-and-back format well. For processes, sequences, or sentences you would normally recall as a whole (like a formula or a step in a mechanism), a cloze deletion, hiding one word or phrase inside a full sentence, tests recall more naturally than an isolated question-and-answer pair.

4. Add an image or a mnemonic when the concept is spatial

Anatomy, diagrams, and anything involving relative position between parts are hard to encode as pure text. A single labeled image occlusion card will outperform ten text-based cards trying to describe the same structure. Reserve mnemonics for facts that resist visual representation, like ordered lists or arbitrary sequences.

5. Tag and organize by subtopic, not just by deck

A single "Biology" deck with 2,000 untagged cards makes targeted review impossible before a specific exam. Tag cards by chapter or subtopic so you can filter down to exactly what is being tested, especially useful in the final week before an exam when you need to drill weak areas, not the whole semester.

6. Trust the algorithm and answer honestly

Rate each card by how well you actually recalled it, not by how you wish you had. FSRS-5 adjusts future review intervals based on your ratings, and inflating them to feel good about your progress just pushes cards you do not actually know further out, right when you need them reviewed sooner.

Making cards faster

Every principle above is about card quality, not creation speed, and creation speed is still the real bottleneck for most students. If you are spending more time formatting cards than reviewing them, that ratio is backwards.

FORKSAI applies most of these same rules automatically: it splits concepts into atomic cards, phrases questions with a single clear answer, and schedules reviews with the same FSRS-5 algorithm, straight from a PDF, your notes, or a slide deck. You still control difficulty, question type, and card count, but the manual writing step disappears.

If you would rather stay in Anki and only remove the typing, the free text to flashcards tool converts pasted notes into cards in your browser and exports a file Anki can import, which keeps your existing deck and scheduler exactly as they are.

Where the cards come from is a design decision worth making deliberately rather than by accident. Some tools grow them out of the notes you write, using a syntax you apply as you go. Others generate them from material you already have. The two approaches suit different people for reasons that have little to do with card quality, and the difference is set out in the guide to keeping flashcards and notes in one app.
