Spaced Repetition Without Making Decks

Spaced repetition has a reputation problem, and it's not the algorithm's fault. The algorithm — show me a word right before I'd forget it — is one of the most reliably effective techniques in learning research. The problem is the tax you pay before the algorithm ever runs: making the cards.

The card-making tax

Take a realistic case: you're reading a novel in Italian and meeting twenty unfamiliar words a week. To get those into a classic flashcard app you need to, per word:

1. Stop reading.
2. Look the word up somewhere.
3. Copy the word, the meaning, and ideally the sentence you found it in.
4. Format a card and file it in a deck.

Call it ninety seconds per word when you're disciplined. That's half an hour a week of clerical work — on top of the reviews, which are the part that actually teaches you anything. And the failure mode isn't that you do this slowly. It's that after three weeks you stop doing it at all, and the whole system dies with the deck.

This is the quiet reason most abandoned spaced-repetition setups were abandoned. Not the reviewing. The making.

What people try instead

Shared decks. Download a "top 5,000 Italian words" deck and skip card-making entirely. The cost: the deck's words aren't your words. You review cavallo because it's frequency rank 800, not because you met it yesterday — and you don't review the word you actually got stuck on in chapter three, because the deck's author never read your book. Frequency decks are decent for absolute beginners; past that, the mismatch grows every week.

Batch capture. Highlight words while reading, then make cards in a weekly session. Better than interrupting your reading — but you've created a backlog, and backlogs are where good intentions go to die. The sentence context is also gone by Sunday; you're left with a bare word and a dictionary.

Export pipelines. Kindle's vocabulary builder, browser pop-up dictionaries like Yomitan, and various scripts can export your lookups into Anki. When these fit your exact setup — your device, your language, your e-book format — they genuinely work. They're also fiddly to assemble and tend to break at the seams. We compare them properly in Anki for reading?

The other option: cards that create themselves

The card-making tax exists because the dictionary and the flashcard app are two different tools. Merge them and the tax disappears: if the app that shows you a word's meaning is the same app that schedules your reviews, then looking a word up and making its card become one action.

That's the premise Word Holder is built on. You read — a built-in passage, an imported article, anything — and when you look up a word, the card already exists: the word, its meaning, an example sentence, captured at the moment you met it. It enters an SM-2 review schedule — the same algorithm family that powers Anki — and the next day the app tells you how many words are due. The review itself is a fill-in-the-blank sentence, so you're recalling the word in context, not recognizing a flashcard you've seen before.

No deck, no note types, no settings. The spaced repetition is still there — it's just nobody's hobby anymore.

Is zero-effort capture always better?

Honestly: no. Making a card by hand has one real benefit — the act of writing a definition in your own words is itself a memory aid (the "generation effect"). If you have the discipline to hand-craft every card and you enjoy it, Anki rewards that work, and our comparison of Anki alternatives will tell you to stay right where you are.

The question is what happens when discipline meets a 400-page novel. A slightly-less-handmade card you actually review beats a perfect card you never made. If your deck-building habit keeps collapsing under real reading, stop blaming your discipline and remove the tax instead.
