Why an Anki deck may show fewer cards than you added

When an Anki deck not showing all cards problem appears, the cards are usually still in the collection. Anki limits how many new cards and reviews appear each day, hides suspended and buried cards, and only shows cards that are due. Check the deck options, your search filter and whether any subdecks are collapsed before you assume anything was deleted.

Check the daily new card limit in your deck options and raise it if it is set low.
Look for suspended or buried cards in the browser and unsuspend the ones you need.
Clear any search filter or custom study session that is hiding part of the deck.
Rebuild the deck from your source notes when the original import was incomplete.

Frequently asked questions

How many flashcards should I make per topic?

Keep each card to one fact so you can recall it on its own, and split long lists into several cards. A cell biology unit often needs a few dozen cards, but clarity matters more than the total count.

How do I study a large deck without getting overwhelmed?

Set a fixed number of new cards to learn each day and let spaced repetition bring back the ones you miss. Missing a day is fine as long as you return to the schedule.

Can DeckOwl export flashcards to Anki?

Yes, Anki export is included on the Plus plan at $39/year or $7.99/month, along with PDF, DOCX and CSV export. The free plan lets you study in the browser without exports.

Do I need a credit card to try DeckOwl?

No. You can start on the free plan with 3 generations per month and no credit card.
