Anki flashcards explained, and how to make your own from notes
Anki flashcards are a proven way to memorize facts over time. Upload your PDFs, slides, notes or photos and get a deck built from your own material.
How Anki flashcards work
Most people first meet Anki flashcards when a teacher or classmate recommends them for memorizing facts. Each card shows a question or term on the front and the answer on the back, and the app decides when to show it again.
- Each card tests one fact or idea.
- Review sessions are short and repeated over days or weeks.
- Clear wording on the front and a brief answer on the back makes recall faster.
- Cards can include images, which helps with diagrams, maps and labeled parts.
Spaced repetition
Cards you miss come back sooner, and cards you know wait longer, so review time goes where it counts.
Prompt and answer
Each card has a question or term on one side and the answer on the other, which keeps every review to one idea.

Review on a schedule
Study in the browser on the free plan, or export to Anki on Plus.
The scheduling is the key idea. Anki uses spaced repetition: each time you answer, the app adjusts when that card returns. Cards you get right come back later, and cards you miss come back sooner, so you spend less time on facts you already know.
DeckOwl can build a deck like this from your own notes, so you can start from your course material instead of typing every card by hand.

Frequently asked questions
What is the difference between Anki flashcards and paper index cards?
Anki schedules each card based on how well you recalled it. Index cards give you no schedule, so you have to decide yourself when to review each one.
How many flashcards should I make for one topic?
Make one card per fact you need to recall, and keep each chapter to a manageable set. If a card takes several seconds to answer or holds more than one fact, split it into two.
Can I export DeckOwl cards to Anki?
Yes, export to Anki is a Plus feature at $39/year or $7.99/month. The free plan lets you study flashcards in the browser without exports.
Do I need a credit card to try it?
No. You can start on the free plan, which includes 3 generations per month, without adding a credit card.
