What are flashcards and how to study with them

A flashcard is a card with two sides: a question on the front and the answer on the back. You look at the question, try to recall the answer, and only then flip the card to check yourself.

Why flashcards work

The power of flashcards is in the recall attempt itself. This is an application of the testing effect: long-term memory gets stronger when part of your study time goes into pulling information out of your head instead of reading it.

In the experiments of Roediger and Karpicke, students who quizzed themselves remembered noticeably more a week later than those who spent the same time rereading the text. Rereading creates a feeling of familiarity, while recall creates the knowledge itself.

There is one more benefit: honest feedback. When you flip the card, you immediately see what you know and what you do not.

What Revomia cards are like

A card in Revomia also has two sides and flips during study. Both sides are rich text: you can make lists or highlight the key part, just like in regular notes.

You can listen to card sides instead of only reading them. For language topics the service generates audio with pronunciation, for other topics your browser reads the text aloud.

Cards live in topics. You fill your own topics yourself, and you can subscribe to system topics — a shared catalog of ready-made sets.

How to create cards

The simplest way is by hand: a question on one side, the answer on the other. Keep the card short: one question, one answer.

The second way is to hand the work to AI: give it your own text and it will build cards from it that you can review and edit. In language topics AI also accepts a photo of your notes.

Flashcards plus spaced repetition

Flashcards have long been combined with scheduled reviews — from the paper Leitner system to modern apps. In Revomia the schedule is driven by the topic rule: after each review the card moves to the next pause in days, and you work through today's deck on the study page.
