Flashcards in Avendoo are digital flashcards used for memorizing and reviewing learning content. They facilitate individual knowledge acquisition through repetitive, self-paced learning.

Each flashcard consists of two sides: a front (e.g., technical term) and a back (e.g., definition of the technical term). Multiple flashcards can be grouped into a flashcard set that is systematically reviewed. Flashcards can contain content in text format, using the editor, or using design templates.
