Create Smart Flashcards
from Any Material

Flashcards are effective because they leverage active recall—the process of retrieving information from memory rather than passively reviewing it. When you see a question and try to remember the answer before flipping the card, you're strengthening the neural pathways that store that information.

This is often called the testing effect: research shows that testing yourself on material leads to better retention than re-reading or highlighting. Even when you get answers wrong, the act of trying to recall strengthens memory.

Spaced repetition—reviewing cards at increasing intervals—amplifies this effect. Cramberry's mastery tracking helps you practice this by surfacing cards you struggle with more frequently while spacing out cards you've already mastered.
