Flashcards drill your own material rather than someone else's summary of the topic. They are part of the Pro and Lifetime plans.
Creating a deck
Open the note you want to study. On desktop, type / and choose Flashcards. On mobile, open the apps group on the toolbar above the keyboard and choose Flashcards. A card appears in the note, and generating creates ten study cards from the note content.
Reviewing
Open the flashcards from the card in the note. Click or tap a card to flip it, and step through the deck with the arrows. The deck stays attached to the note, so the day before the exam it is exactly where the material is.
Regenerating
The deck mirrors the note at the moment you generate. If the note has grown since, generate again for a fresh deck.
Getting better cards
The cards come from the note, so a note with clear headings and complete sentences produces a better deck than a wall of abbreviations. If a card comes out muddy, the fix is usually one clearer paragraph in the note.
The other study tools
The same notes can become a quiz or a mind map, each built for a different kind of studying.
