What is a flashcard and why does it work for studying?
A flashcard is a two-sided learning card with a prompt (term or question) on one side and the answer or definition on the other. They work because they leverage active recall — the act of retrieving information from memory — which is far more effective at building long-term retention than passively re-reading notes or a textbook.
What is spaced repetition and how does it relate to flashcards?
Spaced repetition is a study technique where you review information at gradually increasing intervals. Cards you struggle with are shown more frequently, while well-known cards are spaced further apart. Combined with flashcards, this produces dramatic improvements in long-term retention with less total study time than massed practice.
How do I import my own flashcards using CSV?
In the Create tab, click 'Import CSV' and paste your content. Each line should follow the format: term,definition. For example: Photosynthesis,The process by which plants convert light into glucose. You can import as many cards as you like in one go, and they are added to your existing deck.
Are my flashcards saved between sessions?
Yes. Your entire deck — including the deck name and all cards — is saved to your browser's localStorage automatically after every change. As long as you use the same browser on the same device, your cards will be there next time you visit.
What is the difference between 'Know it' and 'Review again'?
'Know it' (green checkmark) means you recalled the answer confidently. 'Review again' (red cross) means you hesitated or got it wrong. At the end of a session, the tool shows you your score and lists all cards marked for review so you know exactly where to focus next.
Can I use keyboard shortcuts while studying?
Yes. Press the Spacebar to flip the current card. Use the Arrow Left and Arrow Right keys to navigate to the previous or next card without needing to use the mouse.
