Create front-back flashcards for efficient studying. Multiple decks, shuffle mode, and self-testing. Data stored locally.
Flashcards use active recall - you see a question (front) and try to remember the answer (back) before flipping. This is more effective than passive reading. Combined with spaced repetition, it dramatically improves long-term memory.
Data is stored in localStorage. It persists across sessions but clearing browser cache will delete all cards. Back up important cards periodically.
Tips: 1) Split cards into small decks (≤30 per deck); 2) Study 1-2 decks daily; 3) Try to recall before flipping; 4) Mark difficult cards for review; 5) Review previously learned cards regularly.
Currently data is stored in browser localStorage. You can view and export data via browser dev tools (F12 → Application → Local Storage).
