Free online flash cards

Flash cards work because they force retrieval: you see the front, you pull the answer from memory, and you find out immediately whether it was really there. Every study deck here runs on that loop — flip the card, grade yourself honestly, and anything you mark "still learning" re-queues automatically before the session ends, so your weak spots get the most practice without you managing anything.

The decks cover the classics people actually search for: the 2–12 multiplication tables, US state capitals, world capitals, the first 36 elements of the periodic table, every US president in order, the essentials of the human body, and 100-word starter vocabularies for Spanish and French. Each session ends with a report — cards studied, percent known on the first try, your misses, and your best score over time, stored in your browser.

Nothing here needs an account or an app. Open a deck, flip the first card, and you're studying. If you want a deck we don't have, the deck builder lets you write your own and play it with the same player.
