Practice cards

Make your own cards and test yourself. Each one comes back just before you would forget it.

Draft cards from my notes (AI)

Paste your notes and an AI drafts questions and answers from them. Your notes are sent to Cloudflare Workers AI to do this; we don't store them. Don't paste anything private. The AI can get things wrong, so check each card before you add it.

    How to use it

    1. Write a question and its answer. Callouts, combos, keybinds, build orders, or words for school.
    2. Press Start. Answer in your head (or out loud) before you look.
    3. Tap "Got it" only if you really knew it. "Not yet" brings the card back later in the same session.
    4. Come back on another day. The tool only asks the cards that are due.

    Each card sits in one of five boxes. Get it right first try and it moves up a box and waits longer: 1, 2, 4, 8, then 16 days. Miss it and it goes back to box 1. We chose these gaps as a simple start; no study says they are the best ones.

    Why it works

    A large review of study methods rated two as the most useful, for learners of many ages: testing yourself, and spreading practice out over time (Dunlosky et al., 2013 (opens in a new tab)). Cards do both.

    In one study, students who tested themselves remembered much more a few days or a week later than students who re-read the same text, even though re-reading made people feel more confident. Re-reading only won on a test five minutes later (Roediger & Karpicke, 2006 (opens in a new tab)).

    A review of 317 experiments found that spacing helps, and that the longer you need to remember something, the longer the best gap between sessions (Cepeda et al., 2006 (opens in a new tab)). That's why the gaps grow.

    This helps you remember what's on your cards. It isn't brain training, and it won't make your memory better in general.

    When to use it

    • Learning a new map, agent, champion or character.
    • Before a test or exam: a few minutes a day beats one long night.
    • In a queue or between matches: one short session.
