A simple, transparent review system for the words and ideas you saved. It lives entirely in this browser.
How it works. Each card is shown again on a schedule that grows with each correct answer. Four buttons: Again (starts over), Hard, Good, Easy. This is a simple SM-2-style schedule — not scientific perfection and not “AI personalisation”.
No cards due right now. Add cards from any lesson (look for the “＋ Review” buttons), or load the starter deck.
Cards are saved on this device only — no account, no upload, no sync.
