Study list
Characters and words you saved, reviewed with spaced repetition. Everything stays in this browser — no account, nothing uploaded.
How spaced repetition works here
1. Save while you browse
Every character page and every HSK word row has a + Save button. Your list builds itself as you look things up.
2. Grade yourself honestly
After flipping a card, tell it how it felt. Each answer shows when you will see that card again, so nothing schedules in secret.
3. Missed cards come back
A card you forget returns after 10 minutes; one you know well stretches to 4 days and keeps growing. Accuracy beats volume.
Prefer a paper trail? HSK word lists and the character dictionary work without saving anything. Curious how much of it has stuck? See your progress .
