Turn what you watch into what you remember. Every drill here runs entirely in your browser — nothing you type is sent anywhere. Pick a mode to get started.
Spaced-repetition review of the words from what you watch. See a character, type the pinyin, and cards you miss come back sooner.
Type-what-you-hear drills. Play a short line, type the pinyin you hear, and check yourself instantly.
Character and pinyin writing practice. Switch between typing the characters for a word and typing its pinyin.
Decks are built from the vocabulary in the clips you watch, so review reinforces real context.
Every drill is a keyboard drill: type the pinyin or the characters and get an instant check.
Cards you find hard come back sooner; cards you know drift further apart. Progress is saved locally.
