Waku — Chinese immersion for YouTube

Dual subtitles, tap any word to look it up, and build flashcards while you watch Chinese videos on YouTube.

Waku turns YouTube into a Chinese class made of things you actually want to watch. POINT AT A WORD The video stops and the meaning appears — in your own language, not just English. Move away and it plays on. You never have to click to understand something. CLICK ONLY TO DECIDE Clicking opens the word's card: pronunciation, the characters it is built from, where you have met it before, and two buttons — I know this, or Save word. REVIEW WHAT YOU SAVED Saved words become flashcards, each shown inside the sentence you met it in, with a link back to that moment in the video. Spaced repetition decides when you see them again. FIND VIDEOS YOU CAN LEARN FROM Videos with Chinese subtitles glow and carry a 字 中文 tag, everywhere on YouTube — search, home, sidebar. Everything else stays dark, so you never open a dead end. ALSO - Dual subtitles: Chinese with pinyin above, a translation below - Tones colour-coded, so you see the tone before you hear it - Simplified and traditional, whichever the video uses - A side-by-side transcript you can read and jump around in - A reading view for after you watch - Loop a line to shadow the speaker - See how much of a video you already know before you start it - Export to Anki - Seven themes - A Progress page showing every day you have learned - Ten themes, three of which open as your streak grows WAKU SPEAKS ARABIC TOO Not just the meanings — the whole interface, right to left, if that is the language you think in. NO ACCOUNT, NO SIGN-UP Your saved words stay on your computer. There is no server and nothing to log in to. The dictionary is CC-CEDICT, used under CC BY-SA 4.0.
