LanguageHack: Learn Chinese on YouTube

Tap any word in Chinese YouTube subtitles for pinyin and meaning. Works offline; save words to spaced repetition with an account.

LanguageHack turns Chinese subtitles on YouTube into a tap-to-learn dictionary. Watch anything with Chinese subtitles — vlogs, lessons, dramas. Tap any word to see its pinyin, meaning and HSK level, then save it to your spaced-repetition deck with one tap. WHAT IT DOES • Clickable subtitles — every word in the Chinese caption becomes tappable • Instant pinyin + English meaning + HSK level, fully offline (bundled dictionary — the full New-HSK 1–9 set, ~11,500 entries) • Works even when the subtitles are part of the video itself (experimental): many Chinese videos have the words printed right onto the picture, with no caption track you can click. LanguageHack still recognizes those characters straight from the video image — something subtitle-based tools can't do • One-tap save to your LanguageHack spaced-repetition account (optional) • Traditional-script aware: 學/学, 什麼/什么 resolve to the same entry • Two overlay themes: Glass (transparent) and Warm (LanguageHack) PRIVATE BY DESIGN • Lookups work offline — no account required • When it reads words off the video image, that happens on your device — the video frames never leave your browser • No ads, no analytics, no data sale HOW TO USE 1. Open a YouTube video with Chinese subtitles — the overlay appears automatically. If the Chinese is printed onto the video (no caption track to click), switch on "Read on-screen subtitles" in the popup. 2. Tap a word to see pinyin and meaning. 3. Connect your LanguageHack account to save words, then review them daily at languagehack.online. NOTES • Dictionary covers the full New-HSK 1–9 vocabulary (~11,500 words) • Reading subtitles off the video image is experimental and uses more power while it's switched on • LanguageHack is an independent project, not affiliated with or endorsed by YouTube or Google
