Chénjìn Mandarin Tools

Learn Mandarin from the videos you watch: interactive subtitles with pinyin, dictionary lookups, sentence mining, and SRS review.

Turn the Chinese content you already watch into your personal Mandarin curriculum. Chénjìn connects the videos and articles you love to your chenjinmandarin.com account, so every subtitle line and every sentence you read can become study material. WATCH AND LEARN • Live subtitle browser for Chinese-subtitled video on all major streaming platforms (see the full list of supported sites on our website) • Every subtitle line displayed with pinyin, synced to the video, with auto-pause and auto-resume so you can study a line before the next one plays • Tap any word for a full dictionary entry: definitions, pinyin, audio, example sentences, radicals, and related words • Filter subtitles by what you know: see only lines with exactly one new word (i+1) — the sweet spot for learning • Tracks which words you know, and shows how much of a video you can already understand before you start MINE SENTENCES ANYWHERE • Right-click Chinese text on supported social, forum, and reference sites to look it up or save it • One click saves a sentence — with its translation, pinyin, and audio — to your review deck REVIEW AND REMEMBER • Built-in spaced-repetition review (SRS), right in the popup • Export flashcards to your own study apps, or use natural text-to-speech in mainland and Taiwan voices Chénjìn is built for comprehensible-input learners: instead of textbook sentences, you learn from real shows, real creators, and real conversations — at exactly your level. Requires a chenjinmandarin.com account. Some features depend on your subscription plan. The extension only runs on supported sites and only sends the text you look up or save to your own account — see our privacy policy for details.
