Chinese Brain szerző: Chris

Chinese Brain turns everything you read and watch into Taiwan Mandarin practice.

HOVER ANY CHINESE WORD
• Traditional characters with Taiwan standard pinyin (教育部 readings), because tones are sometimes different from China's
• Meaning and breakdown: 臺北市 → 臺北 → 臺 · 北, then 市
• Two natural Taiwan-Mandarin example sentences, where the other words are ones you already know

ONE WORD LIST, THREE STATUSES
• 新 Fresh · 學 Learning · 熟 Known: press 1, 2 or 3
• Words will be shown in the same colors in the card, the subtitles, the transcript, your word list, and (optional) on every page
• Import your known-words list; export to AI what changed each week as a small TSV (if you regularly work with AI to learn Chinese)

YOUTUBE DUAL SUBTITLES
• Chinese + English lines over the video; every word is hoverable and clickable
• The video pauses while you read (optional)
• Transcript with a "learn first" list: the words that unlock the most of this video
• How much of the video you already know, as a percentage

OPTIONAL, WITH YOUR OWN KEYS
• Gemini: subtitles for videos without Chinese captions (Mandarin is transcribed; other languages are translated into Taiwan Mandarin), and new example sentences
• Azure: a Taiwan neural voice

Free. No account and no server of ours; your word list stays in your browser.
