Subsgen Interactive Subti

SubsGen — Interactive Subtitles for Language Learners | YouTube & Bilibili

Turn any YouTube or Bilibili video into an interactive language lesson. Hover words for instant translations, click to hear pronunciation, and follow along with color-coded vocabulary highlighting — directly inside subtitles, comments, and video descriptions.

Built for any language with captions:
Chinese, Russian, Spanish, English, Portuguese, French, German, Vietnamese, Thai, Korean, Indonesian, and more.

The strongest experience is for Chinese learning, with full pinyin support, HSK color coding, traditional/simplified switching, and advanced word segmentation — but any subtitled video becomes study material.
