Bililingo – Learn Chinese with Bilibili Subtitles

Learn Mandarin from captions while watching Bilibili videos.

Bililingo turns Bilibili subtitles into interactive Mandarin learning captions. It segments Chinese subtitle lines into words, displays pinyin above each word, and provides concise English definitions when you click a word. Features: • Chinese word segmentation • Pinyin displayed above words • Word-level English definitions from CC-CEDICT • Adjustable caption size and background opacity • Optional pause when inspecting a word • Local processing with no caption uploads How to use: 1. Open a Bilibili video that provides native subtitles. 2. Enable the video's subtitles. 3. Enable Bililingo. 4. Click any word in the learning captions to see its definition. Bililingo provides word-level definitions rather than full-sentence translation. Subtitle processing stays on your device. The extension does not upload captions, use analytics, or display advertisements. Settings are stored locally in Chrome. Bililingo is an independent, open-source project and is not affiliated with or endorsed by Bilibili.
