BiliSub per cxx-u

BiliSub adds real-time multi-language subtitles to Bilibili videos. It automatically detects and enables available AI-generated Chinese subtitles, with a fallback to AI-generated English subtitles when Chinese subtitles are unavailable.

Subtitles are translated in real time using Google Translate and displayed as dual subtitles or translation-only subtitles. Users can choose from 100+ supported languages, toggle automatic translation, and adjust subtitle font size.

BiliSub requires an available AI-generated subtitle track from Bilibili. Videos without a supported AI subtitle track cannot currently be translated.
