bilibili-digest
A browser extension that transforms Bilibili videos into structured learning resources using AI.
About bilibili-digest
bilibili-digest is a Chrome and Edge browser extension designed to enhance language learning and knowledge retention from Bilibili video content. It adds a sidebar to Bilibili’s web player interface, enabling users to read subtitles, view bilingual translations, generate AI-powered chapter overviews, get instant explanations for selected words, and create time-stamped notes.
The extension draws architectural inspiration and prompt engineering foundations from the youtube-digest project (MIT licensed), adapting it specifically for Bilibili’s platform and Chinese-language context. It targets learners who consume educational or technical content on Bilibili and want deeper engagement with video material.
It operates entirely client-side during browsing — no backend or account required — and integrates directly into the Bilibili webpage without requiring video downloads or external processing.
