Short description Turn YouTube and Bilibili videos into study material with captions, bilingual views, AI overviews, Q&A, and timestamped notes.
Detailed description Video Digest AI opens a side panel beside YouTube and Bilibili video pages, turning available captions into searchable, readable, and timestamp-linked learning material.
Key features:
Read original captions, translations, or bilingual text; click timestamps to jump in the video. Generate structured chapters and key takeaways with your own AI provider. Ask follow-up questions about the current video and save useful answers as timestamped notes. Use caption polishing, translation, selection explanation, and editable notes. Configure caption services and AI providers yourself; services fall back in your saved order after recoverable errors. Keep settings, API keys, cached captions, and notes in local extension storage. AI features require an API key from a provider chosen by the user. The extension does not download or transcribe audio locally, and it has no developer-operated backend, accounts, ads, analytics, or telemetry.
