Video AI Summarizer

Summarize YouTube and Bilibili videos with timestamped notes and configurable AI providers. Video AI Summarizer helps you turn long YouTube and Bilibili videos into structured, timestamped notes without leaving the video page.

Unlike subscription-based summarizer extensions, this extension lets you use your own AI API key. You stay in control of the model, cost, and output quality.

Key features:

• Summarize YouTube and Bilibili videos directly on the video page
• Timestamped bullet points that you can click to jump to the relevant moment
• Clean, minimal UI designed to blend naturally with YouTube and Bilibili
• Auto-summarize when opening a new video
• Responsive panel size that stays aligned with the video player
• Dark mode support
• Collapsible summary sections for quick scanning
• Bring your own API key
• Continue deeper discussion with transcript context pre-filled
• Settings can sync across browsers when browser sync is available

This extension is built for people who watch lectures, interviews, podcasts, tutorials, reviews, and long-form videos, and want the key points without losing access to the original context.

Note: The extension requires video captions/transcripts to generate summaries. AI API usage may incur costs depending on your provider.
