description

Summarize YouTube videos using your favorite AI provider: Gemini, DeepSeek, or OpenAI.

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. 

------------------------------------------------------------------------------------------------------------------------------------------------------------

Video AI Summarizer 可以把 YouTube 和 Bilibili 长视频整理成结构清晰、带时间戳的摘要笔记，并且直接显示在视频页面里。

市面上很多视频总结插件要么订阅制，要么免费模型效果有限，要么界面过于突兀。这个插件的目标很简单：用你自己的 AI API key，按你想用的模型生成真正可读、可跳转、和视频页面融为一体的总结。

主要功能：

- 直接在 YouTube 和 Bilibili 视频页面生成摘要
- 支持带时间戳的 bullet points，点击要点即可跳转到对应视频位置
- 极简 UI，尽量贴合 YouTube 和 Bilibili 原生页面风格
- 打开新视频后可自动触发总结
- 摘要面板尺寸自适应，和视频播放器保持对齐
- 支持深色模式
- 支持折叠详细内容，方便快速浏览
- 使用你自己的 API key，不绑定订阅制
- 可以一键继续深入提问，并自动带上字幕上下文
- 设置可在浏览器支持的情况下自动同步

适合用来看课程、访谈、播客、教程、测评和各种长视频。你可以快速抓住重点，同时保留跳回原视频上下文的能力。

说明：
插件需要视频本身有字幕或 transcript 才能生成总结。AI API 的调用费用取决于你使用的 provider。
