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。
