AI Video Insight: YouTube Summary & Notes

Summarize captioned YouTube videos in a sidebar: 3 styles, mind maps, chapters, study notes and an SEO kit.

AI Video Insight turns YouTube videos with available subtitles into structured summaries you can use while the video stays on screen. SUMMARY Choose Standard, Academic, or Practical. Get key ideas and a clickable chapter timeline to revisit the exact moment that matters. MIND MAP Explore the video's main themes in visual or outline view, then export to Markdown or XMind. STUDY AND CREATE Generate study notes with Markdown and Anki exports, or an SEO Pack with keyword ideas, titles, a description, tags, audience insights, and an opening hook. SUBTITLES View, search, copy, and download available YouTube captions as SRT or TXT. If a video has no available subtitles, the extension tells you clearly and offers a prompt you can paste into Gemini yourself. LANGUAGES AND CREDITS Output is available in English, Simplified and Traditional Chinese, Japanese, Korean, Spanish, French, and German. Free accounts receive 150 lifetime AI Credits. Pro includes 5,000 Credits per billing month, subject to a 500-Credit daily cap. Each AI generation uses 10 Credits per started 30 minutes of video; cache hits and failed generations do not use Credits. AI generation requires an available YouTube subtitle track and starts only when you choose to generate. Subtitle text is sent for processing when you start an AI generation.
