YouTube AI Summarizer

YouTube AI Summarizer とは？

Stop watching on 2× speed. YouTube AI Summarizer turns any video into a 3–5 paragraph summary, 10 key points, section-by-section analysis, a two-host AI podcast (WAV download), and a follow-up chat — in 20+ languages. Two modes: Managed AI (free credits, optional Pro) or BYOK — bring your own Groq, Gemini, or Ollama key. Your data never touches my servers. No ads. No trackers. MIT licensed. MV3, vanilla ES6, zero build step.
