YouTube Summary AI is a free Chrome extension that turns hours of YouTube into seconds of reading.

You can also send the full transcript to ChatGPT, Claude, Grok, or Gemini in one click for follow-up questions, translations, or deeper analysis. What makes YouTube Summary AI different? Most YouTube summarizer extensions just open ChatGPT in another tab. We do that AND give you a free built-in AI summary — no signup, no API key, no account required. Three free summaries per day, unlimited handoffs to your favorite AI. How do I summarize a YouTube video? 1. Open any YouTube video with captions. 2. Click the green ✨ Summarize button next to YouTube's search bar. 3. A summary slides in from the right with 5–10 bullet points, each starting with a clickable timestamp like [1:23]. 4. Click any timestamp to jump the video to that moment. No copy-paste, no manual prompting, no second tab.
