  Wisdom is a free Chrome sidebar that summarises YouTube videos using AI. One click extracts structured notes — key insights, quotes, takeaways, facts, tools, references, and recommendations — from any video with captions.
  No copy-pasting transcripts into ChatGPT. No switching tabs. It all happens right next to the video.
  
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  ✦ WHAT YOU GET FROM EVERY VIDEO
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  • One-sentence summary — the core idea in 25 words
  • 12 main points — the most important ideas, distilled
  • 6 key takeaways — actionable, concrete next steps
  • Notable quotes — the lines worth remembering
  • Tools & references — everything the speaker mentioned
  • Interesting facts — details you'd otherwise miss
  • Wisdom Score — a 1-100 rating of the video's educational value
  
  All generated in seconds. All structured. All saved.
  
  ━━━━━━━━━━━━━━━━━━
  ✦ FIVE CORE FEATURES
  ━━━━━━━━━━━━━━━━━━
  
  📌 AI WISDOM EXTRACTION
  Click "Extract Wisdom" and the AI reads the full transcript, then returns structured notes organised into clear sections. Powered by Gemini 2.5 Flash (free tier) and Claude (signed-in users). No API key needed.
  
  📜 SEARCHABLE TRANSCRIPT
  Full video transcript with timestamps. Search for any word or phrase. Click a timestamp to jump to that exact moment in the video. Faster than YouTube's built-in captions.
  
  💬 CHAT WITH THE VIDEO
  Ask questions about the video content and get answers grounded in the actual transcript — not hallucinated. Great for lectures, tutorials, and long-form content.
  
  📊 COMMENT ANALYSIS
  AI analyzes the comment section: overall sentiment (positive/neutral/negative), key themes, top commenters, and highlighted comments worth reading. See what the audience thinks without scrolling through hundreds of comments.
  
  📚 PERSONAL LIBRARY
  Every extraction is automatically saved. Search, sort (by date, title, channel, wisdom score), and browse your history in grid or list view. Your own knowledge base, built one video at a time.
