Wisdom: YouTube Summary & Transcript AI

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.
