LikePulse

Find peak moments on YouTube using comment spikes, Most Replayed data, and AI audience analysis. Affiliate links may appear.

LikePulse shows you exactly where YouTube audiences react — so you never miss the best moments in any video. ── WHAT IT DOES ── ▸ Engagement Heatmap Dual-bar chart overlaid on every video. Red bars show where viewers wrote timestamp comments ("3:31 amazing!"). Blue bars show YouTube's Most Replayed data. See both signals at once. ▸ Key Moments — Click to Jump Automatically detects peaks in audience activity. Click any moment to jump directly to that point in the video and read what people said. ▸ AI Audience Analysis Claude AI reads the comments and tells you: what happened at each peak, what emotion drove it, and what the creator could improve next time. ▸ Product Detection AI identifies products mentioned in the video and finds them on Amazon. Affiliate links may appear. ▸ 4 Languages Full UI in English, Spanish, Portuguese, and French — auto-detected from your browser. ▸ Analyze on Demand You decide when to run the analysis. LikePulse never runs automatically in the background. ── HOW IT WORKS ── 1. Install LikePulse (no account needed) 2. Open any YouTube video 3. Click "Analyze this video" 4.
