See LikePulse on real videos
LikePulse shows you exactly where YouTube audiences peak — key moments, AI-powered audience analysis, and product detection. On any video, instantly.
Built for viewers and creators who want to understand what really resonates — not just view counts.
Dual-bar chart overlaid on any video. Red peaks show timestamp comments. Blue bars show Most Replayed data. See where audiences actually react.
Automatically detected peaks ranked by intensity. Click any moment to jump directly to that point in the video and see what people said.
Claude Haiku reads the comments and tells you why specific moments resonated, what emotion drove them, and what the creator could improve.
AI automatically identifies products mentioned in the video and finds them on Amazon. Useful for gear videos, tech reviews, and tutorials.
Full UI in English, Spanish, Portuguese, and French — automatically detected from your browser. Works on any YouTube video in any language.
You decide when to analyze. LikePulse never runs automatically — click once and get the full picture. Results cached for 7 days.

LikePulse does not collect, store, or transmit any personal data. The extension operates entirely within your browser.
When you click "Analyze this video", LikePulse fetches public comments via our secure Cloudflare Worker proxy, which calls the YouTube Data API v3. Only the video ID is sent — no personal data or account information.
When AI analysis is requested, a summary of public comments and the video's public transcript is sent to our Cloudflare Worker, which calls the Anthropic API (Claude Haiku). No user identifiers are included. Your personal data is never part of these requests.
When AI detects products in a video, LikePulse may show Amazon links with affiliate tags. Clicking them may earn us a small commission at no extra cost to you. We do not track clicks beyond Amazon's standard affiliate program.
