Contentine — YouTube Hook Score

Score any YouTube video's hook out of 100 — right on the page. Free, no signup. Powered by Contentine Analyze.

Stop guessing why your videos lose viewers in the first minute. Contentine's Hook Score adds a one-click "⚡ Hook Score" button to every YouTube video. Click it and our AI watches the first 60 seconds of the actual footage — scenes, on-screen text, and audio — then grades the hook out of 100 across four dimensions: Clarity, Curiosity, Pacing & Energy, and the critical First 5 Seconds. You get a verdict, a score breakdown, and the top insight in about 30 seconds. No signup, no credit card. It works on your own videos and on your competitors' — right-click any YouTube link to score it, or use the toolbar button on the video you're watching. Why it's different: this isn't a metadata or SEO tool. It analyzes the footage itself — what the viewer actually sees and hears in the opening seconds — because that's what decides whether they stay.
