YouTube Hook Analyzer — score any opening in seconds
Paste a YouTube URL or just your opening line. We score the hook on the same retention axes the algorithm rewards — curiosity gap, promise density, pattern interrupt, first-3-second pull — and return a 0-100 hook IQ with three production-ready rewrites.
Long-form and Shorts
Works for cold opens on long-form and for the entire opening of a Short.
Retention prediction
Predicts where viewers drop off in the first 30 seconds so you can pre-fix it before publishing.
Three rewrites
Each analysis ends with three sharper rewrites you can A/B test.
Frequently asked
Do I need to upload my video?
No — paste the YouTube URL or just the opening line. Both work.
What's a good hook IQ?
80+ is publish-ready. 60-79 means rewrite. Below 60, restart from the angle.
