Hook Checker — score, decode, and rewrite any hook
Drop in your hook and we'll score it the way a retention model does: curiosity gap, pattern interrupt, dopamine pacing, and first-3-seconds pull. You get a 0-100 score, the exact reasons it works (or doesn't), and three sharper rewrites you can ship today.
We score curiosity, clarity, emotional pull, and pattern interrupt on the same axes Shorts and TikTok retention curves reward.
Get the psychology behind the hook — not just a number. Use it to repeat what works and cut what doesn't.
Every check ends with three production-ready rewrites tuned for first-3-second retention.
