How the gate works
How the Short-Form Hook & Retention gate works
This tool grades a short-form video hook before you post it. It scores 6 weighted controls into a 0–100 number — then a gate that can only make the verdict worse.
The 6 weighted controls
If the promise doesn't match the payoff (that criterion at 0), the verdict is forced to REWORK regardless of the score. A hook that overpromises wins the scroll-stop and then tanks retention when the video can't deliver.
Why: Every other criterion is maxed — score 80, which reads SHIP. But the promise doesn't match the payoff (0), and that's the gate: it's forced to REWORK. A hook that overpromises wins the scroll-stop and then bleeds viewers the second the video can't deliver what the hook sold.
A high score didn’t save it. The score is context; the gate is the answer — and it names the one thing to fix first. Scores the hook, not the creator. Runs offline in the workbook — no platform data pulled.
