Retention graphs for Shorts all share one feature: a cliff in the first two seconds. Whatever the video is about, the opening line decides how steep that cliff is — which makes the hook the highest-leverage sentence you'll write. It's also the cheapest one to fix: rewriting a hook is free, rewriting a video isn't.
The analyzer is deliberately not an AI. Five plain rules — length, specificity, curiosity, viewer address, punch — each shown with the exact reason and a concrete fix. A rule-based score is reproducible: change the thing it names, run it again, and the number moves because the writing changed, not because a model rolled differently.
By five plain rules — length, a specific number, a curiosity trigger, whether it addresses the viewer, and a punchy start. Every point is explained on the page; there's no AI grading it.
A tight line (roughly 4–12 spoken words) that opens a curiosity gap, names something specific, and talks to the viewer — with no 'so, today I want to…' throat-clearing before it.
No. The analyzer runs entirely in your browser. Your hook never leaves the page.
