Virality predictor
Will your video stop the scroll? Upload a TikTok, Reel, Short or ad: a virality score, how strong the hook is, where viewers swipe away and what to fix.
What you get
- Virality score, 0-100Weighted the way feeds decide: the first 3 seconds count the most, then pacing, the product, sound, captions, the payoff and the platform fit.
- Hook strength and the 3-second holdWhat the first frame shows, when the product appears and how many viewers are likely still watching at 3 seconds.
- A second-by-second retention curveWhere attention dips and the exact moments viewers are likely to swipe away, with the reason seen at that moment.
- The 3 fixes that matter mostConcrete edits with the second they apply to, most important first.
How it works
- We measure the video ourselves: every cut, every still stretch, silence and speech pace.
- An AI model watches the whole video with its sound and scores it against the rules short-video feeds reward.
- The measurements overrule the model: a still, silent opening can never come back as a strong hook.
The score and the curve are an estimate built from these rules, not a guarantee of views.
