Upload a short clip and get a modeled read on its hook strength, attention curve, and viral potential.
Virality Predictor is in beta. Max video duration is 90 seconds, up to 100 MB.
How it works
Drop the clip
A hook you're testing, an ad before launch, a reel sitting in drafts. Any format, vertical or horizontal, up to 15 seconds.
We analyze
A modeled audience watches while we map the brain response across vision, sound, memory, attention, language.
See results
A virality score, a peak hook timestamp, a hold rate, and a heatmap showing exactly which regions of the brain your clip is firing.
Engagement score
One number for how long people will actually watch. Not a guess, not a vibe check — a modeled read on whether your clip earns the scroll or loses it. The closest thing to a test screening before you hit publish.
