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.
