Virality Score
An AI prediction (often 0–100) of how likely a clip is to perform, based on hook, pacing and retention signals.
A virality score estimates a clip's odds of taking off before you post it, by scoring signals that correlate with performance — how strong the opening hook is, how tight the pacing feels, and how well it's likely to hold attention. It turns 'which clip should I post?' from a guess into a ranked decision.
ChunkyMonkey scores every clip it cuts and ranks them best-first, so you lead with your strongest moment.
