Virality Predictor is an AI-powered web app that scores the viral potential of any short-form video before you publish. Drop in a clip up to 20 seconds and get a 0–100 viral score, hook strength, predicted hold rate, and a second-by-second attention curve — typically in under a minute. Built for performance marketers, social-media managers, and creators who pretest TikToks, Reels, and Shorts before they hit publish. No subscription, no install: pay-as-you-go credits, web-app only.
