HookScore

HookScore is a mobile + web AI app that lets TikTok and short-form creators scientifically test their first 3 seconds before wasting time on full videos. Creators upload multiple rough hook variants (text, storyboard, or quick selfie clips). The app auto-generates simple test creatives, pushes them as unlisted or dark posts via ad APIs, and spends a tiny budget to measure real scroll-stop rate, watch time, and tap-through. Instead of guessing which idea will pop, creators get a ranked list of hooks with predicted performance scores and audience breakdowns. It’s not glamorous: you’ll be told most of your ideas are trash, and that’s the point. The app focuses only on the most critical part of TikTok success—the hook—rather than bloated “all-in-one creator suites” that nobody fully uses. This is for creators who care more about numbers than vibes, and are willing to spend a few dollars to avoid posting duds in public.
