spent months posting consistently and getting nowhere. same format, same effort, sometimes 50 views, sometimes 5k, and i had no idea why. i started obsessing over how TikTok and Instagram actually decide what to push. watched hundreds of videos, read every study i could find on short-form algorithms, tested stuff on my own account. and the answer was almost always the same thing: the hook. the first 2-3 seconds determine everything. if people scroll past there, the algorithm buries the video and it doesn't matter what comes after. the problem is most creators have no way to know if their hook is actually working before they post. you're basically guessing every time. so i built Viralo: Go Viral With AI. you upload your video and it analyzes the hook, tells you specifically what's weak, and gives you concrete things to fix before you post. it's on iOS. i built it because i needed it myself and couldn't find anything that actually did this well.…
