ScrollSonar

ScrollSonar is a short-form video research tool for TikTok, Instagram Reels and YouTube Shorts. Type a niche, or paste your website or App Store link, and it pulls live public data to show the hooks and formats getting views right now on all three platforms.

Videos are ranked by views compared with each creator's own median, so you see what actually broke out rather than what big accounts posted. Every result links to the original post.

It also finds the small creators making those videos, with the business email they publish in their public bio, and writes briefs and scripts for your product based on what is working.

Built for app and SaaS founders, brands, agencies and performance marketers. Six free tools (such as a TikTok hook checker and video ideas for your app) work without an account. Paid plans start at $19/month with a 3-day free trial.
