ViralAri vs Sandcastles
Sandcastles.ai and ViralAri both explain why short-form videos perform and both generate hooks. They point in different directions. Sandcastles looks outward: it finds outlier videos across Instagram, TikTok and YouTube Shorts, explains why they performed, and generates hooks and scripts from that high-view content. ViralAri looks inward: it reads your own last 30 posts, scores each against your own baseline, and generates hooks in your voice. Plenty of creators would get value from both.

- You want to know why your own posts won or lost, scored against your own baseline rather than against strangers' outliers.

What ViralAri does not do, stated plainly: Instagram and TikTok only (no YouTube), no scheduling, no editing, no cross-niche trend feed today, and no retention curves, because Instagram does not expose them. Competitor details are from their public pages and can change; check their site for current pricing.
