Hook score
0–100 neural engagement score for your opening hook
Brain timeline
Second-by-second activation chart across visual cortex, amygdala, and attention networks
3D brain heatmap

Drop-off diagnosis
The exact frame where brain engagement drops — and why
TikTok's algorithm rewards videos that retain viewers past 3 seconds. Our brain analysis shows you exactly which frame triggers the decision to keep watching — or swipe away.
