hear what they don't say.
Upload a video. NeuroVidz reads how a brain responds to its picture and its sound — attention, engagement, and emotion, second by second — then shows the exact moment attention slipped and the edit to make. Most tools only watch the frames; we listen too.
Attention holds through the hook, then dips at 0:14 — tighten the middle beat and lead with the payoff.

Most tools are half-deaf.
Sound is half of engagement — the voice, the music, the beat drop, the silence before a punchline. Other tools only watch the frames. NeuroVidz listens too.
A flat talking-head and a gripping one score the same — because the audio never enters the read.
Energy, rhythm, voice and silence feed the read — so podcasts, music, and voice-driven clips finally get a score that reflects what a listener actually feels.
A read you can act on.
