About the product
neuro-viral shows the predicted brain response to a video, second by second, before you publish it.
Paste a YouTube link or upload a file (MP4, MOV, WebM or AVI). Our model, v2neuro, is a brain-encoding model trained on fMRI recordings. It predicts the average cortical response to your video and gives you:
- a second-by-second predicted response curve with peaks and steepest falls marked
- which brain systems lead each moment (auditory, visual, speech, scene and more)
- a 3D cortical map you can rotate
- a trust score for every second
- an AI editor that cuts, trims and rewords the weakest stretch, explains every change, and lets you compare the new cut against the old one
Built for YouTube, Shorts, TikTok and Reels creators, small brand teams checking video ads before spend, and agencies.
What it can't do: it predicts an average brain, not your audience, and it is not a performance forecast. We publish our limits.
Free: one scan a month, up to 60 seconds, no card. Creator $29/month (first 50 members $19/month), Studio $119/month, Agency $299/month.
