neuro-viral: see where viewers lose interest before you publish

neuro-viral is an AI tool that predicts where the average viewer's attention rises and falls in your video, second by second, before you publish it. Paste a YouTube link or upload a file and our AI, trained on public brain-scan data, produces an attention chart and an interactive 3D brain map with plain-language insights for creators, brands and marketers.

What neuro-viral does

Interactive 3D brain map: navigate a live brain surface; every region is labelled, coloured by predicted activity, and explained in plain language.
Second-by-second attention chart: see where predicted attention peaks and where it dips, with weak-second alerts.
Compare two edits: upload two cuts and see which one is predicted to hold attention better, second by second.
Word-level transcript and sensory arc: tie each spoken moment to its predicted attention.

How it works

Paste a YouTube URL or upload a video (MP4, MOV, WebM, AVI).
An AI model of vision, audition and language, trained on public fMRI brain recordings, predicts the average viewer's attention for each second.
Explore the result as an attention chart and an interactive 3D brain map with plain-language insight. Your first scan each month is free, no card required.

Frequently asked questions

What is neuro-viral?

neuro-viral is an AI tool that predicts where the average viewer's attention rises and falls in a video, second by second, before you publish it. It is shown as an attention chart and an interactive 3D brain map with plain-language insights. It is a prediction, not a performance forecast.

How does neuro-viral predict attention?

It uses an AI foundation model of vision, audition and language, trained on public fMRI brain recordings, to estimate how the average viewer's attention rises and falls across each second of your video.

Do I need a neuroscience background to use it?

No. neuro-viral turns the predicted brain activity into a clear attention chart and plain-language insights you can act on right away.

Is the first scan free?

Yes. Your first scan each month is free with no card required, so you can see your video's predicted attention chart before subscribing.

What videos can I scan?

Any short video. Upload a file or paste a YouTube link. Each scan covers up to the first few minutes of the clip.
