Anatomy of a scoring result.
One screen. Three scores. Six brain-network metrics. A narrative. Click a moment to seek.
Three steps. Real product. No spreadsheets.
Upload winners and losers, per brand.
Drop in the ads you know performed and the ones that didn't. Three of each is the minimum — Cortex learns from your weights, your labels, and your actual creative.
A brand-specific signature, validated against itself.
Cortex holds out each reference one at a time and re-scores it. The gap between winner and loser distributions is the proof — and references that disagree with their own label get flagged for review.
Score a candidate. See exactly where it lands and why.
Final score, brand winner-likeness, attention pull, and confidence — plus a brain-activity timeline, per-moment element scores, and a written narrative pointing at the seconds that drive or drain performance.
The brain math, translated into something a creative director can act on.
Every scoring includes a structured analysis — what's working, what's weaker, and concrete recommendations tied to specific seconds of your ad. No neuroscience jargon.
The opening hook lands like your top-quartile winners.
The first 3.6s scores 91; attention and focus both peak above 80.
The product demo at 0:12-0:15 stalls.
Desire plateaus through the beat where winners typically peak.
Replace the static product demo with a use-in-context shot.
Movement and real-context framing tend to fix the desire gap.
One workspace. Every brand. Each with its own brain.
Agencies and in-house teams keep a separate signature per brand. Switch contexts in two clicks; quotas roll up at the workspace level.
Find the references in your library that are lying to you.
Every signature build returns a per-reference report: which ads scored consistent with their label, which ones didn't, and which are too ambiguous to trust. Re-label, downweight, or drop — your scoring sharpens accordingly.
What we measure, in plain English.
Cortex tracks six independent dimensions of the predicted brain response. Each one tells you something different about how your ad lands.
How much your ad pulls focus in the moment — the visual-cortex pull that determines whether a thumb stops scrolling.
Sustained looking. Distinct from attention: attention catches the eye, focus holds it on a specific element.
Reward-system activation. The 'I want that' signal that turns interest into intent.
Executive-control firing. Where the viewer's prefrontal cortex commits to (or rejects) the proposition.
Self-referential activation. Does the viewer see themselves in the ad — does this product feel like it's for them?
Body / motion network. Tracks bodily and somatomotor engagement — the dancing-along effect.
“We were spending $40k a week to find out which creatives worked. Cortex tells us before the creative ever leaves the edit bay.”
