AdCortex™ neural engagement model
Upload a video or image ad. AdCortex™ scores how strongly it captures attention, second by second, and compares it against 76 proven top-performing ads from the TikTok Creative Center. You get a score, a full breakdown, and an AI-ready report you can paste directly into Gemini for frame-level coaching.
Benchmarked against 76 TikTok Creator Academy top-performers · No opinions · No guesswork
Video or static image — same neural scoring, same benchmark.
TikTok, Instagram Reels, YouTube — any video ad up to 60 seconds.
Packaging, banner ads, print ads, product thumbnails. We convert your image to a 10-second visual stimulus and score it the same way.
Not a single number you don't understand. A full breakdown of what's working and what isn't.
How hard your first 3 seconds grab the brain. Weak hooks lose viewers before your message lands.
The exact second your viewer's brain checks out. Know where you're losing them so you can fix it.
The single highest brain-engagement frame in your video — your best thumbnail candidate.
Neural activation during your CTA window. High activation means the brain is still engaged when you make your offer.
After your score, copy your AI Report and open Gemini. Upload your video alongside the report — Gemini can watch your actual ad and map the neural data against specific frames, giving you precise recommendations: what to cut, what to move, what to reshoot. It's the fastest way to turn a weak score into a strong one.
For static images it goes even further. Upload your banner or packaging shot, get the score, then ask Gemini to redesign it based on the neural data. Gemini generates a new version — you score that one too. Iterate until the numbers move. Users have gone from 46% to 76% late-window conversion signal in three rounds, using nothing but PreTestAds scores and Gemini-generated mockups.
Neural data + video = frame-level coaching
Neural data + AI image generation = a creative testing loop that used to cost thousands
Drag and drop your video or image ad. We handle the rest.
Our neural engagement model analyzes how the brain responds to your ad, frame by frame, and compares it against 76 proven top-performers from the TikTok Creative Center.
