Is PreTestAds a good Neurons alternative?

For short-form video and image ad testing, yes — PreTestAds predicts second-by-second brain engagement with an fMRI-trained model, benchmarks against 76 top TikTok ads, and is self-serve with a free first analysis. Neurons remains a strong choice for enterprise teams needing spatial heatmaps and brand norms.

What is the difference between PreTestAds and Neurons?

Training signal and output. Neurons' models are grounded in eye-tracking research and excel at predicting where people look. PreTestAds' AdCortex is trained on fMRI brain-response data and predicts whether engagement holds over time — a temporal attention curve rather than a spatial heatmap.

Do PreTestAds and Neurons require a sales call?

Neurons is sold as enterprise SaaS with demos and contracts. PreTestAds is fully self-serve — create an account, upload an ad, first analysis free — and also offers a pay-per-call API that requires no account at all.

Comparison

PreTestAds vs Neurons

Neurons and PreTestAds sit in the same corner of the market: neuroscience-trained AI that predicts how people respond to creative, no panel required. The differences are in what the models learned from, what they hand back, and who they're priced for.

What Neurons does well

Neurons is a Copenhagen neuroscience firm whose Predict tool estimates attention and engagement on images and video, built on years of eye-tracking and neuro research — with heatmaps, focus metrics, and enterprise features like brand norms and team workflows. It's a serious, well-validated platform used by large brands and agencies, and its visual-attention heatmaps are excellent for layout and design questions.

What PreTestAds does differently

PreTestAds runs AdCortex™, a model trained on fMRI brain-response data — predicting whole-brain engagement over time rather than where eyes land in space. Output is built for the feed era: a percentile score against 76 top-performing TikTok Creative Center ads, Hook Strength for the first 3 seconds, the exact drop-off second, peak frame, and a second-by-second attention curve. The question it answers isn't "where will people look?" — it's "will they keep watching to your CTA?" (Full detail on the model in our methodology.)

Pricing and workflow

Neurons is enterprise SaaS — demos, seats, annual contracts — which makes sense for its depth. PreTestAds is self-serve: sign up, upload, credits, first analysis free. There's no sales call between you and a score, and an x402 pay-per-call API means even an AI agent can buy a single scoring run with no account at all. For freelancers, DTC brands, and small-budget testing programs, that difference is the whole decision.

Which should you choose?

Choose Neurons if you're an enterprise team that needs spatial attention heatmaps, brand norms, and vendor depth across many design surfaces. Choose PreTestAds if you make short-form video and image ads, want a benchmarked verdict plus a fix-it diagnosis in minutes, and want to iterate AI-generated variations at a per-credit price. Plenty of teams could justify both: heatmaps for layout, attention curve for the edit.
