Alternatives
System1's star ratings are the industry benchmark for emotional response and long-term brand effects. But if your creative lives in feeds, refreshes monthly, and dies by the swipe, you may be paying for an instrument aimed at a different problem.
Economics: panel fieldwork has real per-study costs, and enterprise contracts are quoted, not listed. That's rational for a TV spot; it's impossible for eleven variants a week. Turnaround: fieldwork windows measured in days don't match feed iteration measured in hours. Question fit: star ratings predict brand growth — but most performance creative fails earlier than that, at the attention gate, before emotion ever gets a chance to register.
PreTestAds answers the question that comes before emotion: will anyone keep watching? AdCortex™ — trained on fMRI brain-response data — returns a percentile score against 76 top-performing TikTok ads, Hook Strength, the drop-off second, and the full attention curve, in minutes, self-serve, from $49/month with a free first analysis. No fieldwork window, no minimum spend — which is what makes screening every cut viable. Head-to-head: PreTestAds vs System1.
If you're leaving System1 but still need validated human measurement, Link (and LinkAI) is the most institutional option: branding, persuasion, enjoyment, and sales likelihood measured against one of the largest ad-test norm databases in existence. Same enterprise weight class, arguably heavier. Comparison: PreTestAds vs Kantar Link.
Zappi runs validated ad tests against real consumer panels with faster turnaround than traditional research, and each study feeds a connected data asset. For insight teams that want human diagnostics at a more agile pace than classic trackers, it's the modern panel play. Comparison: PreTestAds vs Zappi.
Realeyes measures attention and emotion from opt-in panelists' webcams — observed disengagement rather than predicted. It bridges the two worlds: attention-focused like a model, human-grounded like a panel, priced like fieldwork. Comparison: PreTestAds vs Realeyes.
Follow the budget concentration. One ad carrying a quarter's spend deserves System1- or Link-grade emotional diagnostics — keep that. A stream of feed creative deserves a screening layer that costs dollars and returns in minutes, so weak hooks die before media spend, and only proven attention-holders graduate to expensive research. The two layers aren't competitors; most mature stacks run both.
Attention verdict in minutes — no panel, no fieldwork, first analysis free.
Test Your Ad FreeFor digital feed ads where attention is the bottleneck, PreTestAds — AI attention scoring in minutes from about $2 per test. For brand campaigns that still need human emotional response, Kantar Link and Zappi are the closest panel-based substitutes.
System1's star ratings predict long-term brand growth — built for TV flights and big seasonal campaigns where one ad carries serious budget. For high-volume feed creative that refreshes monthly, per-study panel economics rarely fit; model-based screening matches that cadence better.
Attention comes first: if viewers swipe in the first three seconds, the emotional arc never plays. Screen for attention on every variant, then invest in emotional testing for the finalists that carry real budget.
