Zappi made panel research agile — templated ad tests, connected learning across studies, results in hours instead of weeks. PreTestAds removes the panel entirely. Whether that's an upgrade or a different product depends on the question you're asking.
Zappi is an insights platform: validated ad-testing templates run against real consumer panels, with results that accumulate into a connected data asset so each test makes the next smarter. Enterprise insight teams at major CPGs use it to democratize research that used to bottleneck through agencies. You get human reactions — comprehension, appeal, distinctiveness, purchase intent — at a pace traditional research never managed.
PreTestAds trades the panel for a model: AdCortex™, trained on fMRI brain-response data, predicts second-by-second engagement and benchmarks your ad against 76 top-performing TikTok ads — in minutes, for a credit, no recruitment or fieldwork at all. The output is surgical for creative work: Hook Strength, the exact second attention drops, the peak frame for your thumbnail, and a report built to feed the generate-score-regenerate loop.
A panel can tell you an ad is well-liked and clearly understood — and that ad can still die in the feed because likability is measured with a captive audience and feeds don't have one. Attention is the gate in front of every other metric: no hold, no comprehension, no persuasion, nothing. The disciplined stack uses a model to verify the gate and panels to explain what happens beyond it — the same logic as pre-testing vs focus groups, industrialized.
Choose Zappi if you're an enterprise insight team building a connected research program with panel depth across concepts, packs, and ads. Choose PreTestAds if you're a creative or growth team that needs a same-hour attention verdict per variation at self-serve prices — or if your volume of UGC and AI-generated cuts makes per-study economics impossible. The two coexist happily at different layers of the funnel.
Score every variation in minutes before deeper research — up to 8 free credits.
Test Your Ad FreeFor fast attention screening without panels, yes — minutes per test, self-serve, up to 8 free credits. Zappi remains the stronger choice for enterprise insight programs needing human panel diagnostics connected across studies.
Zappi runs real consumer panels through validated templates — human answers, hours-to-days turnaround, enterprise platform pricing. PreTestAds predicts attention with an fMRI-trained model — no humans recruited, minutes turnaround, per-credit pricing.
Panel likability is measured with a captive audience; feeds are not captive. If an ad does not hold attention in the first seconds, viewers never reach the parts panels liked. Attention screening verifies that gate before deeper metrics mean anything.
