For Political & Advocacy Teams
Campaign world has the most sophisticated persuasion testing in advertising — randomized trials, message experiments, nightly tracking. All of it assumes one thing the feed doesn't guarantee: that anyone watched. The attention gate is testable in minutes, and on a campaign clock, minutes is the only unit that fits.
Platforms like Swayable answer the campaign's highest-stakes question — did this content move opinion? — with experimental rigor (see Swayable and its alternatives). But in a paid feed, the spot that tested brilliantly still has to stop a thumb cold, and that decision happens in seconds, before a single argument lands. An ad that loses the scroll persuades no one, at any level of message quality.
AdCortex™, trained on fMRI brain-response data, scores a finished spot in minutes — Hook Strength, the exact second attention drops, a percentile against 76 top-performing short-form ads. That pace fits the reality of a war room: the cut that ships tonight can still get a pre-spend check this afternoon, and the digital team can rank five versions of the closing ask before the buy locks. Works on any finished spot — filmed, designed, or AI-generated.
Trials cost study money and days; screening costs about $2.45 per spot and minutes. The efficient split mirrors what performance teams do with A/B budgets: attention-screen every cut and cutdown, then spend trial budget only on message questions for spots that already hold. Donation and GOTV creative follows the same logic — the ask only works on viewers still present for it.
This tool measures attention, not truth, persuasion, or compliance. Disclaimers, claim substantiation, and each platform's political-ad rules stay with counsel — the same boundary we draw for regulated-category ads. Score the compliant cut you'll actually run. And the methodology is public, which matters in a field where every vendor claim eventually gets scrutinized.

No. Persuasion lift is measured by randomized-trial platforms like Swayable, with real audiences and real timelines. PreTestAds measures the gate in front of persuasion: whether a feed viewer keeps watching long enough for the message to land, scored second by second from the creative alone.
Because campaign creative ships in days, not quarters, and rapid-response spots ship in hours. Fielding a study on every cut doesn't fit that clock. A model screen returns in minutes, so even the spot written this morning gets a pre-spend check before the buy goes live.
No — and that boundary matters. Paid-for disclaimers, claim substantiation, and platform political-ad policies stay with counsel and your compliance process. The score only answers whether the approved cut holds attention. Test the compliant version you'll actually run, not the one you wish you could.
