What you get free
A real second opinion on your ad — before you spend a dollar.
Most ad testing requires you to launch the ad, burn budget, and wait two weeks for statistical significance. Kettio’s free ad analyzer flips that. Upload two creatives and a simulated buyer persona reads them, reacts in plain English, and tells you which one would convert — in under 30 seconds. No spend, no waiting, no guessing.
The free tier covers the most common DTC ecommerce ad formats: Meta feed images, TikTok in-feed, Google Display, LinkedIn single image, Amazon Sponsored Brands, Reddit Promoted Posts, and Pinterest Standard Pins. Pick your platform, pick the objective (Sales, Engagement, Awareness, Traffic, etc.), and pick the persona reacting.
When you create a free account you get 10 free credits to keep running ranked simulations — plus unlock copy testing (score image + headline + CTA together), custom audiences built from your real buyer profile, and saved run history.
Why it’s different
Calibrated against real CTR. Not vibes.
Every other “AI ad analyzer” outputs a vague score from a single model with no validation. Kettio’s scoring engine — SSR, short for Silicon Survey Ranking — runs a two-model ensemble (Flash + Haiku) for each ad, embeds each generated reaction with text-embedding-3-large, and compares each embedding against anchor reference texts on a 1–5 scale.
The result is a calibrated score with a confidence label — not a hallucinated number. We’ve validated SSR against the University of Washington ad-perception survey (ρ=0.775, n=160), the ADS-16 benchmark, and the CreativeRanking real-CTR panel. That’s why the conviction chip on your result is honest about how decisive the call is.
The methodology section below covers the full anti-SDR (social desirability) framing, generator temperatures, and anchor calibration approach. If you want the deep-dive, read on — if you just want to test an ad, scroll up.
How Kettio decides
Not a chatbot answer. A scoring system.
The trust layer is the method: render the audience response, transform it into calibrated score evidence, then choose the winner from the distribution.
01 Response render
We simulate the panel before we score it.
Kettio first renders persona-specific reactions in the right context: audience, platform, objective, image, video, and optional ad copy layer.
02 Signal routing
Visual, copy, and package scores stay separate.
The scorer knows whether it is judging the image alone, copy alone, or the full deployed ad package, so hidden copy does not leak into visual-only rankings.
03 Score construction
Rationales become distributions, not vibes.
Rendered reactions are normalized, embedded, and compared against objective-specific anchor banks to produce a Likert probability distribution and expected score.
04 Winner selection
The winner is chosen from the score evidence.
Kettio aggregates samples, compares margins, records confidence signals, and flags close calls instead of pretending every result is equally certain.
