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 reads your buyer
Not a chatbot guess. A real read on your buyer.
The method is the trust layer: render how your buyer reacts, pin down exactly where that lands on the scale, then surface the winner — and the line where they hesitate.
01 The read
We put your ad in front of your buyer.
Kettio renders how your specific buyer reacts in context — audience, platform, objective, image, video, and the optional ad-copy layer.
02 Image, copy, full ad
We read the visual, the copy, and the full ad separately.
Kettio knows whether it is reading the image alone, the copy alone, or the full deployed package — so hidden copy never leaks into a visual-only read.
03 Where they land
Their reaction becomes a place on the scale.
Each reaction is normalized, embedded, and compared against objective-specific anchor banks — so you see exactly where your buyer lands, not a vibe.
04 What wins, and where it hesitates
The winner is the one your buyer actually leans toward.
Kettio weighs the margin, records confidence, and flags the close calls — instead of pretending every read is equally certain.
