Methodology

The Glass Box

Ad Corrector is built for verification. We do not use AI models to judge your creative. We use deterministic algorithms that measure visibility and first impression strength using repeatable rules. Same input in, same output out.

Deterministic results
No LLM scoring and no generative opinions
Built for OOH speed and distance reality
What we understand: AI is great for creating, but risky for verification. Before you spend real money on real media space, you want a safety check that does not improvise.

Black Box vs Glass Box

Many AI analysis tools are black boxes. You upload an image and get a confident sounding verdict, but you cannot see the rules underneath it. Ad Corrector is a Glass Box. We use measurable signals and fixed logic that stays consistent.

Feature Black Box Typical AI Opinion Tool Glass Box Ad Corrector
Core engine Probabilistic model output Deterministic measurements and rules
Output Generated commentary that can vary Scores, signals, and fixed guidance
Consistency Can shift between runs Same input produces the same results
Risk Confident sounding uncertainty Limits are explicit and measurable
Goal Pleasing feedback Truthful constraints for visibility
We are not against AI, what we focus on is truth. Creation and verification are two different jobs.

Step 1 Ad Corrector

Step 1 measures visibility risk using deterministic signals. We measure what will be harder to see, read, or process fast.

1) Speed View

A motion-visibility simulation built for fast scanning. It uses viewing inputs (mph and distance) to show what details survive when the viewer has seconds.

2) Attention map

An attention proxy that highlights where structure and contrast concentrate first. It helps reveal when your headline is not visually dominant.

3) Contrast and clarity signals

Contrast is estimated using luminance sampling. Clarity combines edge strength and viewing constraints to identify readability risk.

Important: These are engineering checks designed for speed and distance reality. They are repeatable and they do not change based on mood, prompting, or interpretation.

You can evaluate your creative against these visibility signals by running a free billboard test with Ad Corrector.

Step 2 Persuasion Engine

Step 2 translates Step 1 visibility signals into a first-impression response score. It shows how viewers will feel in the first 1 to 2 seconds based on what the creative communicates immediately.

How it works

  • Consumes Step 1 scores and signals like clarity, contrast, composition, color impact, and CTA strength.
  • Applies fixed weights to compute five fast-response metrics (0 to 10).
  • Outputs a composite persuasion score (0 to 100) and practical fix-first guidance.
Deterministic again: same Step 1 inputs produce the same Step 2 results. This is a scoring and translation layer.

What you get from the Glass Box

The system is built to reduce avoidable failure before you spend money on media. Outputs are designed to be actionable without requiring interpretation.

Measured constraints

Visibility signals, contrast risk, and fast comprehension pressure points that explain why a message will struggle at speed.

Prioritized fixes

Clear, ordered guidance focused on the few changes that move the needle most for OOH readability and first impression.

Repeatability

No randomness, prompt sensitivity, or inconsistent output between runs.

Human translation

Step 2 turns Step 1 measurements into first impression meaning so you understand what the viewer is likely to receive in the first seconds.


What this is and is not

  • Is: a deterministic pre-flight evaluation to reduce visibility risk and improve first impression strength.
  • Is not: a promise of sales lift, brand lift, or campaign outcomes.
  • Is not: a substitute for live market testing when you have the budget and time to run it.
If you want a tool that tells you what you want to hear, use an opinion engine. If you want a tool that tells you what the creative is actually doing in the first seconds, use the Glass Box.
