Not a black box. Every score has a source. Every fix recovers a conversion.
We measure the experience; the result is conversion. Corexi gives you the score, the research it comes from, the evidence behind it, and the code to fix the friction costing you users.
One number. Five dimensions. Tied to conversion.
Your UX Score is a weighted composite of five dimensions, derived from 9 evaluation categories. Each maps to conversion impact — behavioral health captures drop-off, visual quality captures first impressions, accessibility captures the users you never reach. The formula is public, not hidden.
Multi-viewport: desktop carries 60%, mobile 40%. Each scan accumulates product context, so scores get sharper over time.
9 core categories
Every page scan is evaluated across these categories. Each has measurable criteria rooted in 200+ peer-reviewed sources, and each maps to the friction that quietly costs conversions. Every accessibility finding is cross-checked against axe-core.
Visual Hierarchy
Is the most important element the first to catch attention? Are headings differentiated? Is the flow logical?
CTA Visibility
Can you find the primary action in under 2 seconds? Is contrast above WCAG AA 4.5:1? Is sizing right?
Form Design
Are labels present and readable? Are error states designed? Are inputs sized for touch and keyboard?
Spacing & Layout
Is white space consistent? Is a grid present? Are there cramped or scattered areas?
Typography
Are fonts readable at 16px+ body? Is line length 45–75 characters? Does weight create hierarchy?
Color & Contrast
Does text pass WCAG AA? Is the palette consistent? Is color ever the sole information carrier?
Mobile Responsiveness
Are touch targets 44×44px+? Is there horizontal scroll? Is text readable on a phone?
Cognitive Load
Can a first-time user understand what to do? Is navigation clear? Is there decision paralysis?
Accessibility
Alt text, form labels, keyboard nav, ARIA, focus indicators. Every claim axe-core verified.
+5 neurodiversity dimensions
WCAG covers compliance. It doesn't cover whether a neurodivergent user can actually complete a conversion. 15–20% of users think differently, and every one of them is a conversion. No other automated tool measures this.
ADHD Friendliness
Visual clutter, animation control, content chunking, clear next-step CTAs.
Dyslexia Readability
Line length, letter spacing, justified text, ALL-CAPS blocks, contrast below 7:1.
Autism Predictability
Consistent navigation, predictable layouts, clear labeling, minimal unexpected changes.
Sensory Sensitivity
Animation intensity, auto-playing media, contrast extremes, visual overwhelm indicators.
Color Vision Deficiency
Red/green combinations, color as sole info carrier, problematic color pairs.
Your analytics + our snippet. One confidence score.
Visual analysis tells you what looks wrong. Behavioral data tells you what actually costs conversions. Connect your analytics or drop our one-line snippet. The more sources you connect, the sharper the diagnosis.
Verified, not guessed.
Every accessibility finding is cross-checked against axe-core at runtime. Verified findings carry a badge; LLM-only findings stay flagged. You always know which is which.
Verified finding
AI detected an issue AND axe-core confirmed it against WCAG 2.2 rules. 27 rule IDs checked. The standard for compliance claims.
AI-only finding
AI detected a potential issue but no deterministic rule confirmed it. Flagged for human review. Transparent about confidence.
Three layers. One score.
Every scan flows through three analysis layers. Each adds a different kind of evidence. Together they produce findings no single layer could generate alone.
Visual layer
Multi-viewport screenshots analyzed by AI vision across all 9 categories. Deterministic checks (contrast, touch targets, spacing) run alongside AI interpretation. This is what you see.
Behavioral layer
Real user signals from your connected analytics and the Corexi Snippet: bounce rates, rage clicks, scroll depth, form abandonment. The exact moments users give up on converting.
Reasoning engine
Cross-validates visual findings with behavioral data. A contrast issue that correlates with high bounce scores higher than one with no behavioral signal. Ties every finding to conversion impact — and gets sharper with every scan.
Visual-only scans work from day one. Adding behavioral sources lifts confidence from ~40% to 85%+. The engine adapts to what you connect.
Privacy-first. Always.
Minimal, opt-in tracking
The Corexi Snippet is optional and cookieless. Anonymous behavioral signals only — no PII, no session replay, 24h retention. Your users see nothing.
Read-only analytics
We connect to your existing providers via read-only API. We pull aggregated metrics only.
No PII, ever
Bounce rates, session depth, engagement patterns. Never individual identities, emails, or browsing histories.
EU-based, GDPR compliant
All processing on EU infrastructure. Credentials encrypted at rest (AES-256). Disconnect and delete any time.
