What is cognitive accessibility?
It is the accessibility of content, structure and journeys for people who may experience barriers with attention, memory, language, processing, fatigue or information overload.
AXS AUDIT GUIDE
Cognitive Accessibility Checker
A cognitive accessibility checker looks beyond whether a page technically passes a rule. It asks whether people can understand, process and complete tasks without unnecessary cognitive load.
This is where AXS Audit is most distinctive: Cognitive Accessibility Score, Cognitive Load Index and audience-impact mapping for users such as people with dyslexia, ADHD, autism or low literacy.

Direct answer
Cognitive accessibility checking measures friction, not just failures
Cognitive accessibility is about clarity, load, attention, support, distractions, personalisation and how understandable a journey feels in practice.
AXS Audit brings this into the scan result through proprietary cognitive metrics that sit alongside WCAG checking.

|---|---|---|
| What does it check? | Cognitive friction. | A technically valid page can still be confusing, distracting or hard to complete. |
