Why Aberio Report?
Find What Others Miss
Traditional scanners only check code. Aberio instruments show you where behavioral noise occurs during actual user interactions. You find potential barriers through patterns like keyboard gravity, focus struggles, and unexpected page changes.
Get Data You Need
Generate comprehensive reports with objective, scientific data. Our confidence scoring maps directly to ADA "readily accessible" principles, giving you the evidence you need to push for change.
Test Fast, Test Thoroughly
Complete page testing in 90 seconds. Automated heat maps highlight problem areas. Generated .js files include confidence scores that project where improvements may be needed based on behavioral noise patterns.
Privacy-First, Always
All testing happens locally in your browser. No data collection. No external servers. No vendor lock-in. Your testing data stays yours.
Future-Proof Methodology
Aligned with WCAG 3.0 confidence methodologies and ADA Subpart H effective communication principles. Aberio shows where noise and confidence scores drop, indicating where users may experience barriers—helping you understand potential usability, readability, and functional accessibility issues.
Made for Advocacy
Export .js files to share with developers and stakeholders. Collect behavioral noise metrics that indicate potential barriers to effective communication. Create artifacts IT can understand and use to guide remediation efforts.

See Aberio In Action
From detection to fix script generation—here's how Aberio turns behavioral noise into actionable accessibility improvements in 90 seconds.
Step 1
Listen to Behavioral Noise
Aberio captures real-time user interaction patterns as you navigate the page, detecting behavioral noise across 6 signal types: WCAG violations, system noise (unexpected changes), keyboard gravity (navigation struggles), pointer gravity (click issues), ungated navigation (unexpected page changes), and keyboard activation problems.
Step 2
Review Test Report
After the 90-second test completes, Aberio processes results and opens a dialog showing your comprehensive test report with confidence scores and detected barriers. Review the findings and download the report, then click 'Continue to Results' to select issues to fix.
Step 3
Select Components to Fix
Review detected barriers with confidence scores. Select components for the Script Builder to generate targeted accessibility fixes with detailed implementation guidance.
Step 4
Add Context & Generate Fixes
Aberio asks for missing information (like alt text or button labels) through a simple wizard, then generates a .js fix script your developers can review and apply. You can even test fixes live using retest mode to compare before/after results.
Step 5
Share With Your Team
Download the .js report file and share it with your development team and stakeholders. Each report includes WCAG references, confidence scores, and implementation guidance for the team to review and address.
What Aberio Can't Do
Aberio is a powerful tool, but it's not a complete accessibility solution. Here's what you need to know:
Cannot Replace Human Testing
Aberio detects behavioral patterns that suggest barriers, but it cannot replace testing with real disabled users. Automated tools—including Aberio—miss context, cultural factors, and nuanced experiences only humans can provide. Always validate findings with actual disabled testers.
Not a Compliance Certification Tool
Aberio helps you identify barriers and gather evidence, but it doesn't certify compliance. Legal compliance requires comprehensive auditing, manual testing, assistive technology validation, and expert review. Use Aberio as one tool in your accessibility toolkit, not the only one.
Limited Cognitive Accessibility Coverage
Aberio focuses on interaction barriers and perceivable issues (keyboard navigation, focus management, contrast, etc.). It has limited ability to detect cognitive barriers like complex language, confusing layouts, or overwhelming information density. Cognitive accessibility requires human judgment and user testing.
One Tool Among Many
A robust accessibility workflow includes screen reader testing, keyboard testing, automated scanners, manual code review, user research, and Aberio. No single tool finds everything. Use Aberio alongside other methods for comprehensive accessibility.
The Right Way to Use Aberio
Use Aberio to find potential barriers quickly, then validate with real users, manual testing, and expert review. Think of Aberio as a flashlight that highlights problem areas—but you still need to inspect those areas carefully with other tools and human insight.
