How It Works

1

Test Any Page

Add the bookmarklet and interact with any webpage for 90 seconds. Aberio detects behavioral friction and WCAG violations in real-time.

2

Edit & Fix Issues

Review confidence scores in the Monaco code editor. Click highlighted elements to see details. Generate suggestions to reduce noise or edit HTML directly. Save versions as you work.

3

Share & Collaborate

Export the HTML report and share with teammates. They open it in their browser, review your changes, suggest improvements, and add their own edits—all in the same file.

4

Lock Final Artifact

When the team approves, lock the report with a tamper-proof signature. Creates compliance documentation with full audit trail of all changes made.

Built for Team Collaboration

Aberio isn't just a scanner—it's a shared workspace where teams iterate on accessibility fixes together.

Accessibility Teams

  • Test pages and document behavioral findings
  • Generate suggestions to reduce detected noise
  • Share reports with developers showing exactly what needs changing
  • Collaborate on code edits before locking artifacts

Developers & QA

  • Receive reports with code-level fix suggestions
  • Review proposed changes in the Monaco editor
  • Edit code and share updated versions back to the team
  • Track version history of iterative improvements

Advocates & Government Staff

  • Test pages and document behavioral patterns
  • Share findings with leadership and dev teams
  • Create evidence for barrier removal discussions
  • Build locked artifacts with full audit trails for documentation

Important Limitations

Aberio detects behavioral patterns and runs WCAG validations. It cannot replace human testing, certify compliance, or detect all cognitive barriers. Use it to identify issues quickly, then validate with real users and manual testing. Aberio is one tool in your accessibility workflow—not the only one.
