Getting Started

Step 1: Install the extension

Install from the Chrome Web Store or Edge Add-ons. The A11y Lens icon will appear in your browser toolbar.

Step 2: Run your first scan

Navigate to any web page, then click the A11y Lens icon or press Alt+Shift+A to open the Side Panel. Click "Scan Page" to analyze the page for accessibility issues.

Step 3: Activate Pro (optional)

After purchasing Pro, you'll receive a license key via email. Open A11y Lens, go to Settings, and paste your license key to unlock unlimited scans and PDF/HTML exports.

Step 4: Export reports

With Pro activated, click "Export" after any scan to generate a custom professional HTML or PDF report. Share these reports with your team, clients, or stakeholders.

Frequently Asked Questions

How does the freemium model work?

You get 10 free scans per month. The counter resets automatically. Upgrade to Pro ($12/month or $99/year) for unlimited scans and exports to share with your team or stakeholders.

What's included in the exported reports?

Reports include all violation details, WCAG success criteria references, severity classifications, code snippets, and remediation instructions—formatted in clean HTML or PDF ready to share. Pro users can add custom branding (company name, logo) and element screenshots.

Does A11y Lens catch all accessibility issues?

No automated tool catches everything. A11y Lens finds common WCAG violations, but manual testing is still needed for complete accessibility coverage—especially for keyboard navigation, screen reader compatibility, and contextual issues.

Is my data collected or sent to a server?

No. A11y Lens runs entirely in your browser. Scans happen locally, and no data is sent to external servers. All reports are generated on your machine. Your privacy is protected.
