Lente Scan is a web service that performs automated accessibility diagnostics based on WCAG 2.2 Level A and AA standards. Simply enter the URL of the webpage you want to diagnose, and you can view the diagnostic results and detailed explanations of issues—all for free, without requiring account registration.
In addition to the open-source auditing engine "axe-core," we have integrated "Lente Detect," developed in-house by Liberogic. It detects approximately 30 additional items for which axe-core lacks rules—including landmark structure, semantic table markup, and ARIA attribute consistency.
We also leverage insights from IAAP-certified WAS (Web Accessibility Specialist) holders to clearly present the impact that detected issues have on users, along with guidance on remediation direction.
Areas that require manual review—such as alt text quality, keyboard navigation, and reading order—are clearly marked as "regions requiring manual diagnosis" since automated testing alone cannot assess them. This design helps teams understand not only the automated test results but also the specific points that need human review next, ensuring they don't rely solely on automated checks to determine conformance.

Please note that automated diagnostic results do not constitute proof that a website is compliant with WCAG or JIS X 8341-3. Accurate conformance assessment requires manual diagnosis by specialists and verification by actual users.
