What AInspector for WCAG Evaluation is

AInspector for WCAG Evaluation is a free browser extension for examining web accessibility. It evaluates WCAG 2.0, 2.1, and 2.2 Level A and AA requirements, along with ARIA specifications. Automated scans produce pass-or-fail results organized by rule categories and WCAG guidelines. The extension also identifies rules that cannot be evaluated programmatically, directing users to perform manual checks. Results can be exported in CSV or JSON, and remediation guidance supports follow-up work. AInspector lists Chrome, Edge, Firefox, and Opera, and also runs on Brave and Vivaldi. Version 4 provides a side panel in Chrome, Edge, and Opera. The Chrome listing says no login is required and that the extension does not collect user or evaluation information. AInspector is licensed under the Mozilla Public License 2.0, allowing free use, copying, and modification. The OpenA11y Evaluation Library is also open source under that license. The project began within the Accessible IT Group at the University of Illinois Urbana-Champaign, with Jon Gunderson continuing development through OpenA11y.
