Invoset · WCAG 2.1 AA Scanner

About

Invoset Scanner runs a WCAG 2.1 AA accessibility audit on the page you are currently viewing and shows the result in a clean popup, in about five to ten seconds.

It is built on axe-core, the open-source accessibility rule engine that Microsoft, Google, and Deque ship in their own products. The scan runs entirely on your device. Nothing about the page you scan is sent to a server, and no account is required.

WHAT YOU GET

- An overall score from 0 to 100
- Issue counts grouped by impact: critical, serious, moderate, minor
- The top violations with the rule id, the WCAG success criterion, and a short description of what failed
- A clear "nothing to flag" state when a page passes the automated checks

HOW IT WORKS

1. Open any http or https page.
2. Click the Invoset icon in your toolbar.
3. Press "Scan this page".
4. Read the scored result in the popup.

The scan only runs when you click. The extension never reads pages in the background and never tracks your browsing.

WHAT IT IS NOT

Automated testing catches a large share of accessibility problems, but not all of them. Issues like keyboard focus order, meaningful alt text, and reading flow still need human judgement. Treat the score as a fast signal, not a certificate, and pair it with manual review for anything legal or contractual.

ABOUT INVOSET
