Today we're introducing our new Chrome extension, made to help you spot accessibility issues and fix them while you browse the web.

Rocket Validator A11y Panel brings [AccessLint](https://rocketvalidator.com/accesslint) checks straight into your browser. It's **completely free**, and you **don't need a Rocket Validator account** to use it.

## How to install the extension from the Chrome Web Store

The [Rocket Validator A11y Panel extension](https://chromewebstore.google.com/detail/gahibfmnpgepdpoenddkcnagncndbddh?utm_source=item-share-cb) is available on the Chrome Web Store.

Press **Add to Chrome**, then pin the icon to your toolbar to keep it within reach.

## What's inside the accessibility panel

The panel always shows the results for the current tab, and they update as you move through the site. Every check **runs locally**, in your own browser, and **nothing gets sent to Rocket Validator**. So it also works against your local web server, or on password-protected sites.

Inside the panel you'll find the accessibility issues, **grouped by topic**. Each one comes with a short explanation of why it matters, a link to the extended guide, and tools to locate the element: **Highlight** outlines it on the page, and **Copy Selector** gives you its CSS selector.

Finally, the **AI Prompt** button writes out the technical details of the issue, ready to paste into your favourite AI so it can explain the problem and fix it for you.

## See it in action

We recorded a short walkthrough of the install, and of the panel working on a real page.
