We Built an Accessibility Engine That Actually Fixes the Web

Most accessibility overlays are just theme switchers. A11yCore is different—it's a remediation engine that mechanically repairs inaccessible websites in real-time. Now available as a free Chrome Extension.

We Built an Accessibility Engine That Actually Fixes the Web

Here's the uncomfortable truth about most accessibility overlays: they're glorified theme switchers.

They let you change font size. Invert colors. Maybe adjust contrast. But they don't fix the actual code. They don't make a broken form work for keyboard users. They don't tell screen readers what a "Click Here" button actually does.

The accessibility community has been rightfully skeptical of these solutions for years. We didn't want to build another one.

So we built something different.


From Theme Switcher to Repair Engine

A11yCore isn't a widget that sits on top of broken code. It's a remediation engine that repairs accessibility barriers at the DOM level—dynamically, in real-time, as you browse.

We've been licensing this technology to enterprises who want to permanently fix their websites for every visitor. But we realized something: waiting for every company to upgrade takes time. And you shouldn't have to wait.

So we're releasing our entire enterprise-grade remediation engine as a free Chrome Extension.


8 Things Most Overlays Can't Do (But A11yCore Can)

Here's what happens when our engine runs on a page:

The Problem:A "Read More" link with no context. Screen reader users have no idea where it goes.

The Fix:Our engine scans the DOM context—surrounding text, parent containers, destination URL—and dynamically injects a descriptive aria-label. Suddenly, "Read More" becomes "Read More about accessibility standards."

2. Prevents Seizures (Pixel-Level Analysis)

The Problem:Videos that flash rapidly (more than 3 times per second) can trigger photosensitive epilepsy.

The Fix:The plugin uses an off-screen HTML5 Canvas to analyze video frames in real-time. When it detects unsafe luminance changes or red flashes, it automatically applies CSS dampening filters—keeping users safe before their eyes reach the dangerous content.

3. Defeats Dark Patterns & Cognitive Traps

The Problem:Sites use false urgency ("Only 2 minutes left!") or confusing double-negatives ("Uncheck to not unsubscribe") to manipulate users. This is devastating for people with cognitive disabilities.

The Fix:Our DeceptionDetector scans for manipulation patterns and highlights them with warning badges. It flags hidden costs buried in fine print and pre-checked boxes with financial implications.

4. Stabilizes Mobile Layouts

The Problem:Zooming in on mobile sites often breaks the layout, forcing horizontal scrolling to read text (a WCAG Reflow failure).

The Fix:We don't just change font size. The engine enforces proper overflow handling and word-breaking at the container level, forcing content to reflow correctly even at 200% zoom.

5. Keeps You Logged In (Heartbeat Simulation)

The Problem:Short session timeouts log out users with motor disabilities who take longer to interact, causing them to lose all their work.

The Fix:Our TimeoutAssist module detects session timers and can simulate user activity to keep sessions alive. It intercepts timeout modals to give you clear, accessible options to extend your time.

6. Makes Touch Gestures Keyboard Accessible

The Problem:Carousels, maps, and sliders often rely on swipe gestures that are invisible to keyboard users.

The Fix:The plugin detects gesture libraries (like Hammer.js) and injects alternative controls, mapping arrow keys and shortcuts to gesture actions. Instantly keyboard-accessible.

7. Real AI Alt Text (Visual Language Models)

The Problem:Missing alt text results in "Image 123.jpg" being read aloud—completely useless.

The Fix:We use vision-language models to analyze image content and generate descriptions with confidence scores. High confidence? We inject it. Low confidence? We flag it for review.

8. Bypasses Paste Blocking

The Problem:Forms that block password pasting force manual typing—a barrier for users with cognitive impairments who rely on password managers.

The Fix:Our AuthAssist module overrides these restrictive event listeners, re-enabling paste on all password fields. Authentication becomes frictionless.


This Isn't a Different Way to View the Web. It's a Way to Repair It.

When you install the A11yCore extension, you're carrying a remediation engine with you everywhere you browse.

You can land on a completely broken, inaccessible website, and with one click, our engine will:

• Inject the necessary ARIA labels • Fix focus traps • Stabilize broken layouts • Generate missing alt text • Make gesture-only interfaces keyboard accessible

This is mechanical remediation, not cosmetic preference.


Why We're Releasing It for Free

Our primary business is licensing this engine to enterprises as a SaaS platform—helping them fix their code permanently for every visitor.

But relying solely on site owners to upgrade their accessibility takes time. And we realized:

You shouldn't have to wait for the rest of the web to catch up.

So we decided to put this power directly in your hands.


Coming Very Soon

The A11yCore Chrome Extension is currently under review by the Chrome Web Store and will be live within days.

If you've been frustrated by inaccessible websites, or if you're someone who believes the web should work for everyone—this is for you.

Follow A11yCore for the download link announcement, and feel free to share this with anyone who might benefit.

The web is broken. Let's carry the fix with us.
