98% of websites aren't accessible - but there is no silver bullet.
The scope of Page Speaker is twofold:
The first part of the product is the toolbar, which you can easily embed on as many of your web pages as you would like.
Here's a few of the toolbar's unique features:
📊 Unlimited pages and unlimited page views
⚡ Background loading (it doesn't slow down your site)
🔊 Built-in screen reader and many other features, such as "Seizure-safe mode"
But the toolbar alone won't get you to full WCAG compliance.
That's why we created Smart Audits.
This is a system to measure your compliance with seven (and counting) different international web accessibility regulations and technical specifications. It provides actionable insights into how you can improve your pages and make them more accessible right away.
P.S. - Agencies love us, because we uniquely offer multiple websites per license!

I'm looking for either that specific validator (older version of https://validator.w3.org/) or an equivalent that can validate pre-HTML5 (DTD-based) files in a similar fashion. I would appreciate any pointers in the right direction. Thanks in advance. Source: 11 months ago
