One of the biggest names in the field is accessiBe, an AI-powered web accessibility tool that can ensure your website meets a range of accessibility standards, including WCAG 2.1, ADA and Section 508. It's got a 2-minute installation process, automated accessibility statements and certifications, and it can help you reach a broader audience while avoiding legal problems. That makes it a good option for businesses that want to improve accessibility without a lot of hassle.
Another is Eye-Able, a collection of AI-powered tools to build accessible websites. Among its abilities are tools to simplify text on the fly, translate content automatically and check for WCAG compliance. Eye-Able is geared in particular for people with vision impairments and cognitive disabilities, and it can be set up to integrate assistive technology so people can customize their experience. That could be useful for people with dyslexia or other reading challenges, too.
If you want to personalize your website's display for different impairments but don't want to worry about code, FACIL'iti is worth a look. It's got more than 1,200 customizable features to address visual, motor and cognitive disabilities, so it can help people with low vision, dyslexia and other conditions. FACIL'iti doesn't share user data and doesn't require you to change your website, so it's a good option if you want to improve accessibility without a lot of hassle.
