Digital Web Accessibility Widget - Only those who have the source code OR have been working on this kind of project

We are interested in getting in touch with those developers/companies who have built Digital Web Accessibility Widget and have the source code OR have been working on this kind of project.
We are interested in having our own "Digital Web Accessibility Widget" with AI to make our client's website accessible to users with disabilities.
It should be like: userway.org or Accessible360.com or EqualWeb.com or audioeye.com or accessiBe.com
