Plain language is an important part of making things accessible for disabled people. Plain language works because disabled people are part of writing it. Disabled people use our lived experience to make sure plain language is accessible. ASAN wrote a statement to tell people we do not need artificial intelligence to do this work when we know disabled people do it best. We tested artificial intelligence programs by telling them to write in plain language, and they made big mistakes that prove they should not be used to make writing accessible.
