AI-generated content is an extension of article spinning. The two significant plays in the content space right now are AnyWord and Copy.AI. When you look at these sites, you can see that they're practically the same. They offer the same service, with the same sort of disclaimers and example use cases, for things like ad copy, landing pages, SMS marketing, and so on. Heck, you can even see signs that they've rushed to be the first to market; the Copy.AI team photos are just screen captures of a Zoom call, and so is Anyword's, just in their About section.
