Everyone is complaining that the web site was made by AI?
Why? It looks like a hundred other web sites. The text isn't different from any other generic sales copy that humans have been doing for ever.
People are so paranoid about AI slop, that they see it everywhere, even if it was just a human. You can't tell.
Just because you personally can't spot it, doesn't mean other people can't. There are a lot of very clear tells of AI writing, and this site is full of them.
