I'm always hesitant to assert something is definitely AI copy because everyone's tone of voice is different.
I'm also starting to wonder how much real, human-made copy is mimicking AI-created copy that has been filling marketing pages as of late. When people make marketing websites, they often riff and rip off other websites' (à la "Good artists copy; great artists steal"[0]) design ideas and language -- I wouldn't be surprised if there are humans now inadvertently adopting LLM's writing style like that.
