Disclaimer: I am not a lawyer. I am not your lawyer. This is not legal advice.
In the United States, the only patentable subject matter is processes, machines, manufactures, or compositions of matter [1]. Anything outside of those areas is not directly patentable. Some subject matter like mathematics and "mental processes" generally are categorized as "abstract ideas" that therefore are not directly patentable [2]. It is possible to patent something that contains an abstract idea, but it also has to have some "additional elements" that elevate it beyond merely claiming an abstract idea.
I suggest reading MPEP ยง 2106 [2] and looking at the first diagram given there titled "Subject Matter Eligibility Test for Products and Processes". That is the exact analysis that a patent examiner would use to determine if something is patentable subject matter or not (including for any claim with a prompt).
I strongly suggest that you talk to a lawyer if you want specific advice that answers your question directly. I'm not commenting on any copyright aspects.
