Because the interface design of many text generators is meant to mimic a conversation with another person, people will often describe their interactions as "having a conversation with" or "asking" these tools.
But I do not "ask" autocorrect when I am typing and it prompts me with possible phrases, even if what I typed before ends in a question mark.
That is what these tools are doing: providing possible endings or continuations of what came before. They are text generators generating text.
