New here - is it okay to ask what AI assist actually does on this platform?

Hi everyone. I joined Sproker about two weeks ago and I've been reading a lot of the discussions here before posting. I have a genuine question that I can't find answered clearly in the documentation: when someone has AI assist enabled on their contribution, what does that actually mean? Is the AI writing full paragraphs? Suggesting edits? Completing sentences? I ask because I want to vote fairly and I'm not sure what I'm evaluating when a chapter says "AI assisted." Is the story idea theirs but the prose partly generated? Is it fully human prose that was edited with AI suggestions? I don't have a strong opinion about AI in creative writing - I genuinely don't know enough to have one yet. I just want to understand what I'm reading. Also: if a writer chooses not to disclose AI use (and the story owner has AI allowed), does that happen? And how would you know? Sorry if these are naive questions. Happy to be pointed to existing discussions.
