You edit before it goes live
The draft is a first pass, nothing more. Change the wording, delete a sentence, fold in a detail the AI could not know. The rule that protects you is simple: an unpublished page is not visible to guests, so a draft link does nothing for anyone until you decide.
This is where honesty matters. The AI will happily write a confident time for a ceremony it was only hinted at. You are the one who knows the hall opens at eleven and lunch is at one. Verify the date, the venue and the guest list — that is human work — and let the drafting carry the rest. Read the whole page once before you publish, because the moment the link goes out it starts collecting replies against the details you confirmed.
