Give it a rough idea, get back a ready-to-post caption built on a real hook and mood, not a generic paraphrase.
This writes a rough first draft from what you tell it. It doesn't know your business beyond what you type, so check names, dates, and prices before you post. It flags a few high-risk situations, a minor shown by name, a guaranteed-result claim, or content it won't write at all, but it's not a substitute for your own judgment. Nothing you enter is saved between requests.
