Fill it in one afternoon and you never write a prompt again. Every message the AI produces already knows who you are, what you sell and what you must never say.
The problem
Write a prompt for the campaign. Write another for the reply. Explain your prices again for the reminder. Miss a detail and the message goes out sounding like nobody who works for you. The AI is capable — it just has no idea who you are, because nothing ever told it properly.
What it holds
Do not fancy typing it out? Give it your website and it drafts the whole thing for you to correct.
Guardrails
Anything you write there is carried into every single message as a hard rule — not a suggestion the AI weighs up. If your industry forbids promising returns, or you refuse to claim next-day delivery you cannot always meet, it simply never happens.
Compliance is not a review step you remember to do afterwards. It is part of what the AI is, before it writes a word.
The difference
Then never explain your business to a machine again.
