A strong Synthetic Intelligence brief starts with the business, not the prompt. Name the product, the audience, the offer, the proof, the objection, and what success is supposed to look like.
Those signals give ADNGEN something to reason across. Product benefits affect hooks. Audience intent affects format. Offer strength affects the call to action. Existing media affects what can be produced without inventing assets.
The goal is not to describe every frame manually. The goal is to give the system enough connected context to propose useful campaign directions that you can approve, edit, and generate.
Good briefing creates reusable intelligence. That context can carry into future variants instead of being rebuilt every time.
Keep the context connected so the next campaign can learn from the product, creative, performance, and commerce signals that already exist.
