Please produce:
1. A one-paragraph campaign summary
2. 3 creative territories (different emotional or rational angles to explore)
3. For each territory: headline, visual direction, and copy approach
4. Suggested A/B test structure for the first two weeks Why this works
The single key message requirement is the most important constraint in this brief — forcing one message prevents the creative team from trying to say everything and saying nothing. Separating campaign goal from CTA ensures the brief distinguishes between awareness intent and conversion intent, which drive completely different creative approaches. Including audience mindset (not just demographics) gives creative teams the emotional context they actually need.
Risks & review
The AI will produce a structurally strong brief but the audience insight and key message must come from real customer knowledge and research — AI-generated audience assumptions produce generic creative. The brief should be reviewed by someone who has actually spoken to the target customer before being handed to a creative team.
