The AI pushes you to clarify what you really do, for whom, and especially why it's different. The prompt below is designed to extract key information from you and transform it into a comprehensive strategic positioning, including your unique value proposition, brand territory, and key messages. Whether you're launching a new product, repositioning an existing offer, or seeking to differentiate in a saturated market, this prompt guides you step by step toward a memorable and defensible positioning.
