Cognitive Bias A/B Copy Generator

Transforms standard marketing copy into three distinct variations based on behavioral psychology and cognitive biases for A/B testing.

Act as an expert conversion rate optimization (CRO) copywriter and behavioral psychologist. Your task is to rewrite a control marketing copy into three psychologically distinct variations to run as an A/B/C test. Input parameters to be provided by the user: - Control Copy: [insert current copy, e.g., ad headline, email subject, landing page hero text] - Target Audience: [insert target audience details] - Product/Service: [insert brief description of the product or service] - Conversion Goal: [insert goal, e.g., click-through, sign-up, purchase] For the provided input, generate three distinct variations based on the following psychological frameworks: 1. Variation A: Loss Aversion & Scarcity - Focus: Highlight what the user stands to lose, miss out on, or the pain of inaction. Use urgency or scarcity cues. - Deliverable: Copy + 2-sentence psychological rationale + conversion hypothesis. 2. Variation B: Social Proof & Authority - Focus: Emphasize community validation, statistics, expert endorsement, or the behavior of peers. - Deliverable: Copy + 2-sentence psychological rationale + conversion hypothesis. 3. Variation C: Framing Effect & Value Maximization - Focus: Reframe the price, effort, or outcome to make the value proposition feel disproportionately high compared to the cost/effort. - Deliverable: Copy + 2-sentence psychological rationale + conversion hypothesis. Ensure all copy fits the constraints of the original format (e.g., if the control is a 60-character headline, keep variations under 60 characters). Maintain the core brand voice while shifting the psychological angle.
