A/B Test Architect

Most CRO programs fail not because tests lose - they fail because teams test the wrong things in the wrong order with no clear success criteria. A/B Test Architect gives your AI assistant a complete framework for designing experiments that actually produce learning.

• Prioritizes test ideas using the PIE scoring matrix so you always start with the highest leverage test
• Writes structured hypotheses in the Because / We believe / Will / For / Measured by format
• Calculates estimated sample size and recommended test duration
• Defines primary KPI and guardrail metrics to prevent shipping tests that win on one metric while tanking another
• Guides segmentation decisions - who sees the test, traffic splits, and when to target vs. run full traffic
• Produces complete dev handoff notes including variant descriptions, analytics instrumentation, and results log format
