Developing the prompt that powers the business advisor required 3 months of iterative testing with entrepreneurs and local experts (including RMI lab member Brian from Kenya) to refine tone, vocabulary (removing Harvard jargon), and contextual appropriateness. The prompt works by instructing the AI to 'use simple, non-technical English' and 'avoid discussing health, religion, politics, or current events.' This demonstrates that effective AI tool design for emerging markets is fundamentally a writing/humanistic problem, not a coding problem.
