KNOW EVERYTHING, DO ANYTHING
WITH NATHAN CAFEARO

Build your first useful calculator
Companion to: You Don’t Need to Know How

STARTING PROMPT
Here is my website: [address]. Suggest a useful calculator for my customers, then build a working first version that matches my branding. Ask me any questions you need to. Use my real prices and assumptions, or clearly label anything still to be confirmed. Show me a preview and help me check a few examples before we consider publishing it.

CHECK YOUR WORK
1. Choose one customer question.
2. Supply real prices, units and assumptions.
3. Test a known answer, zero, a missing field and an unusual value.
4. Review the preview before publishing.
