Nine questions.
No email required.

This measures three things: whether you have decided what your work is, whether anyone outside your head can repeat it, and whether it survives the next thing you add. Nothing is stored anywhere but your own browser.

Answer honestly rather than aspirationally. A flattering score is no use to either of us.

Nine questions cannot see your market, your pricing or what the people who know your work would say without you in the room. Treat this as a starting point for a conversation, not a verdict.
