PM Prototyping

A PM's guide to building working prototypes with AI

Replace the PRD with a behavioral brief, generate an interactive prototype, iterate in the same environment, then hand engineering a tested prototype.

6 steps

  1. Pick one user need and hypothesis
  2. Write a behavioral brief for the AI instead of a PRD
  3. Generate a first prototype and review direction, not pixels
  4. Iterate on layout, flow, states and edge cases in the same session
  5. Share for early feedback
  6. Hand engineering a working, tested prototype
