From Customer Interview to Working Prototype in One Afternoon (AI-Powered Product Building)

Piotr Kacala & Wojtek Strzalkowski
AI Product Heroes & GOG.com
Abstract

Most discovery processes optimize for documentation, not learning. We’ll show a different approach: the Superhero Formula applied with AI tooling. Live demo of interview transcription and analysis, insight synthesis in Miro AI, and rapid prototyping via Lovable. The goal isn’t speed—it’s building the judgment to know when the output is garbage and when it’s gold.
