Make it feel like a real internal tool - professional, efficient, solves a clear pain point. Something a team of 10-50 people would actually use daily. One person. Zero dollars. 72 hours. A real business tool built entirely with AI.

In this video I document the full process of building ExpenseFlow — an expense submission and approval system for small teams — using nothing but AI tools and no-code. No developers. No agency. No CS degree.
But this isn't just a build video. Stick around to the end because what this experiment revealed about AI, opportunity, and your generation is something nobody is talking about honestly.
