How to build SaaS App in a weekend using AI (Steal This)

Synopsis

Greg walks through a step-by-step weekend SaaS build using AI: pick the niche audience first, research competitors with Gemini, grill the idea with Claude for honest feedback, draft a one-page PRD, break UI into shippable chunks, generate screens in V0.dev, then wire the backend. He emphasises solving real pain, not aesthetics, and frames the whole process as a Reddit-post methodology anyone can replicate.
