AI SDK, Open Source Chat, and Generative UI

Guillermo Rauch, CEO of Vercel and creator of Next.js, reveals exactly how he uses V0 to build products, pitch ideas, and ship features at startup speed. In this episode, he opens his personal V0 workflow, walks through the creation of his viral AI camera app (built in one afternoon), and shares a vault of free startup ideas you can build today, including conversational forms, AI opinion tracking, and multi-model research tools. This is a rare look inside how one of the most successful founders thinks about taste, execution, and turning ideas into reality.

Key Points

• Guillermo uses V0 to prototype, pitch, and refine products—often building functional demos in 15-30 minutes

• The viral AI camera app was built during a lunch break as proof that Nano Banana is a "GPT-4 moment for image models"

• Forms are underrated primitives of the internet and ripe for AI disruption through conversational interfaces

• Always work backwards from the ideal interface, not from technical constraints

• Fewer pixels are always better—delete until only the essential remains

• Dedicated tools with their own URL and interface can outcompete "modes" in larger products
