Y Combinator's Design Review hosts Magic Patterns (W23) founder Alex Danilowicz, who demos the prompt-to-prototype tool and its new MagicOS canvas for combining prompts, images, PRDs and other context. The episode also reviews four startup websites (Ego, Sentient OS, Cerenovus, Slashy) to break down why AI-generated designs feel 'vibe coded', how to get better results from AI design tools, and why everyone at the company talks to users.
