I Tested Gemini 3 as a Designer. It’s Terrifyingly Good.

Greg Isenberg tests the UI/UX design capabilities of Gemini 3.0 via Google AI Studio. He demonstrates 'vibe designing' by prompting Gemini to redesign his personal website, build an AI analytics dashboard for restaurants, and create a gamified fitness app called 'Gains'. During the demonstration, he pitches IdeaBrowser as the ideal source for startup ideas and PRDs to feed into these AI design tools.
