Many people are saying Gemini 3 is the best AI designer, so I put it to the test. In this video I use Gemini 3 inside Google’s free AI Studio (ai.dev) to design multiple websites and iterate live, so you can judge the quality for yourself.

What you’ll see
– How to build polished landing pages and iterate with short prompts
– Simple tricks to push designs beyond “AI-generated” and make them feel unique
– Exporting code, syncing to GitHub, and where Supabase/auth would fit (overview)
– Three real scenarios: agency site, SaaS landing page with animated UI, local business site
– A creative personal site concept (terminal vibe) and how to make it user-friendly
Why this matters
– Gemini 3’s design choices often feel more “human” and less templated
– Strong default copywriting makes first drafts client-ready faster
– AI Studio lets you keep and own the code (sync to your GitHub)
