Reviewing Claude Opus 4.5
The Startup Ideas Podcast
Anti-Gravity Workflow with Nano Banana
They test Anti-Gravity; it generates Nano Banana mockups and shows integrated high-fidelity visuals.
I sat down with James, the Boring Marketer, to stress-test Claude 4.5 Opus against Gemini 3 Pro for real-world coding and design work. Together we live-build and compare landing pages and clickable prototypes for an “EstateClear” probate-family dashboard, then zoom out into conversion copywriting frameworks, “elevated direct response” brand voice, and ad creative workflows. The episode is a practical walkthrough of how non-technical builders can go from idea → landing page → prototype → ads using modern AI tools without vibe-coded, low-converting sites.

Key Points
Claude 4.5 Opus can act like a senior engineer for non-technical builders when paired with a tight skill and tools setup.
Conversion wins come more from “elevated direct response” copy and clear page architecture than from fancy visuals alone.
Claude’s front-end design skill meaningfully reduces “AI-looking” gradients and vibe-coded layouts, producing cleaner, production-grade UIs.
Live tests show Opus 4.5 generates more refined layouts and deeper product thinking, while Gemini often injects clever AI product features.
Google’s integration of Anti-Gravity, Nano Banana, and AI Studio points to a powerful end-to-end environment for shipping and promoting products.
