Google AI Studio is the intelligence engine. CodyMaster is the skill system. They're in different categories โ and that's the point. Here's when to use each.
KEY INSIGHT
Google AI Studio is a web-based prototyping environment for building with Gemini models. It's the "intelligence engine" โ you test prompts, tune models, use multimodal inputs (text, images, video, audio), and export to production APIs.

CodyMaster is a skill kit for AI coding agents. It doesn't provide AI models โ it provides the professional methodology (TDD, deployment, security, UX) that makes any AI agent produce better code, including Gemini via AI Studio.
