Everyone thinks Perplexity and NotebookLM succeed because they use “better AI.” They don’t. They use the same models as everyone else. I spent three months deconstructing both — not just as a user, but as an architect. I mapped where intelligence lives, traced where humans direct and where AI executes. Here’s what they actually did differently. The answer isn’t in the AI models. It’s in how they architect the flow of work between human and AI. This is what I call Intelligence Flow Architecture — the design of HOW cognitive work flows between human and artificial intelligence. Not what the AI can do, but how the collaboration is structured. Where does intelligence live? Who does what work? How do they hand off tasks?
