Building a Personal AI Infrastructure (PAI) (December 2025 Version)

So the umbrella of everything I'm gonna talk about today is what I call a Personal AI Infrastructure (PAI), which is PAI for an acronym. Everyone likes pie. It's also one syllable, which I think is an advantage. But here's what makes PAI v2 different from what came before: This isn't just a collection of prompts and tools anymore. PAI v2 is about taking Claude Code—which is already incredible—and personalizing it into YOUR cognitive operating system.

Think of Claude Code as the foundation, like macOS or Linux. It's powerful out of the box. But PAI v2 is about customizing that foundation so deeply that it becomes an extension of how YOU think, work, and create.
