Build a personal OS, not a subscription stack.
A personal OS is the foundation that holds the data, knowledge, and context about you, so every tool you put on top stops being generic and starts being yours. It is a second brain that compounds. This page takes you the whole way: what it is, what it is made of, and how to build it yourself.
What a personal OS is made of
Six layers. The same architecture as a Revenue Nervous System, pointed inward. Each one is a building block, and a missing layer turns the rest into chaos instead of leverage. Here is the whole anatomy before you build a single file.
Build from the bottom up. Most people start at the top, at Execution, asking an agent to write something, then wonder why the output is generic. The layers underneath were missing. Start with Data and Context. Everything else compounds on top. Click any layer to jump to how you build it.
How to build it
Two paths. Run the 15-minute bootstrap for a working scaffold right now, or go layer by layer below, where each layer has real templates you can edit and a shortcut prompt that builds it for you.
Start from zero
One bootstrap prompt, four steps, and you have the same scaffold this guide walks through in depth. If you want to understand what you are building, the six layers below unpack every file. If you just want a working system in your hands, stay here.
Your starter kit
Download everything you edited above as a ready-to-unzip directory. Drop it into a new folder. Open CLAUDE.md. Start a session. The system is yours.
