Your Second Brain in 60 Seconds

Andrej Karpathy — the AI researcher behind Tesla Autopilot and OpenAI — shared a deceptively simple idea: the best personal knowledge management system is just three folders and a schema file.

The Problem with Every PKM System

Notion, Obsidian, Roam, Evernote — they all share the same fatal flaw. They require you to organize. They assume you'll tag, link, categorize, and maintain a system. You won't. Nobody does. Not consistently, not long-term.

The result? A graveyard of abandoned wikis and half-tagged notes. Your knowledge sits there, inert, instead of compounding.

Three Folders. That's It.

The Karpathy method strips it down to the minimum viable system:

• raw/Dump everything here. Notes, docs, bookmarks, screenshots. Don't organize — just dump.
• wiki/AI compiles your knowledge into structured, searchable wiki pages. Built automatically from your raw data.
• outputs/Ask questions, generate reports, make connections. Your knowledge compounds over time.

The Secret: CLAUDE.md

The difference between a messy wiki and a compounding knowledge asset is the schema file. CLAUDE.md tells AI how yourbrain works — your domains, your categories, your connections. It's the blueprint that makes the system personal.

Without it, you get generic summaries. With it, you get a second brain that thinks like you do.

Why Brainery Exists

Building your own CLAUDE.md is possible. But getting it right — tailoring the schema to your role, your domain, and your thinking style — takes expertise. That's what we do.

We build your CLAUDE.md, migrate your data, deliver a working wiki, and keep it compounding with monthly health checks. You get the system without the setup pain.
