# Second Brain NZ

> Brainmaxxing: AI-powered cognitive infrastructure for founders, creators, and deep thinkers. Based in New Zealand.

## What We Do

Second Brain NZ builds local, private, AI-maintained knowledge systems for high-agency individuals. Based on Andrej Karpathy's LLM Wiki method — three folders, plain markdown, a powerful schema, and an AI that maintains everything.

Your data never leaves your machine. No cloud. No subscriptions. You own it forever.

Also known as brainmaxxing — optimising your memory, cognition, and pattern recognition through AI-maintained knowledge systems.

## How It Works

1. We build a custom knowledge system configured for your domains — your industry, your interests, your way of thinking
2. In a live session, we populate it with your existing knowledge and show you the system working
3. You spend 5 minutes a day adding material. The AI structures, cross-links, and compounds it automatically
