Free kit. Early access.

Andrej Karpathy's free idea, plus the parts nobody gives you.

A second brain you run inside Claude and Obsidian. Everything you read, save, or think lands in one place and comes back when you need it. The idea is free and everywhere. The setup is not. The Brain Kit is the setup.

One email when it's ready. No spam. Heads up: the free kit runs on Claude, which is a paid subscription of about 20 dollars a month. You bring that. Everything else is here.

The real thing, on my real desk. Everything on this page is the system in that clip.

You're on the list. Check your inbox for the kit as soon as it drops. Watch for a message from Braindock.

What you get

The vault, prebuilt

The exact folder structure and Claude router I use every day. You open Obsidian and it already knows where things go. No blank-page paralysis.

The prompt playbook

The exact prompts that run the system: a 2-minute daily check-in, one-paste inbox filing, and asking your own notes questions. This is the part no free template has.

Plain-English setup

Written for someone who has never touched a terminal. Every step in words a human can follow, with a walkthrough you can watch instead of read.

Why not just use the free version

✓The idea (a second brain in Claude) is free. Karpathy said it out loud. That part you already have.
✗A free gist doesn't file your notes for you, doesn't run on your phone, and doesn't hold your hand through setup.
✓The Brain Kit is the folder system, the prompt playbook, and the plain-English setup, packaged so you actually finish setting it up instead of abandoning it like the last template.
Being straight with you: this rides on Claude, a tool that costs about 20 dollars a month and changes often. The Brain Kit is folders, markdown, and simple routing, so it is not locked to any one app. If the tool changes, the system moves with you.
