The AI second brain

A living wiki that gets smarter every run

It reads everything you've ever made and compiles it into a living wiki — one page per topic, in Karpathy's method. Every time an agent runs it writes back into the wiki first, then hands you an idea. So the brain gets a little smarter every single time. New topic? It opens a new page on its own. The wiki never stops growing.

The living wiki

Karpathy's method · one page per topic

The whole system rests on one idea: instead of a pile of chats and files, you keep a wiki. Every note you've ever written, every build, every conversation gets read across and folded into topic pages.

Raw history is messy and forgettable. A wiki is not. The system distils everything down to what matters and files it under the right topic, so a thought from a session eighteen months ago sits on the same page as the note you wrote yesterday. When something doesn't fit an existing page, it opens a new one — no one has to curate it by hand.

The write-back loop

read → learn → write back → hand you a thought

This is the part that makes it a brain and not a search box. An agent doesn't just answer and vanish — it updates the wiki before it talks to you.

Read across the wiki — the agent pulls the pages relevant to its angle.
Write back first — it records what it learned into the right page, opening a new one if the topic is new.
Then hand you a thought — only now does it surface an idea, backed by everything it just filed.
Repeat every six hours — so the next run starts from a slightly smarter brain than the last.
CadenceEvery six hours the agents update the wiki, then write you something new — in the journal, while you sleep. You wake up to fresh thinking.

One agent, four angles

Hermes · Post · Build · Stoic · Note

Four Hermes agents run against the same wiki and the same data — your articles, your chats, your sessions — but each looks at you from a different angle. Together they cover the money, the making, the mind, and the writing.

A1Post

Reads your old articles and builds, and finds what actually made money — with live proof pulled from the web.

→ the play worth repeating
A2Build

Looks at what you've built but never shipped, then tells you exactly what to make next.

→ the next thing to ship
A3Stoic

Reads your journal and your own psychology profile, and coaches you through the day — calm and consistent.

→ the mindset you keep losing
A4Note

Studies your best Substack notes and hands you the next one to write, checked against what solves a real problem.

→ the next note, backlogged
A1

Post — find what made money

Post reads across your articles and builds and looks for the pattern that actually converted. It doesn't guess: it cross-checks against live web research and your own numbers, so the play it hands you comes with proof attached rather than a hunch.

You repeat what worked instead of re-discovering it by accident.
A2

Build — what to ship next

Build mines your Claude Code sessions for the things you made but never published, then points at the one worth finishing. In one run it pulled ideas scraped from sessions you'd long forgotten, spun up a fresh SEO page, and tied the suggestion back to an old project — cloning a site that had generated $50K — with the money proof already stapled on.

Under that suggestion sits an SEO Agent — Ideas link: the raw builds scraped from past conversations, cross-checked against your article data. It even read your post statistics and flagged that one earlier article had converted 3 readers into paid subscribers — so this one has conversion potential too.

The work you already did stops rotting in old sessions and becomes the next thing you ship.
A3

Stoic — coaches the mind

The soft part. You work a lot; sometimes you break. To make coaching actually land, the system analysed all of your Claude.ai conversations — using Claude itself — to build a profile of you: how you act when you're angry, what drains you, how you sound when you get pissed. It saved that to a page called Leo-Psychology.

Every day the Stoic agent reads from that page plus your daily journal, then writes notes back to you — the ones that catch the exact mindset you keep losing.

PageLeo-Psychology — a profile built from your own words, read fresh every day before the agent writes to you.
A4

Note — the next thing to write

Now the pragmatist. Note reads every X/Substack note you've ever written plus all their stats — shares, likes, restacks — and compiles new wiki pages with Karpathy's method. Then it does its own web research to make sure a note actually solves a problem, and suggests the next one to write.

Real result: notes it suggested got written and backlogged — because they made sense.

Processing your data

raw chats → clean notes → profile → wiki

Raw chats are full of noise. Before anything is filed, each conversation is stripped down to what matters — your messages, your decisions, what you actually built — and turned into one clean note. Then the system reads across all of them and builds a profile of you.

prompt · profile
# Turn every chat into one clean note, then a profile of you
Read all my conversations in [folder].
For each one, keep my messages and the real decisions, drop the tool-noise.
Then write me a profile: how I think, what I get excited about, what blocks me,
how I work. Use real quotes.
Save it as a single page.
Keep private things out (optional but do it)Your export holds chats that should never enter the brain — a partner's messages, client work, anything private. Filter them before processing. Be generous: better to lose a few real ones than leak a private one.
prompt · privacy filter
Before processing, exclude any conversation that mentions
[names, topics, clients you want kept out].
Check both the title and the body. When in doubt, drop it.

Then do the same with your building brain. Your Claude Code history already sits on your machine in ~/.claude/projects/ — same idea, different source: what you actually made, not just what you talked about.

prompt · claude code pass
Read my Claude Code sessions in ~/.claude/projects/.
Keep my prompts and what I built, skip the tool-calls and any client project.
Write one clean note per session, and flag the things I built but never shipped.

A worked example — a Build suggestion

Here is one Build suggestion, traced end to end. It used your previous Claude Code conversations, created a new SEO page, and referred back to a past project — cloning a website that generated $50K.

Setup in 4 steps

two take two minutes · one the skill does for you

You end up with four clean piles — a vault, how you think, what you build, who you are — and hand them all to Claude.

Step 1~2 min
Get Obsidian

Download it, create a new vault, name it, pick a folder, and save the paths. That folder is now your brain.

Step 2~2 min
Export your Claude.ai history

Settings → Privacy → Export data. It emails you a zip in a few hours. Save it where you'll find it. You now have two raw piles: your Claude.ai zip and your Claude Code sessions.

Step 3the skill works
Hand it all to Claude

Drop in SKILL.md and SOUL.md, point at your data, and let it process the chats into clean notes, build your psychology profile, and compile the Karpathy wiki — while you watch.

Step 4set + forget
Automate

Wire the Hermes agents to a schedule so the brain reads, thinks, and writes on its own every few hours.

prompt · build my second brain
Build my second brain using the attached SKILL.md and SOUL.md.

Here's my data:

Obsidian vault: [path to your vault]
Claude.ai export: [path to your unzipped export]
Claude Code history: ~/.claude/projects/
My own work + numbers: [path to your articles / notes / analytics]
Exclude anything that mentions: [names, clients, private topics] — check titles AND bodies.

Process my conversations into clean notes, build my psychology profile, then
compile the Karpathy wiki. Before you wire up any agents, show me the
connections you found and let me approve them one by one. Don't go fully
autonomous until I've reviewed one test run.

Then it gets good. The skill reads everything and starts suggesting connections — and waits for your yes or no:

"Your trading posts and your finance builds are the same play."Want me to link them?
"These three notes are secretly one series."Approve, and it builds them into the wiki — page by page, one topic at a time.

Every yes builds another connection into the wiki. That's the brain forming in front of you.

Automation — make it run without you

The brain is built. Now you make it run on its own. Either path ends the same way: you wake up to fresh thinking every morning.

easyHermes agent

Pass your SOUL.md to your Hermes agent. It asks for the path to your vault, you give it, it sets the cron. From now on it reads, thinks, and writes to you every few hours.

when readyClaude routine

Set up a Claude routine on your computer. Pick a time when your machine is awake — otherwise it won't process. Either way, the brain now runs without you.

ResultFour agents, one wiki, every six hours. Post finds the money, Build names what to ship, Stoic catches the mindset you keep losing, Note hands you the next thing to write — and the brain gets smarter every run.
