The demo

Watch it remember you.

The same question, asked twice. Once before you set your system up properly, once after.

The problem

Your AI gives generic answers because it knows nothing about you.

Every fresh chat starts from nothing. You re-explain your business, your clients, your tone and your rules, every single morning, or you settle for polite boilerplate.

Without an AI OS

Example

Who am I and what am I working on?

I don't have any information about you or your work. Could you tell me more about your business, your clients and what you're trying to achieve?

0 files loaded. Memory empty.

You type the same background in again. Every session.

With an AI OS

Example

Who am I and what am I working on?

You're Sara, a freelance marketer.

Tuesday is report day for the clinic.

Your tone rule is plain English, no hype.

4 files loaded from your second brain.

Example. Your second brain, your answers, zero preamble.

The smartest assistant on earth, starting from zero every morning.

You would not hire a brilliant chief of staff and make them forget your company, your clients and your rules at 9am every day. That is exactly what raw AI does without a second brain to read.

The change

From a blank slate to a system that holds your work.

Same agent, same tools. The difference is what it is allowed to read.

Left, an agent holding an empty file case. Right, the same agent holding one full of labelled files.
Built in public

This is the exact system I run my own work on.

For more than ten years I have managed millions in ad spend and the client work that comes with it. I do not use terminal scripts, Python environments or brittle vector databases.

I set my own second brain up inside the Claude and ChatGPT apps I already pay for. When I open my laptop, my AI already knows my business, my clients, my tone and my constraints.

What you get

What is inside the AI OS Kit

Six parts. All of them tested on my own work before they were packaged.

Under the hood it is a set of files your AI reads before every chat. You never touch code.

01 · Diagnosis

The Planner

It interviews you about how you actually work, in plain English, then designs the system around your answers. Your work, your memory, your tools. Not my setup copied onto you.

Built around your role, not mine

02 · Assembly

The Builder

A step-by-step walkthrough that builds whatever the Planner designed, carrying the mistakes I made on my own build so you skip them. No terminal, no scripts.

Zero code, zero terminal

03 · Foundations

Templates and the starter files

The starting structure, starter instruction files, memory-file templates and a first-week routine, so the thing gets used instead of admired.

Ready-made files you fill in

04 · Proof

The five-question self-test

One week in, a fresh chat has to answer five things about you cold. Five clean answers means it works. A weak one points at the exact file to fix. Plus a one-page register of what your AI can actually reach, with the date it last did.

You know it works, not hope

05 · Lifetime

Free updates forever

Claude and ChatGPT keep moving. When they change what a desktop app can read and write, the blueprints and templates get refreshed and you pay nothing more.

Your 3D Brain

Your second brain as a spinning 3D galaxy: every note a glowing node, every link a thread, click a node and the note opens. Runs on your own computer, reads your notes, sends nothing anywhere. One paste installs it.

The part people film

Bonus: Your 3D Brain

See everything your AI knows about you, spinning.

Every note a glowing node, every link a thread, click a node and the note opens. It runs on your own computer, reads your second brain, and sends nothing anywhere. Your AI installs it from one paste.

Ships inside the AI OS Kit. Windows or Mac. Nothing in the main setup depends on it.

How it works

Running in three parts, in one sitting

No scripts and no technical hurdles. Built for people with a day job.

Three panels: an agent asking a question, an agent organising files into a labelled set, an agent presenting a clear answer
Connect

Step 1: Make the folder and connect it

Make one folder, copy the starter files into it, and connect it to the Claude or ChatGPT app you already use. A thirty-second test proves it worked.

Interview

Step 2: Answer the interview

Paste the Planner into the chat. It asks about your work, your clients, your rules and your tone, in plain English. You answer honestly.

Build

Step 3: Build it and switch it on

Paste the Builder. It writes your files one at a time, you approve each one, then it switches itself on. Open any new chat and it already knows you.

Pricing

One price, yours forever.

No subscriptions. No API meters. Buy it once and keep it.

Answers

Questions people ask.

Do I need technical or coding skills?

None. No terminal, no Python, no command line. This is the version for people who will never open a terminal: your AI interviews you and designs the system, instead of handing you a template to fill in. If you can move a file on your computer and answer straight questions in plain English, you are ready.

Are there subscriptions or hidden costs?

No. One payment of $47. The files are yours, on your own machine, and every future update is included at no extra cost.

Which AI tools does this work with?

It works with the Claude or ChatGPT you already have. The AI OS Kit assumes a paid plan, because that is what I run. You do not need any paid developer APIs.

What is your refund policy?

14-day money-back guarantee. Set it up, use it, and if it does not save you hours, email me inside 14 days for a full refund. No awkward questions.
