Build your own brain. It starts with a folder.

No code, nothing to install. Just you, a Claude account with Cowork, and about an hour spread over whenever suits. I'll walk you through it.

What you'll need

A Claude account with Cowork turned on, a folder on your computer, and your own voice (optional, but it makes this much faster). That's the whole kit. We'll build the rest as we go, through the three things that make AI work: context, connections, and skills.

Make the shell

Make one new folder on your computer and call it brain. Inside it, make a few empty, labelled folders: context, clients, projects, todos. That empty shell is your brain. Everything from here is just filling it in.

Do it nowMake the folder, with those four labelled folders inside. Empty is completely fine.

Part one · Context

Teach it who you are

The folder you just made is your context. The more it knows about you, the more it can help. Talking is the fastest way to fill it.

1

Tell it who you are, out loud

Open Cowork, point it at your brain folder, turn on voice, and just talk. Who you are, what the business does, who you serve. You never have to format any of it. Talking is about four times faster than typing, and it gives the AI far richer context than a tidy bullet list would.

Do it nowRecord two minutes about yourself and your work. Ask Cowork to save it into your context folder.

2

Add what you sell, and who buys

Same again, in your own words: the problems you solve, what you charge, who your customers are and why they buy. Short, honest notes beat perfect ones. You can always add more later.

Do it nowAdd one note on what you sell, and one on who you sell to.

3

Give your work somewhere to live

Drop a file in clients for each client, a file in projects for what's on right now, and a running list in todos. Now the brain has a place for everything, not just who you are, and it can start joining the dots.

Do it nowAdd one client file, and three real things to your todo list.

Part two · Connections

Give it the tools you use

Cowork makes connecting your tools simple. Start with the two that just work, and you'll feel the value the same day.

4

Connect Gmail and Calendar

In Cowork, connect Gmail and Calendar. These two work right out of the box, and they're where most of the day-to-day value lives. Lead with what you want it to do, not the acronyms flying around.

Do it nowConnect both, then ask: what do I still owe a reply to, and what's on tomorrow?

5

Know what to watch (lightly)

Two things worth a glance: where your data goes when you share it, and keeping passwords and keys out of plain text. For a brain that's just you, this barely bites. The harder hookups, the ones that need a workaround, are where a little paid help comes in when you're ready.

Good to knowNothing to set up here. Just know the trickier connections have a safe path when you need them.

Part three · Skills

Use one, edit one, build your own

A skill is a saved way of working, so the clever thing runs the same way every time. This is the part that turns a chat box into something you can rely on.

6

Use a skill someone built

Borrow a starter skill from 8020skill.com and run it once on something real. You'll feel the difference between a one-off chat and a skill straight away: same input, same quality, every time.

Do it nowInstall one starter skill and run it on a real task.

7

Edit one to make it yours

Open the skill and change it: your tone, your steps, the file it should write to. You're not coding here. You're telling it how you'd do the job yourself.

Do it nowChange one thing in the skill so it runs your way, then run it again.

8

Build your own

Here's the move that changes everything. Do the task in a normal conversation, iterate until you love the output, then ask the AI to save those steps as a skill. Next time, it runs the same way, every time, with confidence.

Do it nowTake one task you do often. Do it once with the AI, then say: turn this into a skill I can reuse.

That's a brain. From here, it only gets better.

You've given it your context, connected your tools, and built your first skill. That's the foundation everything else is built on. When you're ready to wire it into a system that runs without you, that's where Ads to AI takes you.
