Build a second brain for your project work

I stopped re-explaining myself to every AI by giving it one folder it reads first — my context, on tap.

Story behind

Every AI chat, I used to type my context from zero.

I'd re-explain my business, how I work, the project I'm on.
The agent was sharp for five minutes.
Then I closed the tab,
and the agent forgot everything.

So what if it could read all that before every chat,
without me typing it again?

My Google Drive "second brain" solves it.
One synced folder the agent reads first, in two parts:

Brain — my rules, skills, and preferences
Context — the client, the project, the work at hand

Now I set it up once.
Since it's one drive, synced to my office and home laptops,
the AI picks up my work any time, on any device.

Why this helps you

Never brief the AI twice — your identity, rules, and project context load automatically. You start every session already understood.

Any agent, same context — Claude, a code agent, a phone app: they all read the same folder. You're not locked into one tool.

Resume cold — open a project after a month and the work log tells the agent, and you, exactly where things stood.

It compounds — each correction you capture makes the next task faster. The system improves as a by-product of using it.

No new software — it's just folders and text files in storage you already pay for. Nothing to host, nothing to break.

Good to know

Keep secrets out of it — store API keys in a password manager and reference them. Never paste real credentials into the files.

Stable vs moving — if you're editing your Core file every day, that's probably project context in the wrong place. The brain should change slowly.

Keep it alive — every time you repeat yourself to the AI, write the answer down once. That habit is what makes the folder smarter each week.

Start tiny — a single Core file already beats nothing. Add Rules and Skills only as real patterns appear; don't build the whole cathedral on day one.
