Building a second brain that every AI tool shares

Why I needed it written down

Priorities change a lot. Decisions get made in a hallway and forgotten by Friday. A client's preferences live in someone's memory, and that someone is me.

With ADHD, a long list of everything that matters makes me freeze.

What's in the folder

A folder of ordinary text files. No special software. It holds four things:

• PrioritiesWhat matters right now, ranked. A one-page "what's true today" summary is rebuilt every 15 minutes, so it's never a guess.
• DecisionsA running record of what we chose and why, so I don't relitigate it in three months. It's over a thousand lines long now.
• Daily logOne file a day, added to as work happens. I've got more than 120 days of it.
• MemoryShort notes on how I like things done, saved the moment I correct something.

Because it's plain files, any AI tool can read it. Nothing is locked inside one product.

Built for how my brain works

Everything it tells me is bullets with the bottom line first. Long paragraphs get cut.

When the product name changed

In June, mode40 locked its product into one platform, the Singularity, and retired the older product names.

I changed it in one place. Every tool I use picked it up the next time it read the brain. The rule I follow now: when a fact changes, search for the old one everywhere and fix what depended on it, the same day.

Without that, I'd be re-explaining it to each tool, one at a time.
