Time to make it real. Hand your brain (your folder of knowledge files) to Claude or ChatGPT, then ask it something only your brain knows — and watch it answer without you re-explaining a thing. That moment is the whole point of all this.
Your brain is just a folder of plain text files (the .md ending means "markdown" — ordinary
text any AI can read). Because it's plain text, you don't need anything fancy: you just hand the files to a
normal chat. Pick the tool you use — the free version works perfectly. Here's the exact way to do it in each.
In a browser, go to claude.ai and start a new chat. Then:
.md files inside it (hold Ctrl, or ⌘ on a Mac, to click more than one).No upload button, or it won't take a file? Open each
.md file, copy all the text, and paste it straight into the chat. Do this for every file. It's
less tidy, but it works exactly the same.
In a browser, go to chatgpt.com and start a new chat. Then:
.md files inside it (hold Ctrl,
or ⌘ on a Mac, to pick more than one).No upload button, or it won't take a file? Open each
.md file, copy all the text, and paste it straight into the chat — one file after another. Works
the same way.
Already comfortable with a code editor or the command line? You can also
keep the brain in a project folder and let a coding tool (like Claude Code or the ChatGPT/Codex command-line app)
read the files where they sit — point it at index.md first. If that sentence meant nothing to you,
ignore it completely: the upload steps above are all you need.
Now ask a question it could only get right if it actually read your files. In that same chat (right after the files are attached), copy this and paste it as your message — type it exactly:
Using the files I just gave you, what am I working on right
now, and which tools do I use? Answer in my voice.
If it answers correctly without you explaining anything first — your brain works. Congratulations, you just handed an AI your knowledge.
If it gets something wrong, don't blame yourself or the AI. The fix is almost always a clearer file
— for example, the answer lives in a file but it's buried or vaguely worded. Open that file, make the wording
plainer, save it, then upload again and re-ask. (A "concept file" is just one of your knowledge files — like
tools.md or voice.md.)
This turns a pile of separate files into a connected brain, where one file can point to another. You do it by
adding a simple link inside your text. The pattern is square brackets around the words you want to show, then
round brackets around the file name: [words to show](file-name.md). For example, open
projects.md and add lines like these:
I'm building my project using my usual stack — see [tools](tools.md).
My writing style for it is in [voice](voice.md).
Now, when the AI reads one file and sees a link, it knows to go look at the related file too — instead of treating every file as a stranger. (If you don't add these links, that's fine — your brain still works. This just makes it tidier and helps the AI connect the dots.)
Tip: keep testing with real questions you'd actually ask. Every wrong answer is just a file that needs to be clearer — that's you improving your brain.
