If you’d started putting away €500 a month twenty years ago, you’d have enough for a small apartment in Spain by now. But you didn’t. Neither did I. I get it.
But there’s another opportunity we’re missing right now. And it’s not about money.
Over the past year, you’ve sent hundreds of messages to ChatGPT and Claude. Had dozens of Zoom calls. Read articles, listened to podcasts, written drafts. Where is all of it?
Can you find that brilliant solution AI gave you back in January? No? Congratulations. You just threw a few thousand euros’ worth of intellectual capital in the trash.
Compound: Built from What Came Before
Compound interest. Interest earning interest. Each result builds on the ones before it. €500 a month at 7% a year turns into €260,000 over twenty years. The magic is that you don’t do anything special. You just leave the money there.
The same principle works with context. Every note, every decision, every summary is an investment. But only if it goes into a system where past investments make the next ones more valuable.
You have a meeting → write down the takeaways → a month later your AI agent spots a connection to another project → an idea appears that you wouldn’t have seen on your own. That’s the compound effect.
But if the note is in Apple Notes, the meeting summary in a Google Doc, and the idea in a ChatGPT thread, nothing compounds. It’s like putting €100 into a new account at a different bank every day. You won’t lose the money. But compound interest won’t work either.
Where You’re Losing the Compound Effect
The usual picture:
- Apple Notes — notes you’ll never read again
- Google Docs — documents you won’t be able to find in six months
- Claude and ChatGPT threads — brilliant solutions buried in chat history
- Slide decks — knowledge locked in a format AI can’t read
- A paper notebook — thoughts that exist in a single copy
Apple Notes is your retirement fund stuffed in a mattress. It isn’t working for you. And it’s losing value every day.
Why don’t projects in Claude or Gemini solve this either? Because your context is locked inside one system. You can’t work with different LLMs on the same data. Switching costs grow. The context doesn’t update itself. And most of all, that data isn’t really yours.
How to Start Building Compound Context
Rule 1: Keep Your Context in One Place You Own
Your files should live on your computer. Not in someone else’s cloud, not in a SaaS database. With you. Then even if the tool breaks, the data stays.
Obsidian, Logseq, a plain folder of Markdown files. The format matters less than the fact that it’s yours.
Yes, moving everything can take time. But AI agents can help. They’ll build the structure, sort the files, reformat them. Do it once and you won’t lose anything again.
Rule 2: Treat It as a Shared Brain
This isn’t your “second brain.” It’s a Shared Brain for you and your AI agents.
In practice:
- Documents have to make sense to both you and the agent
- You need metadata, YAML tags, links between notes, summaries and indexes
- You need access boundaries: what the agent can touch and what it can’t
- You need rules for working together. Like in a shared kitchen
You can set all this up with your agent. Together. It’s your shared project.
Rule 3: The Compound Context Protocol
All work goes into the Shared Brain:
- Have a problem? Make a file for it. Put the solution at the end, or in a file next to it
- Post drafts, long emails, recordings of talks. They all live here
- Done some research with agents? Save the results in the Shared Brain
New knowledge goes straight into the system:
- Listened to a podcast → ask the agent for a summary
- Read an article → write up the key points
- Received a slide deck → ask the agent to extract the essentials into Markdown
Work through your agents:
- Let them read your notes and show you connections you can’t see
- Let them learn how you make decisions and point out your blind spots
- Let them find unexpected connections between different parts of your life
A Word of Caution
It’s very easy to ask agents to make you a mountain of content. But you should always have an answer to “What for?” Don’t let the brain grow out of control. Yes, it’s a Shared Brain. But it’s your Shared Brain.
Who’s Already Doing This
We did the research. Developers picked up compound context first: coding agents, CLAUDE.md files, memory systems. Programmers figured it out first. As usual.
But this works beyond code. It works for any task you do digitally.
Don’t assume Claude Code is only for developers because it has “Code” in the name. Your text and your context are code too. You’re a developer too. You just don’t write in Python.
A developer develops. Yourself, your expertise, your life. You’re already doing it. I just want your effort to compound.
If your context isn’t accessible to your AI agent, it doesn’t exist.
Start today. Don’t waste your capital.
