핵심 요약
AI '제2의 뇌'를 5단계로 설명한다. 핵심은 데이터가 곧 나만의 해자(moat)라는 것, 그리고 나중에 "어떻게 꺼내 쓸지(질문)"를 역설계해 폴더·라우팅 구조를 짜야 에이전트가 환각 없이 정확히 찾아낸다는 점이다.
주요 포인트
- 제2의 뇌 = 마크다운 파일·폴더 구조. 클로드코드뿐 아니라 코덱스·헤르메스 등 어떤 에이전트와도 호환
- 핵심 질문은 "에이전트가, 그리고 내가 그걸 다시 찾을 수 있는가" — 아니라면 라우팅/폴더 설계가 잘못된 것
- 거꾸로 설계: 미래에 데이터를 어떻게 활용할지 먼저 정하고 그에 맞춰 저장
- 단순 링크 모음 → 클러스터 → 관계 매핑(relationship mapping)으로 단계적 진화
Today I'm going to explain the different levels of building your own AI second brain. You can see here we have a visual of three very different types of data. This one is where we have our context really starting to form and we're starting to see some relationships and we're starting to see some different nodes and entities form. And then as we continue to scale this up, add more knowledge, more knowledge, more relationships, we start to get something that looks a little bit more like this where we have clearly different clusters and inside of all of these nodes, we can see how they relate to each other. And then over here, we're taking all of those relationships a step further, and we're able to then start to see how everything really pieces together rather than just having files that sort of link back to each other. This is relationship mapping. And so really, the idea of an AI second brain has blown up because we're all trying to get as much information out of our heads into our systems as possible. That's the true value. Your moat is your data. It's your IP. But the process of organizing that into a system so that you can use it with a bunch of different AI models and so that it can actually recall things in a way that makes sense rather than just hallucinating or spending a bunch of your time and tokens trying to look through everything. That's the issue. So clearly all of this is my real data and this is what the actual project looks like. It is my Herku project. I have a bunch of folders and files here and at the end of the day that's basically all it is. It is markdown files that are organized in a way that I understand and that my agents understand. And so yes, I'm going to walk you guys through what I have here and how it works. But I also have this other project where I'm going to show you if you're starting from scratch or if you feel like maybe you're in between level two and three, how we can actually look at the differences and what it might look like to scale up your own systems and start to add context in different ways. So super excited to dig into this today and I don't want to waste any of your guys' time. So let's just start looking at these five levels and how they differ. All right, so every level of a claude code second brain and I'm going to be obviously kind of referring to cla code a lot, but keep in mind this can be used with any AI model. I use my second brain all the time with codecs as well. I use it with Hermes agent. This can be used by different agent harnesses because it's just files and folders. So what is the actual job of a second brain? A lot of people probably define this differently, but the way that I think about it is that it's a place for me to save notes, meeting recordings, ClickUp threads, stuff like that. I can save it there, and then it helps me basically ingest it and get it into the right spots so that it can actually find it later. And so that's really the thing to think about is can your agent find it again? and could you find it again? Because if the answer is no, then you probably don't have the right routing or folder architecture set up, which is what I'm here to talk about today. And one other sort of mindset thing that I want to get out there before we dive into these five levels is that you kind of have to work backwards. You want to reverse engineer based on the question. So, this will start to make more sense as we get into it. But really, what you should be thinking about is how do I want to use this data in the future? Because how it's going to be accessed and recalled determines the way that you put it in in the first place. For example, a basketball hoop and a basketball. We know what shape the hoop is and we know that the ball needs to go through. So why would we ever design the ball to be a giant square because it just wouldn't fit through the hoop. So that would make no sense. So you need to start with the end in mind a little bit. Once again, I will show you exactly what I mean by that as we continue on. Because remember, we're trying to get to the point where your second brain knows everything about your business, about you, your relationships. It knows everything to the point where it probably can recall stuff better than you can because it has a better memory and it can search through things way faster than you can. So, we've got five different levels to talk about and they each kind of have different questions. So, level one is, can you find the file or the info by looking for an exact word or name? Level two is, can you pull everything on a certain topic together? Level three is, I searched for different words than I wrote. So, semantic search, you're searching for meaning rather than an exact word match. And then trace relationship chains. Can you ask about topic X? And then trace that all the way back to topic A. And then level five is just kind of making this whole second brain thing super autonomous to the point that you don't ev
