Claude Code가 당신의 두 번째 뇌가 될 수 있다

Noah Brier might have the coolest Claw code setup I've ever seen. Noah Brier는 제가 본 것 중 가장 멋진 Claude Code 셋업을 갖고 있습니다. He rigged a home server in his basement, put his Obsidian vault in it, and then runs Claude code on top so he can think, research, write, and even ship code right from his phone. 지하실 홈 서버를 구축하고 Obsidian 볼트를 그 안에 넣은 다음, 그 위에서 Claude Code를 실행해 Today, he shows us how he uses Claude Code as a true second brain, a thinking partner that asks him sharp questions, pulls research from his whole note archive and the web, and even keeps a running log of what he's learned and what his best ideas are. 오늘은 Noah가 Claude Code를 진정한 두 번째 뇌, 즉 사고 파트너이자 연구 도구로 어떻게 활용하는지 보여드립니다. And he walks us through his whole stack and his whole [music] workflow. 그리고 전체 기술 스택과 [음악] 워크플로우를 함께 살펴봅니다. If you want to learn how to use claude code as a true second brain, this is the episode to watch. Claude Code를 진정한 두 번째 뇌로 활용하는 법을 배우고 싶다면 딱 맞는 에피소드입니다. Let's dive in. 바로 시작해볼까요. [music] [음악] Noah, welcome to the show. Noah, 환영합니다. Thanks for having me. 초대해 주셔서 감사합니다. I'm excited to have you. 와 주셔서 정말 기뻐요. Uh it's really good to uh get to chat. 이렇게 대화 나눌 수 있어서 정말 좋습니다. This is our first interview in probably like 5 years. 아마 5년 만에 처음 하는 인터뷰인 것 같아요. You were one of the for people who don't know uh you were one of the first uh super organizers interviewees. 모르시는 분들을 위해 말씀드리면, Noah는 제가 운영하는 뉴스레터의 초창기 독자 중 한 분이었어요. That was the newsletter that turned into every and um I I love the way that your brain works. 그 뉴스레터가 Every로 발전했는데, Noah가 도구와 사고 방식에 갖는 독특한 취향이 정말 마음에 들었어요. Uh you have this like uh really interesting taste for tools for thought and back in the day you were using Evernote in all these really interesting ways. 생각을 위한 도구와 배백, 정보 관리에 대한 정말 흥미로운 감각을 갖고 계시잖아요. Um you were uh the co-founder of a really cool startup uh called Percolate. Percolate라는 멋진 스타트업의 공동 창업자이시기도 하고요. Uh, and then another one called Variance and now you're running Alfik, which is an AI strategy consultancy. 그다음엔 Variance를 창업하셨고, 지금은 Alephic을 이끌고 계시죠. And um I'm just really excited to see how your um mind has uh started to use these AI tools now that now that they're uh now that they're, you know, working so well. 그리고 이 새로운 AI 도구들을 어떻게 활용하고 계신지 정말 기대가 됩니다. And I know you have some pretty cool Claude code stuff to show us. Claude Code 관련해서 보여주실 멋진 게 있다고 알고 있어요. So yeah, thanks for coming on. 와 주셔서 정말 감사합니다. Thanks for having me. 초대해 주셔서 감사해요. Yeah, I'm super excited. 네, 정말 기대되네요. That was a a fun interview all those years back. 몇 년 전 인터뷰도 정말 즐거웠어요. It was it was really really fun. 저도 그랬어요, 정말 재밌었죠. Um, so I want to just like dive right into the the like the thing that I think is so cool about what you're doing. 바로 핵심으로 들어가고 싶은데, 제가 가장 인상 깊게 본 부분부터 시작하고 싶어요. So I know you have a whole like vibe coding setup that you built for yourself. 본인만의 vibe coding 셋업을 구축하셨다고 들었어요. Can you talk us through that? 한번 설명해 주시겠어요? Yeah, I wouldn't uh I'm not sure about actually the vibe coding part of it. 네, 사실 vibe coding이라는 표현은 좀 맞지 않는 것 같아요. Um uh I have a a sort of fairly heavy duty clawed code setup. 꽤 본격적인 Claude Code 셋업을 갖추고 있긴 한데요. Um but actually uh mostly not for code. 근데 사실 코드 작성 용도로는 거의 안 써요. Um so uh since those days of uh super organizers like many people um uh I've abandoned Evernote um and uh switched over to Obsidian. 그때 이후로 많은 사람들처럼 Evernote를 버리고 Obsidian으로 갔어요. And one of the big advantages with Obsidian as a note-taking platform is that it's a bunch of markdown files and a bunch of folders. Obsidian의 큰 장점 중 하나는 노트 파일이 일반 마크다운 파일이라는 거예요. um and uh they can then be synced with git and you can do lots of other fun kinds of things. git으로 동기화할 수 있고, 그 외에도 여러 재밌는 걸 할 수 있어요. And so actually probably my number one claude code use is using it as a tool to interact with my notes. 그래서 제 Claude Code 1순위 활용법은 노트와 상호작용하는 도구로 쓰는 거예요. Um and so that uh I've got a fairly serious cloud code setup that I use with Obsidian. 그래서 Obsidian과 함께 꽤 진지하게 Claude Code를 세팅해놨어요. And um my most recent obsession um has been uh standing up a server in my house so that I could also use claude code on my phone. 그리고 최근 제 집착은 집에 서버를 구축해서 폰으로도 접근할 수 있게 만드는 거였어요. This is incredible. 정말 대단한데요. I want to I want to go through all of this. 이거 다 하나씩 살펴보고 싶어요. So um where should we start? 그럼 어디서부터 시작할까요? Should we do should we do how you use cloud code as sort of this like research assistant notes organizer notetaker thing or should we start with uh how you use it on your phone? 연구 보조나 사고 도구로 Claude Code를 활용하는 부분부터 시작할까요? Um, we can use it. 그걸로 해도 되고요. We can start uh with just the sort of general part of it. 그냥 일반적인 개요부터 시작하죠. That that might be the sort of easiest. 그게 가장 시작하기 쉬울 것 같아요. The phone is really just an extension of that same thing. 폰은 그냥 같은 시스템의 연장선이에요. I um I would say sort of generally, and this is something I feel like not enough people talk about with AI is like one of the things I find really extraordinary about it is the ability for me to um work really productively on my phone. 전반적으로 말씀드리고 싶은 건, 이건 생각보다 충분히 이야기되지 않는 것 같아요. And that's been like a huge huge change because so much of what I do is sort of writing or coding and the phone is definitely not the best place for that. 그게 제 작업 방식을 정말 크게 바꿨어요. 제가 하는 일의 상당 부분이 그런 식이거든요. And you know even the phone wasn't always the best place for doing research and thinking um I felt like my computer was a better place for it which is why I've been such a sort of notetaker. 폰도 예전엔 조사나 사고를 하기에 딱 좋은 환경은 아니었는데, 그게 변했어요. And um you know I have found whether it's like claude code and obsidian or um I mean even claude code and code right. Claude Code와 Obsidian이든, 다른 도구든 간에 정말 많이 달라졌어요. So, like the other piece of it is being able to then, you know, if you see something go wrong, being able to sign in on your phone and have Claude Code push a small update to something because you just realize it while you're out is amazing. 그래서 뭔가를 보게 됐을 때 Claude Code로 접속해서 작은 업데이트를 푸시할 수 있다는 게 정말 놀라워요. But then even like uh um you know, I use quite a bit of uh uh Grock voice mode and you know, I find that that as a sort of like alternative way of working through problems. 그리고 저는 이동 중에 Grok 보이스 모드도 꽤 많이 써요. I have a Tesla so now it's baked into the Tesla. 테슬라가 있어서 이제 차에 바로 내장돼 있어요. Um and uh you know it's just I and you know obviously all the sort of other Chad GBT and Claude and all these things of just being able to sort of like go and do research and really think and and explore things in this device that's always been useful but like not useful for deep work. ChatGPT랑 Claude 같은 것들도 쓰긴 했는데, 솔직히 말하면. I think is probably um something most people would agree with is that the phone has not [laughter] been the best place to kind of do deep coding and research work. 대부분 사람들도 동의할 거라고 생각하는데, 폰이 아직은 최선의 환경이 아니에요. And I feel like it it it's really changed my ability to do that. 근데 이게 정말 제 작업 방식을 바꿔놨어요. Wait, I got to stop you. 잠깐만요. So, you're using Grock voice mode and and is that specifically because it's built into your Tesla or using it um in situations where you could also use, for example, CHBT voice mode? Grok 보이스 모드를 쓰시는 게 차에 내장돼 있어서인가요, 아니면 다른 이유가 있나요? No, I'm using it because it's way better than any of the other voice modes. 아니요, 다른 보이스 모드보다 월등히 낫기 때문에 써요. And I will fight anybody who says anything different. 반론은 안 받습니다. Okay. 알겠어요. No, tell me like what is what do you like about it? 그럼 좋아하시는 이유를 말씀해 주세요? Why is it better? 왜 더 낫죠? I to be fair um uh 솔직히 말씀드리면, OpenAI launched their real-time API which may or may not be baked into chat GBT voice. OpenAI가 실시간 API를 출시했는데 ChatGPT에 들어갔는지 아닌지는 잘 모르겠어요. Now I it's not totally clear but the old voice mode was based on 40 and I just found it to be completely unusable. 예전 보이스 모드가 GPT-4 기반이었는데, 솔직히 별로였어요. Um and uh uh Gemini's voice mode I just didn't find to be smart enough. Gemini 보이스 모드는 충분히 똑똑하지 않다고 느꼈어요. Um and I just found Grock's voice mode to be significantly smarter than anybody else's. Grok 보이스 모드가 다른 것들보다 훨씬 똑똑하다고 느꼈어요. Um, you know, I'm using Grock 2, three, four. Grok 2, 3, 4를 쓰고 있어요. I don't even remember what whatever the latest 어떤 버전인지 기억도 안 나는데 최신 버전이요. the latest one. 최신 버전. Yeah. 네. Yeah. 네. But not the super I don't have the most expensive account. 가장 비싼 요금제는 아니에요. Super heavy or whatever. 슈퍼 헤비 같은 거. I don't have super heavy. 슈퍼 헤비는 없어요. Um, but I just find it to be much better. 그냥 훨씬 낫더라고요. It does tool calling way better than any of the other ones. 툴 호출을 다른 것들보다 훨씬 잘 해요. That's that's I found to be a major weakness of the voice models is that they don't do great tool calling and research. 보이스 모드의 큰 약점이 그거라고 느꼈는데, 툴 호출이나 웹 검색을 제대로 못 하거든요. And um uh Gro seems to have solved that. Grok은 그걸 해결한 것 같아요. So, no, even before it was loaded in my Tesla, um I dropped my daughter off at summer camp this summer up in New Hampshire. 테슬라에 내장되기 전에도 딸 학교 데려다주고 나서 So, I had a 5-hour drive on my own, and I spent like 2 hours researching and essentially like working through a piece. 5시간 운전을 혼자 했는데, 그중 2시간을 Transformers에 대한 글 쓰면서 연구했어요. Um, and I did it by just like connecting it to Bluetooth and just sort of sitting there in the car. 블루투스에 연결하고 그냥 앉아서 하는 식으로 했어요. And, um, I found it to be by far the uh the best of the voice modes. 지금까지 써본 보이스 모드 중에 압도적으로 최고였어요. I I hope these other models catch up there cuz I would I would love more really good voice modes. 다른 모델들도 따라왔으면 좋겠어요. 정말 진지한 보이스 AI 경험을 원하거든요. I mean, I had a mind-blowing session this weekend and uh I'm giving a talk and I'm sort of have some ideas. 이번 주말에 정말 놀라운 세션을 했어요. 컨퍼런스 강연을 준비 중인데 I think it's generally going to be about Transformers eating the world and um so I was sort of catching myself up on self attention and exactly how it works. 전반적으로 Transformers가 세상을 집어삼키는 것에 관한 내용이 될 것 같아요. And um I did like an hour session and it really I I it like was by far the sort of best explanation I've ever read for it and or ever heard I guess. 한 시간 세션을 했는데, 지금까지 읽거나 들었던 것 중 가장 뛰어난 설명이었어요. And so yeah, I' I've just found it to be a kind of pretty extraordinary product. 정말 대단한 제품이라고 느끼고 있어요. I do love voice mode for that. 보이스 모드 그 용도로 정말 좋아해요. Um it's sort of like it's the it's a podcast made specifically for you about whatever you're curious about and that's really cool. 바로 나를 위해 만들어진 팟캐스트 같다고 할까요, 지금 생각하고 있는 것들에 대한. I went up to I 저는 이번 주말에 I drove up state this weekend and I've been reading um I've been reading the Iliad and so I had it on audiobook and then I had some questions as I was driving and so I unfortunately use CHBT voice mode because I didn't know about Grock so I wish that uh Grock's voice mode so I wish that uh we had had this conversation before then but the thing about chbt voice mode is yeah 이번 주 드라이브하면서 일리아드를 읽고 있는데, Claude한테 설명해 달라고 했어요. I think when it first came out it was cool but it just hasn't gotten as smart as the models are are 처음 나왔을 때는 괜찮았는데, 점점 스마트해지지는 않는 것 같아요. And they they gave it this new personality that I had to get used to where every time you ask it a question it's go it goes like 그리고 새로운 성격이 생겼는데, 매번 제 말에 과도하게 동조하는 게 적응이 필요했어요. oh yeah uhhuh 오 그렇군요. well you know and it's like it's just this like weird Gen Z thing that it feels like it's has a little bit too much onwe or something like doesn't actually care about you. 그게 이상한 Z세대 느낌인데 정확히 뭔지 모르겠어요. I don't know what that is. 뭔지 모르겠어요. So I had to get used to that. 그래서 적응해야 했어요. Rock has a stoner mode for what it's worth. Grok은 참고로 스토너 모드가 있어요. [laughter] [웃음] Yeah. 네.
