DUMBER THAN A FOLDER that galaxy in the background is his Obsidian vault > looks incredible > does nothing dead notes, zero connections, zero value extracted from any of it > the fix isn't taking better notes > it's building a pipeline where Claude Opus 4.8 does the research, NotebookLM does the analysis, and every session feeds your vault automatically one command: > Claude Code searches YouTube for 10 relevant sources > passes them to NotebookLM - Google's servers do the heavy processing, not your tokens > NotebookLM runs full analysis, generates infographics, mindmaps, flashcards > everything lands as structured markdown in your Obsidian vault, linked and ready total time: 6 minutes > after a month the vault knows your thinking style. after a year it's a trained research assistant the $300K AI architects aren't taking better notes > they're building systems that compound 30-minute setup. full step-by-step in the article below 👇show more

Obsidian became a neural network with 184,320 links and... now runs as the most powerful second brain ever built for $0. 12,480 notes in 1 vault, 0 folders, 0 tabs, and he hasn't opened Notion in 7 months. Every night at 2 AM Claude Code walks the vault, reads all 12,480 notes, embeds them, and hunts for the pairs that should be linked but never were. Last night it found 61 and he accepted all 61. That's the move nobody makes by hand, because 12,480 notes means 77 million possible pairs, and a human links maybe 4 a day while the agent links 61 while he sleeps. Capture takes 2 seconds, a voice memo lands as a note in 1.4, a clip becomes a linked node on its own friction is what kills a second brain so he deleted the friction. Recall latency sits at 38 milliseconds, which means the graph answers before he finishes doubting himself. 36 clusters formed without him, decay score holds at 0.03, and 97% of everything he ever wrote is still reachable, while most people's notes rot past 90% in a year and turn into a graveyard with good search. Yesterday it surfaced 9 forgotten notes, one of them 412 days old, and that one became a product he shipped 48 hours later. Plain .md files on a laptop, no cloud, no subscription, no company that can delete his brain on a Tuesday. The graph doesn't store what he knows. It stores what he'd never have connected alone.show more

A Harvard sophomore pointed Claude Code at his Obsidian... vault and woke up to 1,847 notes he never wrote. The vault started in September 2024 with 210 notes lecture scraps, 4 problem sets, 3 half-finished essays and by March it was dead, because nobody links notes by hand at 2 AM. So he handed the folder to an agent: read access to 210 files and one instruction, find what connects. It ran for 6 hours and built edges he'd never seen, wiring a thermodynamics lecture to a supply-chain note to a Douyin livestream case study he saved in 2023 and forgot. Graph view at 4 AM showed 1,847 nodes and 11,400 links, a white sphere so dense the center goes solid. His midterm was 9 days out, so he skipped the textbook and asked the vault instead, and it answered in his own words from 3 semesters back. Now the agent runs nightly, pulling 40 new notes a week writing summaries, tagging, linking, killing duplicates while he hasn't typed a note in 5 weeks. He opens the graph most mornings and scrolls for something he doesn't recognize, and there's always something. Tuition runs $59,320 a year; the vault cost one afternoon of setup. He built a second brain, then stopped using the first one.show more

Anthropic didn't build his memory system. He built it... himself, and what you're looking at is the proof. Same source, no gatekeeping. The Obsidian CEO published it, anyone can install it. That's not a screensaver on his second monitor. It's his vault. Every point of light is a note. Every cluster is a project his AI already understands without being told again. He doesn't even touch the keyboard to move through it. One hand up, and the whole cluster tilts and spins, like he's turning a globe that happens to be his own head. A year ago he opened a new AI tab every morning and explained himself from scratch. Who he is, what he's building, what he wants. 200+ hours a year, just re-introducing himself to a machine. Then he stopped writing prompts and started writing one file instead. It loaded before every session. His goals, his projects, his blind spots. Claude read it first, every time, without asking. Now the cluster on that screen keeps growing on its own. New notes link themselves. Nothing gets explained twice. He's not showing off code. He's showing off the machine that finally stopped forgetting him.show more

HE BUILT A 100% PRIVATE SECOND BRAIN IN OBSIDIAN... TO AUTOMATE HIS RESEARCH USING HERMES AGENT AND NOTEBOOKLM He visualizes his entire knowledge graph on-premise without paying for cloud subscriptions By connecting Hermes Agent and NotebookLM, developers can index hundreds of documents and generate content locally Four components of this local knowledge architecture: 1. Memory layer - set up an Obsidian PARA vault to store markdown notes and profiles 2. Agent layer - connect Hermes Agent to write files and run background scripts 3. Synthesis layer - use NotebookLM to create structured overviews from raw transcripts 4. Automation layer - trigger cron tasks to synchronize files and calendar standups The setup saves over $4,000 annually while keeping all private files offline Get the full step-by-step configuration guide and setup commands in the article below ↓show more

I HAVEN’T OPENED A SINGLE BOOK THIS MONTH. CLAUDE... READ 34 OF THEM FOR ME I built a vault in Obsidian, connected Claude and added Notebooklm went to sleep woke up with flashcards, mind maps, and an AI that answers from my own notes only my friends are still highlighting pdfs manually the only thing separating us is one setup: claude + obsidian + notebooklm every idea captured. every book processed. zero knowledge lost if this is the setup you’ve been looking for - like & bookmark so you don’t lose itshow more

This is how you compress 100 hours of content... into 10 minutes! just tried NotebookLM + Obsidian and it's actually insane > the "YouTube to NotebookLM" extension lets you dump entire channels into NotebookLM and get a structured mega-summary in minutes > Audio Overviews turns any PDF, report or notes into a podcast-style dialogue - perfect for walking or driving > Book Filter: upload your Obsidian vault + a new book, ask "is there anything new for me here?" - if no, skip it and save dozens of hours this combo feels like compression for knowledge the stack: 📁 NotebookLM ↳ 📁 YouTube to NotebookLM Chrome Extension ↳ this combo + Obsidian vault = unfair advantageshow more

A kid in my DMs asked me if $533... in two days is good. He launched his store 48 hours ago. He's 16. 30 orders. 5% conversion rate. Day two. Most people spend two days picking a niche. This kid already has 30 customers. I asked him how he built it. He said he described what he wanted to Claude and it did everything. Product pages, descriptions, ads. One evening and $20. Then he asked me how to set up taxes. He doesn't even know how taxes work yet. He sent me everything he used. All of it is in the article.show more

A CHINESE TRADER BUILT A SECOND BRAIN IN OBSIDIAN... THAT GENERATES 3 TRADING IDEAS EVERY MORNING AT 6AM AND MADE $180,000 IN 6 MONTHS. No Bloomberg terminal. No analytics desk. No team of analysts. A Mac Mini by the wall. An iPhone in his pocket. One local Obsidian vault. Six N8N pipelines running 24/7, pulling every article he reads, every podcast he listens to, and every voice note he drops into a Telegram bot—directly into the vault. Every night, a neural network reads across 4,000 connected notes and finds the strongest connections between fresh information and old theses. Every morning at 6AM, a brief lands in his inbox: - 3 trading ideas with confidence scores - The emerging thesis of the week - Any note that contradicts an active position The system only wakes him up when a fresh note contradicts his thesis, or when an idea breaks 90% confidence. Everything else runs without him. The monthly bill: $120 in API costs. The monthly return: approximately $30,000 into the account. Traditional quant funds pay teams of 8 people to produce the same flow of insights. He pays $120 and a Mac Mini. The full system breakdown is in the article below.

THIS MAN HASN’T HAD A SINGLE ORIGINAL IDEA IN... 8 WEEKS. CLAUDE HAS ALL OF THEM BEFORE HE WAKES UP he gave claude his obsidian vault on a saturday by monday it found a link between two notes written 6 weeks apart in different folders he turned that connection into his best-performing post his competitors are still organizing folders and writing morning pages and brainstorming in notion the only difference is one file called CLAUDE.md every note = fuel and every morning = synthesis and every week = ideas compounding faster than he can publish them this is not a tool anymore and this is not even an assistant this is a second brain that studied you for 2 months straight bookmark & like this or lose it forevershow more

YOUR OBSIDIAN VAULT READS ALL 2,000 NOTES TO ANSWER... ONE QUESTION. THAT'S NOT A SECOND BRAIN. That's a hoarder with markdown files. Hundreds of thousands of tokens burned per answer, and it still grabs the wrong note half the time. A real second brain runs on a graph: a router, an index, nodes, edges. Fable 5 reads 2-3 files instead of the whole vault. Answer back in under a second. The graph view everyone screenshots in Obsidian is a poster. The index is the actual engine.

My little cousin configured a $103,000 BMW last night.... He's 15. I laughed. Then he showed me his Shopify dashboard. 7 million orders. Revenue chart that doesn't fit on the screen. $500,000 last month. He's not even old enough to drive the car he's about to buy. I asked him what tools he uses. He said Claude and six prompts. $20 a month. That's it. What broke me is he said he still feels behind. Most people twice his age don't make that in a year. His exact setup is in the article.show more

I genuinely don't understand why everyone isn't using this... yet Andrej Karpathy, a co-founder of OpenAI, posted a simple idea that hit 16 million views: stop using AI to write code, use it to build a second brain. You point Claude Code at a folder, drop in any source, an article, a transcript, a PDF, and Claude reads it, links it, and files it into a living wiki of everything you know. It compounds like interest, the more you feed it, the smarter it gets. Here's the whole thing: > Install Obsidian, create a vault, open it in Claude Code > Paste Karpathy's wiki idea file and tell Claude to build it > Claude makes three folders: raw for sources, wiki for its pages, a CLAUDE.md that runs it > Drop any source into raw and say "ingest this" > Ask questions across everything, forever Five minutes to set up, and you never start from a blank chat again.

A 20-year-old student from China, Li Hao, built an... AI speed radar with Claude alone and sold it to a city district for $317,000 He wrote the whole thing in 9 days, spending about $20 on Claude API calls He set an old camera on his balcony, pointed it at the intersection below, and let Claude watch the road Claude tags every car, motorbike and pedestrian in real time, 653 in five minutes, and flags anyone over the limit The moment a car speeds, Claude clips the video, reads the license plate, matches the owner, and emails the fine on its own A normal radar takes one photo and misses half the time. Claude records full video, so there is nothing to dispute, and the fines go out with no operator He walked into the district office with a flash drive and asked for 10 minutes. he left with a contract Every Claude config he used is in the articleshow more

UPDATE The man in the video has now come... forward and provided the following video to explain what he brought into Mitch Sylvester's store. Information that I have received includes - He avoided calls from the RCMP for several weeks - He left the store with the item - He is claiming it was just a misunderstanding - The RCMP still has an open investigation - Charges could still be filed - There was one item, not two as previously reported If this was infact the item he brought into the store along with his "This is for Mitch" message, this is hands down the dumbest thing anyone can do to the employees of the store, and to Mitch directly. There still is an active investigation as showing staff a bullet, or a pen that looks like a bullet, uttering a threat, and not responding to the RCMP for weeks, is still grounds for criminal charges. Thank you to the dozens of people who did recognize the man, and provided tips.show more

This Chinese guy built a Second Brain in Obsidian... and every morning gets 3 trading ideas that brought him $180,000 in 6 months. Inside he runs a pipeline of 6 workflows on N8N that automatically pulls every read article, listened podcast, and voice note into a shared Obsidian vault, and a neural network analyst every morning at 6:00 finds connections between the fresh and the old and puts the 3 strongest trading ideas for the day into the inbox. No analytics desk, no Bloomberg terminal, no Telegram chats with traders. Just a Mac Mini by the wall, an iPhone in the pocket, and 1 local Obsidian vault. And traditional quant funds keep entire teams of 8 people on salary for the same flow of insights, while his expenses are only subscriptions to Readwise, Whisper API, and N8N hosting. 6 pipelines process about 200 sources a day and close the monthly API bill at about $120. The Mac Mini itself stores the entire vault and keeps the neural network analyst running 24/7, and from the iPhone the owner drops any idea he hears on the go into a Telegram bot, and it lands in the vault inbox in just 30 seconds. The starting instruction that sits in the VAULT.md file at the root of his vault looks like this: "you are the AI analyst of a solo trader. you read his vault every morning at 6:00, find connections between fresh and old notes, and deliver 3 trading ideas he can verify in the hour before the market opens. pipelines: // Reader (pulls every article and highlight from Readwise, Twitter bookmarks, and Kindle into /notes) // Listener (transcribes podcasts through Airr and voice notes through Whisper, puts them in /notes) // Catcher (accepts any message from the Telegram bot and writes it to /inbox with a timestamp) // Connector (every night reads across the entire vault and updates the connection graph between 4,000 notes) // Briefer (at 6:00 AM writes a brief: 3 trading ideas for today plus the emerging thesis of the week, puts it in /inbox) // Mobile (lives in the iPhone, answers any question about the vault by voice, and confirms alerts while the owner is on the go). you wake the owner with a push notification only when a fresh note contradicts his active thesis or when 1 of the 3 morning ideas has a confidence score above 90%." This instruction immediately sets the role for the system and the limits of its autonomy. It knows it is supposed to connect new with old on its own. It knows it is supposed to prepare 3 trading ideas every morning on its own. It knows it connects the live trader only when a thesis is contradicted or an ultra-confident idea appears. → Reader pulls about 80 articles and highlights a day from Readwise, Twitter, and Kindle → Listener transcribes 4 to 6 podcasts a week through Airr and Whisper → Catcher intercepts all voice and text ideas through the Telegram bot, averaging 15 to 20 a day → Connector updates the connection graph between 4,000 notes every night, adding 25 to 30 new edges → Briefer puts a fresh brief with 3 trading ideas and the emerging thesis into the inbox at exactly 6:00 → Mobile answers any question about the vault by voice and confirms alerts right from the iPhone And only when a new note contradicts his active thesis or 1 of the ideas breaks 90% confidence does the orchestrator raise the owner with a push notification. And when the trader at that moment is driving to the gym or eating breakfast, the Mobile agent in his iPhone answers any quick question about the vault by voice: what he wrote about this ticker last week, which 3 sources support the idea of long NVDA, and what counter-thesis already sits in his notes. The trader makes the decision and sends the order before New York opens. The fresh brief from last Monday looks like this: "reader: 78 materials added over the weekend, 11 of them about semiconductors, 4 about energy, 3 about biotech. passing to connector." "connector: 27 new connections found between fresh materials and the vault, the strongest one is that the Goldman report from Wednesday matches the NVDA thesis you wrote 3 weeks ago." "briefer: 3 trading ideas for today: long NVDA (confidence 0.84), short Tesla at the close of the quarterly report (0.71), watch URI (0.62). emerging thesis of the week: the market is underpricing capex on data centers." "alert: your fresh note about long-term risk in semis contradicts the NVDA thesis. sending for review." In his work setup there is no cloud server, no team of analysts, and not even a Bloomberg subscription. At home sits a Mac Mini with a local Obsidian vault, on top run 6 N8N pipelines and a neural network analyst, and the same vault mirrors to a secure terminal on the iPhone. Out of everything I have seen this year, this is the cleanest solo trading setup on a second brain: $120 a month on the API, about $30,000 a month into the account, and between them 6 pipelines, 4,000 connected notes, and 1 iPhone in the pocket.show more

A STANFORD GUY POINTED CLAUDE CODE AT 11,400 OBSIDIAN... NOTES AND FOUND 214 ARGUMENTS HE'D HAD WITH HIMSELF 7 years of notes, 340MB of markdown, and a graph view that looked like a brain but never once thought. Every Sunday he opened the vault and every Sunday he closed it again. The second brain was a landfill with good lighting. So he stopped reading it and let something else read it instead. 47 lines of config, one instruction: find every pair of notes written 2+ years apart that contradict each other. 19 minutes on a 2021 MacBook Air, then 214 pairs. He had changed his mind 214 times in 7 years and caught himself doing it zero times. Then came the one that stopped him a note from March 2019, 62 words, sitting in a folder called "misc," describing the exact product he'd spent the last 5 months and $18,000 building a research doc around. He solved it in 2019, filed it, and forgot it existed. The vault never failed him, it stored all of it perfectly, it just had no way to speak. Now a cron job wakes at 6 AM, reads 40 notes, and writes 1 paragraph: here's what you believed then, here's what you believe now, here's the gap. He hasn't opened the graph view since. He didn't need a second brain, he needed the first one to answer back.show more
