Obsidian + Claude Code is how Andrej Karpathy turns 15 years of notes into a brain that works while he sleeps. The method behind it costs $0 and takes 5 minutes a day and it outlived every productivity app since 2011. Every idea, link, and half-thought gets appended to the top of a single note, with no sorting, no folders, no tags. Once a week he scrolls through, and anything that still matters gets copied back to the top. Weak ideas sink. Strong ideas resurface 5, 10, 20 times and by the 20th pass your brain has already wired them into everything else you know. Repetition as a filter. That's the whole system. Now the 2026 upgrade almost nobody is running: Drop that note into an Obsidian vault and open the folder with Claude Code not the chat app, the terminal agent that reads files. 3 commands change everything: read my last 30 days of notes and find the 3 ideas I keep circling without acting on link every note mentioning this project into a CLAUDE.md of what I actually believe about it draft this week's post from the idea that resurfaced most Claude Code doesn't search your vault it walks it, follows the wikilinks, and hands you the patterns you were too close to see. Karpathy method filters the signal, Obsidian stores it, Claude Code compounds it. One is a habit, one is a folder, one is $20 a month together they're the closest thing to a second brain that thinks back. Most people collect notes for 10 years and never read them once. His notes read him.

how to use obsidian + claude code to build a 24/7 personal operating system and build your startup: 1. write everything in markdown (daily notes, projects, beliefs, people, meetings) 2. link your notes together so they mirror how your brain actually thinks. 3. install obsidian cli so claude code can read your entire vault + the relationships. 4. stop reexplaining projects every session. use reference files instead. 5. build custom slash commands: /context → load your full life + work state /trace → see how an idea evolved over months /connect → bridge two domains you’ve been circling /ideas → generate startup ideas from your vault /graduate → promote daily thoughts into real assets 6. keep a strict rule: human writes the vault. agents read it, suggest, execute. 7. let claude aka clode surface patterns you’ve been unconsciously circling for years. 8. delegate from inside your notes. one sentence in obsidian → agent handles the rest. 9. treat writing as leverage.the more you write, the more context your agents have. 10. understand this:markdown files are the oxygen of llms. i really enjoyed seeing how to use obsidian thanks to internetVin vin uses ai like a thinking partner wired into his life’s work. 99.99% of people won’t do this because it requires reflection + setup. but once the vault exists, the agent stops being generic. it starts thinking in your voice. episode is live on The Startup Ideas Podcast (SIP) 🧃 (more there) this one is different. send this tweet to a friend. im still processing how game changer obsidian + claude code is, maybe you too watch

How did Atiq run the fake currency network? Dr. Vikram Singh, Former DGP of UP. Former UP DGP Dr Vikram Singh revealed in a podcast that Atiq Ahmed ran the fake currency network in the following manner: 🔴 The ISI had set up a factory in Bahawalpur, Pakistan, where the die machines of the Nashik Security Press, auctioned by Abdul Karim Telgi, were sent as scrap. 🔴 ISI, with the help of its sister agencies, procured raw material for counterfeit currency from Germany. 🔴 The fake notes reached Nepal via Nepal Pakistan International Airlines and then entered India via the UP-Nepal border (771 km, 7 districts: Pilibhit, Lakhimpur Kheri, Bahraich, Balrampur, Shravasti, Maharajganj). 🔴 Himalayan Bank was formed as a joint venture between Pakistan's Habib Bank and Nepal's National Bank. Its branches were opened on the UP-Nepal border to exchange fake and real currency notes. 🔴 Atiq did not print the notes himself, but he was a facilitator/sleeper cell of Ustrad – he provided manpower, logistics supply and protected umbrella. 🔴 Fake notes were mixed with real notes and real notes were mixed with fake notes (Exchange of 4 real notes and 4 fake notes in one branch) The former DGP said that Pakistan had injected fake currency worth around Rs 7-8 lakh crore into the Indian economy, and after demonetisation, people involved in this business in Pakistan committed suicide as all their assets became worthless.

A Stanford 26-year-old spent 2 years turning 11,400 Obsidian notes into a neural net that finishes his sentences. It started as a folder called “misc” with 43 PDF in it. Most vaults die around 300 notes, because nothing connects and nothing comes back roughly 90% of what you save gets read once, on the day you save it. He fixed it by treating retrieval as the product and storage as the leftovers. Phase 1: Atomize (months 1-3) One idea per note, 200 words max, title written as a claim instead of a topic. “Attention is a filter, not a spotlight” beats “Notes on attention.” He rewrote 1,200 old notes this way and the vault shrank from 2,800 files to 1,600 usable ones. Phase 2: Embed locally (months 4-8) Ollama running nomic-embed-text on a Mac Mini M4, every note chunked at 512 tokens with 64-token overlap, all of it dumped into a local ChromaDB. 11,400 notes became 38,000 vectors and 1.2 GB on disk. Query time 0.4 seconds, cost $0 a month, nothing leaving the machine. Phase 3: Kill the hallucinations (months 9-14) Plain cosine search returned garbage about 30% of the time, so he bolted on a re-ranker and one hard rule: every retrieved chunk carries its source note title into the answer, and no citation means no answer. Wrong recalls fell from 1 in 4 to 1 in 30. Phase 4: Make it speak first (months 15-24) A nightly job reads the day’s writing, pulls the 5 oldest notes with the highest similarity, and drops 3 questions into tomorrow’s daily note. He stopped searching the vault somewhere in month 17 now it opens the conversation before he does. Before: 2,800 notes, 0 reused, 6 weeks per paper draft. After: 11,400 notes, 60-70 surfaced every week unasked, 9 days per draft. The whole stack is 4 pieces Obsidian, Ollama, ChromaDB, and a 40-line Python script that runs at 2 AM. Total software spend across 24 months: $0. Most people build a second brain to store things they will never open again. He stopped writing to remember. He writes so the machine can remind him.

THIS GUY CONNECTED HIS AI AGENTS TO HIS OBSIDIAN AND BUILT A BRAIN THAT LEARNS ON ITS OWN. HERE'S HOW TO BUILD IT Obsidian is just markdown files sitting in a folder. That turns out to be the perfect memory for an AI agent, because an agent can read and write those files directly. He wired his agents into the vault so they pull context from it, do the work, and write what they learned back. The notes aren't the point. The loop is, and it gets sharper every cycle How to build it: 1. Point an agent at your vault. The fastest way, no plugins, no API keys: open a terminal and run npx obsidian-mcp /path/to/your/vault. That exposes your Obsidian folder to Claude as a tool it can read, search, and write to. Add it to your Claude Code or Cowork config and restart 2. Confirm it can see the brain. Ask it: "list the notes in my vault and summarize what's in them." If it reads them back, the connection is live. Now it starts every task with everything the vault already holds instead of from zero 3. Give each agent one job and a write-back rule. Tell it: "research this, then save what you found as a new note in /brain with links to related notes." One agent researches, one summarizes, one plans. Each writes its output back into the vault 4. Close the loop. Add one line to every agent's instructions: "read /brain before starting, write your result back when done." Now each task leaves the vault richer, and the next run reads that before it works. It compounds instead of resetting 5. You only steer. Review what the brain produces, point it at the next thing. The agents handle the reading, writing, and connecting The edge isn't better notes. It's a brain that feeds itself, so the work gets sharper every cycle instead of starting over Bookmark this

Obsidian + method Karpathy + Claude Code = a quantum second brain that talks back. Most second brains are graveyards you clip 300 articles, tag 80 notes, build a graph that looks like a galaxy, then never open it again. Karpathy fix is stupid simple: 1 file, append only, new thought on top, review by scrolling no folders, no tags, no 40-minute “PKM setup” videos. The capture layer is 1 Obsidian vault with 1 file called stream md, where every idea, quote and link lands in under 10 seconds, because anything slower and you quit by day 4. Once a week Claude Code reads the whole vault from the terminal with 1 prompt “find the 5 ideas I keep circling without noticing” and sees patterns across 6 months you can’t hold in working memory. Instead of searching keywords you ask questions like “what did I think about agent pricing in March,” and Claude greps 4,000 notes and quotes your own words back with file paths. Then the vault becomes context drafting a post, a pitch or a spec, Claude pulls in your past thinking instead of generic internet mush, and your output starts sounding like you, compressed. The first week feels pointless at 20 notes, month 1 brings the first “wait, I already solved this” moment, by month 3 Claude connects 2 notes written 70 days apart and that connection becomes your best post of the year, by month 6 you stop asking Google things you already answered. The whole setup costs $0 in software and 1 evening. Notion sells you a workspace, Obsidian gives you files, Claude gives them a voice. Everyone rents a second brain this one lives on your disk and grows. You wrote the notes, and now something finally reads them.

Obsidian just became the most dangerous folder on your computer, and Andrej Karpathy predicted it with 1 markdown file. His method is called append-and-review. He described it years ago and almost nobody listened: 1 single note, every thought appended to the top, reviewed on random scrolls. No tags, no folders, no Notion dashboards with 40 linked databases. The problem was always the same the note remembers, but it can't act. That changed the moment people pointed Claude Code at an Obsidian vault. Here's the setup that's quietly spreading: Part 1 — The vault becomes a database. Obsidian stores everything as plain markdown on your disk, which means Claude Code can read it like a codebase. You open a terminal inside the vault folder and your 2,000 notes turn into queryable memory. Part 2 — The CLAUDEmd file becomes the brain stem. One file at the root tells the agent who you are, what you're building, and how your notes are structured. From that point every session starts with full context instead of a blank chat window. Part 3 — Karpathy append log becomes fuel. You dump raw thoughts all day ideas, links, half-sentences. Then 1 command at night: review today's appends, extract action items, draft the 3 posts hiding in there, link them to existing notes. The messy log goes in, structured output comes out, and the vault rewrites itself while you sleep. Part 4 — Agents start living in your notes. People are running weekly reviews, content calendars, even market research as scheduled Claude Code runs over their vault. Your second brain stops being a graveyard of highlights and starts shipping. The honest math: setup takes about 90 minutes, the first week feels like overkill, and by day 30 you're sitting on a system where every note you've written in 5 years is working for you instead of rotting in a folder. Notion needed a server, a subscription and your data on someone else's machine. Obsidian needed a text file and now the text file has an employee.

The most valuable AI system you're not running yet: an AI second brain. The concept goes back to Karpathy's knowledge wiki earlier this year, and it's still one of the highest-leverage workflows in AI. Connect your Hermes agent, and it becomes 10x more powerful. Here's how to build it (from scratch): Step 1. Download Obsidian Head to obsidian.md and download the desktop app. Once downloaded, go ahead and create a new Obsidian vault. Vaults are just where notes/text are stored locally. Start dumping everything in here: - Personal goals - Meetings - AI context/preferences The more you put in, the more powerful your second-brain becomes. Step 2. Connect Hermes to your Obsidian vault If you don't have Hermes yet, download the desktop app here: [ Then, paste this prompt: "I want you to connect to my new Obsidian vault and act as my second-brain personal assistant - do everything necessary to set up that connection now." This gives Hermes direct access to everything inside your notes vault. Step 3. Let it self-evolve Every time you add a new note, Hermes will automatically ingest it. Prompt Hermes: "Every day, scan my second brain database. Every time I add a new note, use it to create reusable skills and workflows." Pro tip: Once Obsidian is connected to your agent, you can just prompt it directly to add notes/context/data. This works really well if you're prompting Hermes on the go from Telegram/mobile. Save this and build your second brain system now.

THIS GUY BUILT A BUSINESS SECOND BRAIN WITH CLAUDE CODE + OBSIDIAN IN 3 STEPS Most teams do not need another Notion workspace. They need a place where the company can remember how it works. The video shows a simple setup: 1. Create one empty folder called second brain. 2. Split it into 3 buckets: raw new knowledge wiki 3. Let Claude Code turn messy company material into connected notes. The useful part is the separation. Raw is where your existing stuff goes: SOPs, sales docs, process notes, client delivery checklists, old Loom summaries, onboarding docs. New knowledge is where fresh outside material lands: articles, clips, tactics, examples, market notes. Wiki is the cleaned version: concepts, roles, processes, SOPs, gaps, reusable decisions. That is where Claude Code becomes more useful than a normal chat window. Instead of asking it to remember random context forever, you give it a folder it can read, edit, and reorganize. Then Obsidian becomes the human interface. The Obsidian Web Clipper captures useful pages into the vault. Claude Code ingests them. The wiki gets updated. Then you can ask questions like: “Does my current workflow actually hold up?” That is the real point. Not “AI notes.” A business memory system that can compare what you do today against new information tomorrow. The caveat: this is not magic company intelligence. If your raw docs are vague, outdated, or full of tribal knowledge, Claude will organize weak inputs into cleaner weak outputs. You still need naming rules, review habits, and someone responsible for deleting junk. But the setup is refreshingly practical. Folder first. Clipper second. Claude Code as the maintainer. No giant knowledge base migration. No complex setup. Just a local vault that can slowly turn scattered business memory into something searchable, editable, and actually reusable.

PhD Students – How to convert your rough notes into a paper draft in 1 hour? Let’s first quickly understand the concept of rough notes. As a PhD student, you often read papers and make notes. Sometimes, you extract data from the papers you read. You record this data in an excel sheet. Irrespective of how you record your notes or data, you can convert it into a paper draft. More interesting, you can do this automatically. 𝐖𝐡𝐲 𝐭𝐨 𝐜𝐨𝐧𝐯𝐞𝐫𝐭 𝐲𝐨𝐮𝐫 𝐧𝐨𝐭𝐞𝐬 𝐢𝐧𝐭𝐨 𝐚 𝐩𝐚𝐩𝐞𝐫 𝐝𝐫𝐚𝐟𝐭? ➟ Difficult to comprehend your notes/data ➟ The notes are scattered in different places ➟ Need to synthesize a broader idea from your notes ➟ Need to write paper based on data noted 𝐇𝐨𝐰 𝐭𝐨 𝐜𝐨𝐧𝐯𝐞𝐫𝐭 𝐲𝐨𝐮𝐫 𝐧𝐨𝐭𝐞𝐬 𝐢𝐧𝐭𝐨 𝐚 𝐩𝐚𝐩𝐞𝐫 𝐝𝐫𝐚𝐟𝐭? 1. Go to and log in. 2. Open a blank document to start. 3. Click on 𝑊𝑟𝑖𝑡𝑒 on the right menu. 4. Click on 𝑢𝑝𝑙𝑜𝑎𝑑/𝑎𝑡𝑡𝑎𝑐ℎ button to upload your rough notes. 5. Use either pre-defined prompts or write your own. 6. For example, use the prompt – 𝐷𝑟𝑎𝑓𝑡 𝑎 𝑙𝑖𝑡𝑒𝑟𝑎𝑡𝑢𝑟𝑒 𝑟𝑒𝑣𝑖𝑒𝑤. 7. Paperpal will convert your notes a first draft of literature review. 8. Unlike ChatGPT, it will include real references your notes have. 9. You can give follow up instruction to modify the output. 10. For example, you can instruct – 𝑚𝑎𝑘𝑒 𝑜𝑢𝑡𝑝𝑢𝑡 𝑚𝑜𝑟𝑒 𝑐𝑜𝑛𝑐𝑖𝑠𝑒. 11. Paperpal will provide a concise alternative. 12. You can continue writing using the following options. ➝ Keep Writing ➝ Expand on ➝ Write a counter argument ➝ Write a transition sentence ➝ Write an impact statement 13. You can either accept or discard the generated text. Following this process will generate a paper draft for you. However, it is important to note that it is only a draft. You need to put your own human insight into it to polish it. You also need to carefully cross check the outputs. Please note this tutorial and tool is to facilitate you. It does not intend or even can replace you as a researcher. Try the Write 2.0 feature of Paperpal. Here is the link: Use code – FAHPP30 to get 30% off on Paperpal Prime. Anything you'd like to add?
