testing Al Second Brain setups, sharing what actually works
Videos
i genuinely can't understand why this isn't the first thing every claude user builds... andrej karpathy, co-founder of openai, quietly solved the exact problem making your ai useless and almost nobody noticed here's the problem he solved... every session claude starts from zero, rereads the same files, forgets every contradiction it already caught, burns tokens relearning what it knew yesterday, forever 1. raw holds the truth once, wiki holds the compiled answer forever, instructions hold the one rule that stops it from ever getting messy again 2. claude opens a raw file exactly one time in its entire life, after that it only speaks in wiki pages with the sources already cited 3. the moment claude catches you contradicting yourself, it writes both versions into the wiki with dates, so it never asks you the same wrong question twice your raw files are disposable... the compiled wiki is the only thing that actually compounds full breakdown is in the article below

THE CREATOR OF OBSIDIAN JUST SHIPPED HIS OWN CLAUDE SKILLS PACK 44,000 developers already installed it. most people building second brains with claude have no idea it exists these aren't community skills. they're written by kepano himself - the person who built obsidian. that means they respect obsidian's actual conventions: markdown, bases, JSON canvas, backlinks, plugins, all of it drop them into your claude skills folder once. next time you say "summarize my notes about karpathy" or "extract this article to my inbox," the right skill wakes up automatically. no prompt engineering. no manual context. no config i tested 10 claude + obsidian repos to write my full breakdown. this is the one with the highest trust factor - because the person shipping it is the one who defined what an obsidian vault even looks like the full ranked breakdown of all 10 is in the article i test things like this on myself and share the results. follow kai if you want to see what's next

SOMEONE FROM THE ANTHROPIC TEAM LEAKED THEIR OBSIDIAN SETUP. 8 MILLION PEOPLE SAW HOW HE ACTUALLY USES CLAUDE the funniest part? all of this information was sitting in claude's documentation from day one. nobody read it one guy did, packed it into a 9-step guide and posted it. and it broke the internet. 4,100 likes, 800 retweets, then china picked it up and 8 million views want to know what's in it? one file. called CLAUDE.md. it holds everything about you: how you think, what you're working on, where you get stuck, even how you want the ai to talk to you. claude reads it first every single session one file changed everything. because now ai doesn't open with "how can i help?" it already knows. it remembers your projects, sees your goals, catches moments where you're contradicting yourself people spent years searching for the perfect prompt. the right temperature. the magic formula. and the answer turned out to be not how you ask ai. but what ai knows about you before you even open your mouth then the guy went deeper. taught claude to work on a schedule. every morning at 7am the ai walks through all notes on its own, finds new stuff, links it, cleans what's stale. no command. no reminder and all of this runs on obsidian. free app. text files on your drive. no cloud, no lock-in. switch models tomorrow and the folder keeps working the most liked comment under the original post: "this is the difference between using ai and building a system. most people won't realize it until they waste hundreds of hours repeating themselves" hundreds of hours. you've already spent some of them full guide in the video. i break down finds like this every day - follow so you don't miss the next one

i genuinely can't understand why this isn't the first thing every claude user builds... anthropic quietly shipped a folder system where claude loads specialized instructions on its own based on what you ask. no prompt engineering after setup. almost nobody uses it here's how it actually works... you drop a folder into your skills directory. inside: a SKILL.md that says "trigger this when the user asks about X". claude reads the description once at startup. next time you ask about X, it silently pulls in the whole skill - custom instructions, scripts, examples - like a specialist walking into the room 1. skill for your writing voice - loads only when you draft, never when you analyze 2. skill for your codebase conventions - loads only when you edit that repo, not others 3. skill for your accounting flow - loads only when you say invoice, receipt, or expense your context window stays empty until you need it. one claude behaves like 30 different specialists in one chat and you never manage the switching full breakdown in the article below i test things like this on myself and share the results. follow kai if you want to see what's next

ONE OF CLAUDE'S DEVELOPERS MESSAGED ME "YOU'RE USING AI AT 5%. LET ME SHOW YOU HOW WE ACTUALLY WORK WITH IT" we talked for 40 minutes. he shared his screen and showed me his obsidian. i expected some complex setup with code it was a folder. a regular folder with text files but when he opened the graph - i went silent. thousands of dots. thousands of lines. everything connected. everything alive. he says "this is my brain after 4 months. i didn't link a single note manually. claude did all of it" then he showed me something i still haven't recovered from he typed to claude "where am i contradicting myself?" claude thought for about 10 seconds and returned 4 pairs of notes where he wrote one thing and did another. with dates. quoting his own words back at him he laughed and said "see? no friend will ever tell you this. but this thing will and it won't get offended" i asked him to help me set it up. he walked me through it. took two evenings now my vault is on the video. it's still small. but it already knows my projects, my goals, my weak spots. and every morning it writes me a short brief: what changed, where i'm stuck, what i forgot the scariest part - i can't imagine working without it anymore. and just a month ago i thought this was too complicated for me i was wrong full guide on how to build this from scratch - article attached i test things like this on myself and share the results. follow kai if you want to see what's next

i simply can't get over how few people are actually doing this... Andrej Karpathy, co-founder of openai, basically described the whole setup and almost nobody built it let me break down what it actually does... every scattered note, every source you dumped somewhere and forgot, every pattern buried across hundreds of files... compiled once into something claude can scan in seconds instead of rereading cold every session 1. three folders, that's the whole vault: raw holds the originals untouched, wiki holds what claude compiles from them, instructions holds the rules for how it compiles 2. claude reads raw/ once, turns each source into linked wiki pages with sources cited, never opens the raw files again after that 3. every contradiction gets flagged right inside the wiki with both sides and dates, every future session reads the flag first, so you catch it once instead of forever the raw files are disposable... the wiki is what actually holds the value full breakdown is in the article below

i keep telling people to build this and they nod politely and never do it... andrej karpathy posted how to fix this a while ago, and everyone just keeps working the old way the dumb thing is this... you pay to teach claude the same lessons over and over, every chat is a fresh amnesia patient, every contradiction it catches evaporates the second you close the tab, and you accept this like it's just how ai works 1. one folder is a graveyard for originals that nobody edits, another folder is claude's active memory that only claude writes to, a third folder is a two-page rulebook that keeps claude from confusing them 2. a raw file gets read the day it arrives and then it's done, claude never touches it again, everything it needed is already extracted into wiki pages with the source cited right there 3. every time claude notices your new answer clashes with your old one, it doesn't pick a side, it writes both with dates, and from then on it treats you like someone who might be wrong the raw folder is a museum... the wiki is the actual working brain full breakdown is in the article below

AN ANTHROPIC ENGINEER LEAKED THIS OBSIDIAN CONVENTION you start with 12 notes and one convention. 6 months later you have 2379 and every one is linked to every one it belongs next to. you never touched the graph. claude did the convention is a domain prefix at the top of every markdown file. six characters. claude reads it, knows where the note belongs, and connects it to the older ones without you ever asking you drop in a new pdf at midnight. claude reads it, writes 8 linked notes, contradicts your old note from march, dates both versions, and pins the one you actually need on top by morning your vault stops being a folder. it becomes a night sky article in the first reply i test things like this on myself and share the results. follow kai if you want to see what's next
