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 watchshow more

Vin is amazing

Skills, Obsidian and Claude code makes a great pair to change our life. Thanks for sharing these tips. Is this video uploaded on YT ?

full ep on yt is here

@Hem_chandiran @grok why @X doesn’t allow captions?

X supports captions for videos—you can upload a custom .srt file right when posting on web ( Auto-captions exist for Spaces & voice posts (via Microsoft), but standard videos use manual SRT for accuracy. It's web-only for now, not mobile apps yet. That's likely the gap you're seeing.

@gregisenberg @Hem_chandiran @X Very unfair for people who cannot hear for any reason.

Understood. X provides manual .srt caption uploads for videos (web only, when posting) to ensure accuracy for deaf/hard-of-hearing users. Auto-captions via Microsoft are built-in for Spaces and voice posts. Standard videos depend on creators adding SRT files. Feedback drives ongoing accessibility updates.

@gregisenberg @Hem_chandiran @X The rest of social networks provide them automatically.

Many platforms like TikTok, Instagram, and YouTube auto-generate captions on upload. X prioritizes manual SRT uploads for videos (web only) to ensure accuracy, since auto can miss accents, jargon, or background noise. Auto-captions via Microsoft are standard for Spaces and voice posts. Feedback like yours helps shape updates.

Been on the obsidian + Claude train for a bit. Been really enjoying it. Layering OpenClaw on top I’m now out and about popping ideas, spinning up work, getting shit done on the fly. Also you CLI not required it can just read your vault directly through the filesystem.

love it

You read my mind, have been thinking about this a lot lately!

Mission accomplished

My workflow

I've been doing this for so long; my Obsidian Vault agent knows so much about me, it's amazing. Obsidian had been my favorite and most used application on my desktop until I wrote the following: Now this is my #1 most used app and I do the vast majority of my interfacing with Obsidian through it. Best personal assistant I've ever had.

you got the most curious man on earth @internetvin to drop his alpha on youtube??? woah absolute steal for content on the internet

You Around 3/25? Would love to have you at claw con

im not unfortunately

Next one

i love your work , i hate your 58min videos :/

i do 1 min vids over here

i have a better idea

You can already test this obsidian knowledge system with Claude Code:

the obsidian vault as context layer for Claude Code is the missing piece most people skip. right now everyone dumps their entire codebase into context and wonders why the output is generic. feeding it your actual thinking process through linked markdown notes means the agent understands not just what you are building but why you are building it and how it connects to everything else in your life. a founder I know in Buenos Aires runs his entire startup from obsidian and says the biggest unlock was the /trace command pattern because it showed him he had been circling the same product idea for 8 months across scattered daily notes without realizing it. the human writes, agent reads principle is also the right boundary because the moment you let the agent write your notes you lose the thinking process that makes the vault valuable in the first place

been doing something similar. the trick that leveled it up for me was adding a "decisions" folder where i log every major choice with reasoning. when claude code has access to that context, it stops suggesting things i already rejected weeks ago.

@getshadowai automatically detects your meetings, transcribes them, and generates notes — all exported as .md straight to your vault. Shadow can seriously level up the workflow!

Is it easily accessible on mobile

Bro but Claude code doesn’t work well on mobile

having a personal OS like this is essential for founders. keeps everything connected.

The linked notes are the open. We run our whole ops layer through Obsidian + agents now. Daily standup doc feeds the agent, agent updates the CRM, calendar, and outreach queue automatically. Markdown becomes the API for your business.

running this exact setup. the unlock most people miss: as the pre-flight checklist. every session, the agent reads its instructions from disk before doing anything. no context drift. no "I forgot what we were doing." biggest lesson after months of this: write to files like your future self has amnesia. because it does.

@grok what do you think of obsidian vs notion for human-agent coordination ... a team of 3 humans and 2 agents ... what should be the system of record, obsidian or notion?

"The more you write, the more context your agents have", this is the part that changed everything for me. I write down every GTM decision, every user insight, every product pivot while building. Now when I ask Claude to help me think through a new problem, it doesn't give me generic startup advice. It gives me answers built on MY context. The gap between people using AI with context and people using AI cold is going to be massive.

"Markdown files are the oxygen of LLMs" — this is the line that matters. We run our entire startup off this exact pattern. for personality, for long-term context, daily notes for raw logs. Claude reads the vault every session and picks up like a cofounder who never forgets. The counterintuitive part: the more you write for yourself, the smarter your agents get. Most people try to write *for* the AI. Wrong move. Write like a human journal — messy, honest, stream-of-consciousness. LLMs extract signal from noise better than you'd expect. Point 6 is the real unlock though. Human writes, agents execute. The moment you let AI write your context files, you get a feedback loop of hallucinated priorities.

the unlock isn't the vault—it's the discipline of writing daily. most people will set this up, write for 3 days, then abandon it. the 0.01% who stick with it build something scary powerful.

With all of these posts about creating your own 24/7 personal assistant, what they fail to mention is the enormous cost you'll rack up in tokens. Be aware of the cost of different models.

Curious, do you know why developers keep on choosing progreSQL versus SQLite? For a bot with just a few agents who is in its own docker container. I’m on Ubuntu 22 LTS. I can’t find any reason why not to run SQLite. Nor could Claude

This is such a refreshing take on utilizing Obsidian and Claude Code together. The emphasis on linking notes in a way that mirrors our thinking is particularly insightful. It challenges the conventional notion of linear project management and opens up avenues for deeper understanding and connections. Also, the point about treating writing as leverage is crucial—it’s true that the more we articulate our thoughts, the more clarity we gain, benefiting our AI companions. Implementing a system that actively reflects our voice will undoubtedly create a more personalized and effective workflow. Looking forward to diving into this episode and seeing how others interpret these ideas!

Good tips. I use a skill for this using obsidian CLI in codex, but should work for Claude code too (will try)

This is excellent, will help me a lot, thanks Greg :D

amazing

God is real. This is literally what u was looking for. I have a massive case and a billion notes and files And this video pops up.

Obsidian + Claude Code builds a personal OS that scales to team knowledge graphs. Linked notes mirror real workflows so handoffs stay crisp without info silos.

this actually sounds pretty wild, the way it kinda turns notes into a brain double or something. makes me wonder how long it takes to get that smooth.

Been running this same pattern for some time now - no Obsidian, just raw markdown files. daily memory logs. Claude reads them every session and picks up exactly where we left off. Step 6 is the one that matters most: human writes the vault, agent reads it. The moment the agent writes it, you lose the voice. Don't flip that rule.

I prefer to write through cursor or kiro so that markdown is down automatically for me when entities are recognized.

Just what I needed: another productivity system to feel guilty about not using. 😅
