Don't use Obsidian for AI knowledge management: hand over all three jobs

What this episode covers

Whenever knowledge management comes up, it seems to mean installing Obsidian—and if you haven't, you look like you're not serious. This episode is about why that tool anxiety has expired.

I'm not going to trash it. Quite the opposite: I'll start with what it got right. A note app sells three jobs—store, maintain, view. It bet right on storage: plain text, file over app, your data is just your files. But that "friendliness" is the AI finding it friendly, not you finding it comfortable. Maintenance is something people cannot keep up: I'm an NTJ personality, J to the extreme, and I renamed every document by hand for over a decade without missing a day—and I still couldn't keep up. Viewing is the one reason it's still installed, and it's the job it does worst: my meeting notes, client proposals and research reports are all web pages or PDFs. Not one of them is md.

Give it credit first, then talk about the problem

Whenever knowledge management comes up, it seems to mean installing Obsidian—and if you haven’t, you look like you’re not serious. I call that tool anxiety.

I’m not going to call Obsidian worthless. Quite the opposite: I’ll start with what it got right. And once I do, you’ll notice something—the things it got right don’t need Obsidian to do them.

A note app, when you get down to it, sells three jobs: store, maintain, view.

Store: it bet right, but the upside goes to the AI

Plain text, file over app. Your data is just your files, not locked in any platform’s database, and you can take it with you when you switch tools. It bet beautifully here, and in the AI era that bet hasn’t aged—it appreciated, because plain text is the easiest thing for an AI to read and write.

But look closely. That “friendliness” is the AI finding it friendly, not you finding it comfortable.

So my verdict is one line: the format won, the software lost.

Maintain: people simply cannot keep this up

Backlinks, tags, MOC, the Zettelkasten card-box method. All of it amounts to making you your own librarian. You build the links by hand, you attach the tags by hand, and you keep feeding an index that only gets bigger.

People cannot do this. I’ll use myself as the sample: I’m an NTJ personality, J to the extreme. Every document since I started working was renamed by hand and uploaded to the cloud one at a time, for over a decade, without missing a day. But I could only keep up because I produced a few documents a day. Even someone as J as me would quit at dozens a day.

So this isn’t a discipline problem. It’s a human-nature problem, and maintenance has to be handed off.

Now the people who go deep will jump in: I already handed it off, I run Claudesidian and let the AI manage my vault. I agree with that—an AI manages Obsidian better than a person does. But go read its own documentation. It says right there that the Obsidian layer is optional, and that folder structure runs fine in an ordinary plain folder.

Which means: for the AI to do the managing, you don’t need the Obsidian layer at all.

View: the one reason it’s still here, and the job it does worst

By now the first two jobs are settled. Storage—the upside goes to the AI. Maintenance—the AI does it, without Obsidian. So what is that software still doing on your machine?

Only the third job: view. It gives you an interface so you can pull things up, use them, and look things over. That’s the one reason it’s still there. And here’s the problem—the one job it was kept for is the job it does worst. Two reasons.

First, md is deeply unfriendly to humans. I burn a few hundred million tokens a day now and produce over a hundred documents a day. At that volume I can’t be bothered to read a single line of md. Don’t jump on that—it doesn’t mean I read less. I read far more than before. I just don’t read md. It was born as a markup language for machines to read and write, so using it as a human reading surface never made sense.

Second, and this one is worse: what you actually work with isn’t only md. Every meeting note, client proposal and research report I have right now is a web page or a PDF. Not one of them is md. Obsidian either can’t handle those or handles them badly. The moment you most need to pull something up and reference it is precisely when it’s least helpful.

The conclusion: entirely redundant

Put those two together and the conclusion is sitting right there. The two jobs it’s good at don’t need it, and the one job left to it, it does badly. On that basis alone, Obsidian is entirely redundant.

What I actually need instead

Maintenance already went to the AI, so it generates the presentation layer along the way. I don’t want a fixed interface. I want something that manages itself: a multi-format viewer and editor, plus a filter-and-retrieval tool.

I’m not trying to open one document. I want to slice the whole pile by contacts, companies, projects, and life goals. How the relations get built and which documents to pull—the AI does all of that, not me.

I’m not the only one saying this. Karpathy’s LLM Wiki is even more direct: the knowledge base is handed to ClaudeCode to maintain and the human only reads. Maintenance is no longer something a person does.

How I actually manage my knowledge base now

One line: I manage it directly with ClaudeCode.

The page opens and 200-odd nodes lay themselves out into a Morandi-coloured starfield. Colour maps straight to file format, so at a glance you can tell which is a web page, a note, a spreadsheet, a slide deck. The bigger the dot, the more information it holds. Click any one of them and a floating window pops up with the file content right there—you can read it, and you can edit it.

The panel on the right is the slicing: contacts, organisations, projects, goals. Click one and the whole graph keeps only the related documents and re-clusters itself. That’s the retrieval tool I wanted—I never have to remember what a document was called.

The most interesting part is the edges. No human drew them. The AI inferred them, searching four levels down: explicit declarations in the document first, then topic membership, then in-body citations, and only then title similarity. So the backlinks of the AI era are written by the AI.

One more thing I love: I create a new file in the terminal, do no tidying at all, refresh the page, and the node grows in by itself. Filing is indexing.

Where did this starfield come from? An earlier episode covered letting the AI tidy local files and rename them automatically, and I open-sourced that. This starfield is the second half of the same job: renaming handles where a file sits, the starfield handles how files relate to each other.

How to build it: not complicated at all

  • Directory convention: finished pieces in one directory, notes by topic in another, all plain text
  • One iron rule written into CLAUDE.md: declare tags and relations the moment a document is created, not afterwards
  • Old documents need no page-by-page rework: one central registry table, one line governs a whole topic

A skill isn’t enough either

At this point you might think, fine, so what’s needed is a skill. But a skill isn’t enough—a skill is still passive. You have to call it.

I want something that moves on its own: an autonomous loop plus a scheduled job. It wakes up on time, sweeps the library, files new documents, fills in the relations, and flags what should be retired. By the time I want to look, it’s already there. The human isn’t in the process.

One step further: online documents are transitional too

Last episode I covered plugging AI into online documents. Now think about why online documents were valuable in the first place. Because an individual couldn’t stand up a platform—you had no way to build something that stored documents well, sent them to other people, and let everyone edit together. So we all had to get on somebody else’s platform.

With AI, that premise is gone. The AI manages the documents, the interface is generated on demand, and sharing means sending out a web page. So what’s left of the platform layer? What I think the future actually needs is some kind of A-to-A protocol, letting my AI talk directly to yours.

Which makes online documents a transitional form too.

What has to change isn’t the software. It’s who does the managing

Back to that tool anxiety. What you’re anxious about is not having installed the right software, but that’s not the real problem. The real problem is that those files of yours are still managed by you.

No software swap fixes that. What has to change is who does the managing. I’ve handed all of mine to ClaudeCode. So the question I asked at the very start no longer applies to me: I don’t go back and dig through my old notes any more. Whatever I ought to see gets delivered to me on its own.

The format won. The software lost.
