Your Brain Has a Terrible Search Function
Obsidian convinced me to take notes again. Not just for work, for everything.
I stopped taking notes after university. Not because I stopped learning, but because school was the context that made note-taking feel necessary. Class had a fixed endpoint. There was an exam coming. You had a reason to capture things.
After graduation, that structure disappears. You learn at work, you learn from reading, you pick things up from conversations and documentation and debugging sessions. And where does it all go? Into your head. Somewhere in there, compressed, fuzzy, retrievable only if you can find the right association to trigger it. The hard-won knowledge that took you years to accumulate degrades into “I know this, I just need to look it up again.”
That’s a terrible system. Obsidian is a better one.
It’s Just Files
The reason I trust Obsidian with my notes is the simplest possible one: your notes are just Markdown files on disk. No proprietary format. No database. No export process required to get your own data. You open your file browser, your notes are right there, readable by any text editor that’s existed in the last 40 years.
This matters because note-taking apps have a history of dying, pivoting, getting acquired, or adding paywalls after the fact. Evernote had a rough run. Notion is great until it isn’t. When your notes are plain Markdown, you can walk away from any tool and your data comes with you. There’s no lock-in because there’s nothing to be locked into.
Sync on Your Terms
Since the notes are just files, you can treat them like any other project. Some people keep their vault in a git repo, push to a private remote, and get free version-controlled sync with no third party involved. That’s a completely valid setup.
I use Obsidian Sync. Having my notes show up instantly on my phone and every other device without thinking about it is worth the price. The Obsidian team is small, they’ve built something genuinely good, and they’ve been profitable doing it. That’s worth supporting.
And if I ever cancel, my notes are still my files. Nothing changes except the convenience.
The Plugin Ecosystem Is Enormous
The community plugin list is massive. Calendar views, kanban boards, spaced repetition for flashcards, graph visualizations of your linked notes, Dataview (which lets you query your notes like a database), templating systems, daily note workflows, integrations with anything you can think of. There’s a plugin for almost every workflow pattern someone has tried to build inside Obsidian.
The fact that the community has built all of this on top of plain Markdown files is a testament to how solid the foundation is.
The ones I actually use: Excalidraw for freehand diagrams and visual thinking directly inside a note, and Folder Notes paired with Waypoint for a wiki-style structure where folders have their own index note that auto-links everything inside them. None of these are flashy. All of them fill a real gap.
The Second Brain Thing
The pitch for Obsidian, if you’ve spent any time in the productivity rabbit hole, is the second brain concept. The idea that your notes shouldn’t just be a dump of things you need to remember, but an interconnected graph of ideas you can actually think with. Linked notes, backlinks, the graph view showing how your knowledge connects.
I’m not going to pretend I have some perfectly organized system. I don’t. But the underlying idea resonates: your notes should extend your thinking, not just archive it.
And here’s the part that really clicked for me: this extends way beyond work.
I have notes on shows I want to watch. Recipes I’ve tried and want to remember. Personal philosophy and my own code of ethics. Thoughts I had about something that happened, written down while they were still fresh. Goals. Ideas that need somewhere to live. Stuff that doesn’t fit anywhere but deserves to exist somewhere outside my skull.
The notes from my CS degree are in there too. Concepts I understood deeply once and now only half-remember. Things I can rebuild faster by finding the note than by re-learning from scratch.
It’s not just a productivity tool. It’s an extension of memory. Which is a weird thing to say about software, but it’s the most honest description I have.
Start Somewhere
Open the app, make a vault, start writing. You don’t need a system. You don’t need to set up Dataview or watch productivity YouTube before you’re allowed to begin. Just start putting things in there that you want to remember.
The structure develops on its own as you figure out what you actually need. The important thing is that the notes exist, they’re yours, and they’ll be there in ten years in the same format they’re in today.
That’s more than most apps can promise.
If any of this resonates, the video that started it for me was Hack your brain with Obsidian.md by Tris from No Boilerplate. Worth the watch.
