Quick Verdict

Notion if you want your notes to look pretty and live in the cloud with a team. Obsidian if you want to actually own your brain and don’t mind a learning curve that’ll make you question your life choices. I’ve used both for two years. I switched back once. I’m not proud of it.

Notion *** (3/5) — gorgeous, slow, and it wants you to pay for AI now Obsidian **** (4.5/5) — ugly duckling that turns into your entire second brain

I figured out I had a problem at 11:40pm on a Tuesday, sitting on my kitchen floor eating cold leftover pad thai because I couldn’t find a note I’d written three weeks earlier about a client’s brand colors. I had that note. I know I had that note. I just couldn’t remember if I’d put it in Notion, in a Google Doc, or in the Obsidian vault I’d abandoned two months prior because I got mad at the graph view.

That’s the whole thing, right? Personal knowledge management sounds like a productivity influencer’s wet dream until you’re eating cold noodles and questioning every system you’ve ever built.

So I did the mature thing. I picked one. Actually, I picked one, then picked the other, then picked the first one again. Here’s what happened.

Notion: the pretty one that’ll betray you

I went to Notion first because everyone does. It’s the default. Your friend who runs a "solopreneur" newsletter uses it. The templates are gorgeous. You can build a database that tracks your reading, your workouts, your mood, and your dog’s vet appointments in like 20 minutes. It’s genuinely fun.

The surprise — and I mean this — is how good the databases actually are. I built a project tracker with linked views and filtered rollups and felt like a genius. That feeling lasted about six weeks.

Then I hit 4,000-ish pages and Notion started… hitching. Typing lag. Images taking a full second to load. I’m on decent wifi. I tried the desktop app, which is just Electron with extra steps, and it was only marginally better.

Then they announced Notion AI. Cool. Except now the thing I pay $10/month for is shoving a "summarize this" button everywhere like a needy coworker.

Oh, and I once accidentally shared an entire client wiki with "anyone with the link" for three days before noticing. Three days. I found out because a client emailed asking why they could see my notes about their "aggressive" deadline requests. I wanted to die. That one’s on me, but Notion makes it so easy to do.

Obsidian: the one that made me feel dumb then made me feel smart

Obsidian scared me off the first time. I opened it, saw a blank vault, and immediately closed it and went back to Notion because there was no template gallery holding my hand. Big mistake. Huge.

Second attempt, I actually read the docs. Local markdown files. That’s it. Your notes are just .md files sitting in a folder on your hard drive. You can open them in TextEdit. You can sync them with iCloud, Dropbox, Git, whatever. Nobody can shut off the servers because there are no servers.

The plugin ecosystem is unhinged in the best way. I use Dataview to auto-generate lists from tags. I use the Kanban plugin. I use a plugin called "Homepage" that just opens a specific note when I launch the app, which sounds stupid until you use it and realize how much friction it saves.

It’s ugly out of the box. Genuinely ugly. You have to theme it. If you don’t want to spend a weekend tweaking CSS, you’re gonna have a bad time. And the mobile app? Sync costs $10/month and the free options (iCloud on iOS) are janky enough that I once lost four notes to a conflict resolution nightmare.

But nothing is locked in. Nothing. I can leave tomorrow and my notes come with me as plain text.

The parts nobody talks about

Notion’s support is… fine? I’ve emailed them twice. First response took nine days. Second took four. They were polite. They didn’t fix my problem.

Obsidian’s "support" is a forum and a Discord. If you’re not technical, this is a wall. If you are, it’s the best support you’ll ever get because the community actually built half the features Notion charges you for.

Hidden cost on both: your time. Notion tempts you into endlessly reorganizing. Obsidian tempts you into endlessly configuring plugins. Neither one is going to write your notes for you. That’s the part nobody wants to hear.

Also — Obsidian’s graph view is beautiful and functionally useless. I don’t care what anyone says. It looks like a constellation and tells you nothing.

What I Actually Use Now

Obsidian. Not even close, and I’m kind of annoyed about it because Notion is objectively prettier.

The reason is simple: I stopped trusting Notion with my brain. I’ve watched too many tools pivot, die, or get acquired and gutted. My notes are the one thing I don’t want to re-platform ever again. Markdown files in a folder I control is boring and that’s the entire point.

I still keep a Notion workspace for shared stuff — client docs, project boards with other people. It’s fine for that. Collaboration is where Notion wins and Obsidian doesn’t even try.

But my actual thinking? That lives in Obsidian. Warts and all.

Obsidian

Plain markdown files, fully portable, works offline forever
Plugin ecosystem is absurd in the best way

Ugly out of the box, heavy setup time
Sync costs $10/month or requires DIY solutions
Can become a tinkering hobby instead of a note-taking tool

FAQ

Q: Is Obsidian really free? A: Yes, for personal use. Commercial use technically asks you to pay. Sync is the paid part and it’s $10/month or $50/year, which is fine but annoying.

Q: Which one is better for students? A: Notion if you need to share notes with a study group. Obsidian if you’re writing a thesis and want everything searchable and offline.

Q: Can I use both? A: Yes, and a lot of people do. Just don’t expect them to talk to each other cleanly. You’ll be copy-pasting and hating yourself.

Q: Which is better for long-term knowledge management? A: Obsidian, full stop. Plain text outlives every app.
