The Setup: Why I Decided to Blow Up My System
I spent three years as a Notion zealot. Capital N, full commitment. My workspace looked like a Pinterest board had a baby with a spreadsheet—databases linked to databases, relations humming along, templates for everything from book reviews to quarterly planning. Then one Tuesday in October, I lost 20 minutes of notes to a sync glitch. Not permanently. Just temporarily. But that temporary loss cracked something open in my brain.
I realized I’d never actually tested whether Notion was the best tool for me, or just the most impressive one. So I did something genuinely unhinged: I set up Obsidian at the same time and committed to using both for 90 days. No transition period. No gradual migration. Just immediate, chaotic coexistence.
Before you ask why, know this: I’m not recommending this to everyone. But the debris from that experiment taught me more about my actual working style than three years of optimization ever did.
The Real Cost: It’s Not Just About Money
Let’s talk pricing first, because it’s surprisingly tangled. A fully featured Notion setup with their AI capabilities will run you roughly $20 to $25 per month if you’re on their paid plan with the AI add-on stacked on top. Obsidian’s local sync is $10 per month. Combined, you’re looking at $28 to $35 monthly if you want the real powerhouse versions of both. That’s not cheap. That’s a good coffee subscription for your brain.
But here’s what nobody tells you: the real cost isn’t the money. It’s the context switching. Running two systems simultaneously means you’re constantly asking yourself: where did I put this? Which tool handles this type of work better? Should I be duplicating across both, or maintaining separate spheres? I burned roughly four hours a week in those early months just managing the meta-problem of having two systems.
The weird part? That inefficiency was actually valuable. Because once you feel that friction viscerally, you stop theorizing and start deciding. You start to see which tool genuinely fits which part of your brain.
What Each Tool Is Actually Best At (Spoiler: They’re Not Competitors)
Here’s the thing that hit me hardest: Notion and Obsidian aren’t actually trying to solve the same problem. They just look like they are on the surface. Notion hit over 100 million users in 2024 for a reason. It’s an all-in-one workspace. They’ve pushed hard into AI, launching capabilities that can browse your databases and draft entire documents without you writing a single prompt. Notion AI features overview shows you the actual extent of this—it’s genuinely autonomous in ways that feel almost creepy.
But Obsidian? Obsidian is a fundamentalist about one thing: your data lives on your device. All of it. Plain markdown files. No proprietary format. No cloud vendor lock-in. Obsidian official documentation and pricing makes this crystal clear in every product decision. It’s not trying to be everything. It’s trying to be the safest, most portable home for your thoughts.
What shifted for me was realizing that Notion is best for coordinated work—the kind where you need databases talking to databases, where sharing and collaboration matter, where you want AI to help you synthesize and draft. Obsidian is best for thinking—the kind where you need zero friction between thought and capture, where you want your notes to belong fully to you, where you need to move between ideas at the speed of your mind.
The Weird Data: You Probably Want Both Too
Here’s the thing that made me stop feeling crazy about the dual setup: I’m not alone. A 2025 survey of over 3,100 knowledge workers found that 41 percent are now using two or more note-taking systems simultaneously. That number was 27 percent just three years ago. The debate about which tool is objectively better? It’s dead because the market figured out that it was a false choice.
People aren’t switching from Notion to Obsidian or vice versa. They’re using them for different jobs. There’s actual research backing this up too. When people ranked tools on data ownership and control in 2024, Obsidian ranked number one on Hacker News specifically because it stores everything locally on your device. That matters to a lot of people. Meanwhile, Notion kept growing because the cloud-based, collaborative, AI-augmented approach matters to different people in different ways.
The rumor mill around enterprise consolidation doesn’t change this either. Early 2025 brought speculation about larger players acquiring some of the local-first competitors, which made people nervous. But that nervousness actually proved the point: people care deeply about where their information lives and who controls it.
What I Actually Use Them For Now
After the 90 days, I didn’t pick a winner. I picked a job distribution. Notion is now where I process work that’s collaborative or needs real-time input from others. CRM-style tracking of projects. Databases where relationships between information matter more than the information itself. Places where I want AI drafting a first pass because I’m generating lots of output and need a speed boost.
Obsidian is where my actual thinking lives. Book notes. Long-form writing. The personal knowledge base that’s genuinely just for me. The stuff I want to still be able to read in 20 years, formatted as plain text, living on my hard drive. It’s slower to set up. It’s more friction. And that friction keeps me honest about what actually deserves to live there.
The chaos of running both taught me that productivity systems fail when you’re trying to cram incompatible needs into a single tool. Notion trying to be local-first would just be Notion again. Obsidian trying to be collaborative would be a worse version of Notion. The system works because they’re unapologetic about what they’re designed to do.
If you’re still stuck in the either-or mindset, I’m genuinely curious what problem you’re actually trying to solve. Are you trying to collaborate with others, or thinking alone? Do you need historical permanence, or rapid synthesis? Are you building a shared resource or a personal one? The tool question usually resolves itself once you answer that first. What’s your answer?
