Notion vs Obsidian in 2026 — I Used Both for 6 Months

Six months ago I committed to using both Notion and Obsidian every single day. Same projects, same notes, same workflows mirrored in both apps. I wanted to stop relying on Reddit arguments and figure out which one actually fits different types of work. The answer surprised me because it wasn't one or the other.

Quick Verdict

Notion is better for teams, project management, and shared documentation. Obsidian is better for personal knowledge, speed, and long-term note ownership. If you only pick one, ask yourself: "Do I mostly collaborate or mostly think alone?" That question answers it.

Price Comparison

Notion's free plan is generous for personal use. Unlimited pages, unlimited blocks. The Plus plan at $10/month adds file uploads over 5MB, 30-day page history, and guest access. Teams pay $18/member/month for the Business tier.

Obsidian is free. Period. The app costs nothing for personal use. If you want their Sync service (end-to-end encrypted, works across devices), that's $50/year. Their Publish feature for making notes public runs $96/year. But you can skip both and use iCloud, Google Drive, or Syncthing for free syncing.

Over a year, a Notion power user pays $120. An Obsidian user with Sync pays $50. Without Sync, $0. That gap matters if you're a student or freelancer watching every dollar.

Offline Support

Obsidian wins this one so hard it's almost unfair. Every note is a local .md file sitting on your hard drive. No internet, no problem. I wrote 40+ notes on a 6-hour flight without thinking about connectivity once.

Notion's offline mode has improved in 2026, but it still only caches pages you've recently opened. I lost edits twice during spotty hotel WiFi because Notion couldn't sync a conflict properly. The second time it duplicated a page instead of merging changes. Not acceptable for anything important.

Collaboration

Notion wins this category by a mile. Real-time editing, comments, @mentions, shared databases, permission controls per page, guest access. I ran a 4-person content team entirely in Notion for 3 months and it handled everything from editorial calendars to briefs to feedback loops.

Obsidian wasn't built for collaboration. You can share a vault via Git, but that requires everyone to understand Git. There's no real-time co-editing. No comments. No permissions. For solo work, this doesn't matter. For teams, it's a dealbreaker.

Customization and Plugins

Obsidian's plugin ecosystem is staggering. Over 1,800 community plugins as of mid-2026. I use Dataview (turns notes into queryable databases), Templater (dynamic templates), Calendar (visual daily notes), and Excalidraw (sketching inside notes). Each one is free and maintained by the community.

Notion has templates and recently added "automations" for basic triggers. It's nowhere close to what Obsidian offers. You can't change how Notion renders content. You can't add new block types. You can't build custom workflows beyond what their team ships. For people who like tweaking their tools, this gets frustrating fast.

Speed and Performance

Obsidian opens instantly. Switching between notes takes milliseconds. Search across 3,000+ notes returns results as I type. It feels like a native app because it basically is one, reading directly from your filesystem.

Notion has gotten faster in 2026 but there's still a perceptible delay when opening pages, especially databases with many entries. I timed it: a complex project board takes 1.5-2 seconds to fully load. Individual pages take 0.5-0.8 seconds. That adds up when you're jumping between 30 pages per hour during deep work.

Mobile Experience

Both apps work on iOS and Android. Notion's mobile app has slightly better UX for quick capture. The widget lets me add a note without opening the app. The interface is cleaner on small screens because Notion's block system translates well to mobile.

Obsidian's mobile app is functional but feels like a desktop app shrunk down. Editing long notes works fine. Navigation between many files can feel clunky compared to Notion's sidebar. If mobile is your primary input device, Notion has the edge. If mobile is just for reviewing and quick edits, both are fine.

Learning Curve

Notion is easier to start. You open it, you type, you drag blocks. Within 20 minutes you understand pages, databases, and views. The ceiling comes fast though. Complex formulas, relations between databases, and rollups get confusing quickly.

Obsidian has a steeper start. You need to understand vaults, linking with double brackets, and folder structure. The first hour is rougher. But the ceiling is much higher. After a month of learning, you can build a personal knowledge system that genuinely makes you smarter over time. Backlinks, graph view, and transclusion let you see connections you'd never notice in Notion.

Data Ownership

This is the category that made me move my personal notes to Obsidian permanently.

Obsidian notes are plain Markdown files on your computer. If Obsidian disappears tomorrow, your notes open in any text editor. They'll work in 20 years. You own them the way you own a paper notebook.

Notion stores everything on their servers. You can export to Markdown, but the export isn't perfect. Database views, toggles, and embedded content don't translate cleanly. If Notion changes their pricing, gets acquired, or shuts down, you're in a migration crunch. It probably won't happen. But "probably" isn't good enough for 5 years of accumulated knowledge.

My Recommendation by Use Case

Use Notion if: You work with a team, manage projects with multiple people, need shared documentation, want a quick-start tool without configuration, or run client-facing portals.

Use Obsidian if: You write daily, build a personal knowledge base, want your notes to outlive any company, value speed and offline access, or enjoy customizing your tools deeply.

Use both if: You're like me. Team stuff in Notion, personal brain in Obsidian. They don't compete when you split them by context. I stopped trying to make one app do everything and my system finally works.
