Obsidian and Notion are the two titans of the note-taking world, but they serve fundamentally different use cases. On Reddit, the r/ObsidianMD and r/Notion communities grow by roughly 5,000 members each per week. Yet the question remains: which one should you pick?
Reddit user u/notetakingnerd: "I've been switching back and forth for 2 years. The answer is: it depends on how you think. Notion is for organizers. Obsidian is for thinkers."

Real-World Speed Test Results
We tested both apps on a 2023 MacBook Pro (M2, 16GB RAM) with identical vaults of 500 markdown notes:
| Metric | Obsidian | Notion |
|---|---|---|
| Cold Start | 0.8s | 3.2s |
| Search 500 files | 0.05s | 1.1s |
| Open note | 0.02s | 0.4s |
| Render graph (200 nodes) | 0.3s | N/A |
Obsidian is dramatically faster across the board because everything is local. Notion's speed depends entirely on your internet connection.
Who Should Use Which?
- You are a developer, writer, or researcher → Obsidian. Local Markdown files, infinite customization, and fast as hell.
- You work in a team or manage projects → Notion. Real-time collaboration and databases are unmatched.
- You want a second brain (PKM) → Obsidian. The graph view and bidirectional linking are built for this.
- You need quick templates and don't want to tinker → Notion. It works out of the box.
- You care about data ownership → Obsidian. Your notes are plain Markdown files on your hard drive.
Frequently Asked Questions
❓ Can I migrate from Notion to Obsidian?
Yes. Export from Notion as Markdown, use the Notion Importer plugin in Obsidian. Expect to spend 1-2 hours cleaning up formatting.
❓ Is Obsidian really free?
Yes. The core app is free forever. You only pay for Sync ($5/mo) or Publish ($10/mo) if you need those features.
❓ Does Notion work offline?
Partially. It caches recently viewed pages, but you can't create or edit new content without an internet connection.
❓ Which has better mobile support?
Notion's mobile app is significantly better. Obsidian's mobile sync can be laggy unless you use their paid Sync service.
