Files you own vs a workspace that does everything.
Obsidian vs Notion (or Notion vs Obsidian — the search works both ways) is really a choice between two philosophies. Obsidian is a local-first editor: your notes are plain markdown files on your disk, private and yours forever, organized entirely by you. Notion is a cloud workspace: docs, databases, and projects in one polished app, organized with structure Notion provides. Here's the honest breakdown — and where a third option fits.

Quick answer
Choose Obsidian for a personal knowledge base you fully own: local markdown files, offline by default, endlessly customizable with plugins. Choose Notion for team docs, databases, and project management in one easy cloud app. If your real problem is that neither maintains the knowledge base for you, that's the gap Mana targets — covered at the end.
| Obsidian | Notion | |
|---|---|---|
| What it is | Local-first markdown knowledge-base editor | All-in-one cloud workspace: docs, databases, projects |
| Where your data lives | Plain markdown files in a folder on your disk | Notion's cloud, in Notion's block format |
| Offline | Fully offline by default; sync is optional | Cloud-first; offline on desktop/mobile apps for pages you enable |
| Databases & projects | Via community plugins (e.g. Dataview, Kanban) | Native: relations, rollups, views, calendars, forms |
| Collaboration | Built for one person; sharing takes workarounds | Real-time multi-user collaboration, comments, permissions |
| AI | No built-in AI; added via community plugins you configure | Notion AI built in; AI Core included on Business/Enterprise, limited trials below |
| Extensibility | Thousands of community plugins and themes | Integrations, API, templates, marketplace agents |
| Getting data out | Nothing to export — the files are already yours | Manual export: markdown for pages, CSV for databases; some blocks export as HTML |
| Price | Free core app; Sync and Publish are paid add-ons | Free personal plan; paid per-user tiers for teams and Notion AI Core |
Obsidian people accept that they are the librarian: every link, merge, and cleanup is manual work, and vaults quietly rot when life gets busy. Notion people accept that their knowledge lives in someone else's cloud and format: export gives you markdown and CSV files, but relations, views, and structure degrade on the way out.
Mana takes Obsidian's answer to ownership — plain markdown, full history, no lock-in — and Notion's answer to convenience, by making an AI agent the librarian.
To be clear about what Mana is not: it's a paid hosted service in early access — not free, not open source, not self-hosted, and not a team workspace. Full head-to-heads: Mana vs Obsidian and Mana vs Notion.
Use Obsidian if you want a private, offline, plain-file second brain that you organize yourself and can keep forever. Use Notion if you want an easy all-in-one workspace with databases, project tools, and team collaboration, and you're comfortable with your data living in Notion's cloud.
Yes — the core Obsidian app is free for personal and commercial use. The optional Sync (device syncing) and Publish (hosted website) services are paid add-ons.
Yes. Notion exports pages as markdown and databases as CSV, and Obsidian has an official importer. Plain text and links transfer well; database relations, views, formulas, and permissions don't survive the trip.
That gap is exactly what Mana targets: your knowledge base stays plain markdown with git history in a GitHub repo you own (like Obsidian), but an AI agent does the organizing — reading sources, writing linked and cited pages, and committing every change for review (the convenience people love Notion for). Mana is a paid hosted service in early access.

Mana keeps your knowledge in markdown and git like Obsidian, and does the organizing for you like Notion never quite did. See a real ingestion on the use-case pages, then grab an early-access spot.
