Notion and Obsidian represent two fundamentally different approaches to note-taking. Notion is a cloud-first workspace with databases, collaboration, and AI. Obsidian is a local-first markdown editor with a plugin community and no vendor lock-in. The choice depends on how you think about your notes — and whether you want to own your data.
Quick Pricing Comparison
| Plan | Notion | Obsidian |
|---|---|---|
| Personal (Free) | Unlimited pages (block limits) | Completely free (local files) |
| Personal (Paid) | $10/user/mo (Plus) | $0 (free forever) |
| Sync service | Included in all plans | $4/mo (Obsidian Sync) |
| Publish/sharing | Included (one-click) | $8/mo (Obsidian Publish) |
| AI features | $10/user/mo add-on | Free plugins (local LLM or API key) |
| Commercial use | Free plan OK | $50/user/year (commercial license) |
Obsidian is free for personal use with no limits. Notion is free with block limits that push you toward the $10/month Plus plan. For teams, Notion charges per user; Obsidian doesn’t have native team features — you’d build your own workflow with Git or shared folders.
Notion Pricing Breakdown
Notion’s free plan works for light personal use but the block limit pushes power users to Plus within a few months. The AI add-on ($10/user/month) doubles your cost if you want Notion’s writing assistant, autofill, and Q&A features.
Notion’s Total Cost (Individual with AI)
Plus ($10) + AI ($10) = $20/month or $240/year. That’s real money for a note-taking tool, especially when Obsidian’s equivalent setup costs $48/year (Sync only) or $0 if you use iCloud/Dropbox for sync.
Obsidian Pricing Breakdown
Obsidian’s core app is completely free with no feature restrictions. Sync ($4/month) and Publish ($8/month) are the only paid services. Both are optional — you can sync via iCloud, Dropbox, or Git for free, and publish using other tools.
Obsidian’s True Cost
| Setup | Monthly Cost | Annual Cost |
|---|---|---|
| Obsidian only (local, no sync) | $0 | $0 |
| Obsidian + free sync (iCloud/Dropbox) | $0 | $0 |
| Obsidian + official Sync | $4 | $48 |
| Obsidian + Sync + Publish | $12 | $144 |
| Obsidian commercial license | $4.17 | $50 |
Philosophy Differences
This isn’t just a pricing comparison — it’s a philosophical one.
Notion: The Connected Workspace
Notion treats notes as one part of a larger workspace. Your notes live alongside databases, project boards, wikis, and team documentation. Everything is connected, searchable, and shareable. The trade-off: your data lives on Notion’s servers, and exporting to another tool loses databases, relations, and formulas.
Obsidian: The Personal Knowledge Base
Obsidian treats notes as plain text markdown files on your computer. You own them completely. They’ll be readable in 50 years regardless of whether Obsidian exists. The plugin system adds functionality (kanban boards, calendars, dataview queries), but at its core, Obsidian is a powerful text editor with linked thinking.
Feature Comparison
| Feature | Notion | Obsidian |
|---|---|---|
| Data storage | Cloud (Notion servers) | Local files (your device) |
| File format | Proprietary blocks | Plain markdown (.md) |
| Offline access | Yes (desktop/mobile) | Full (always local) |
| Real-time collaboration | Yes (multiple cursors) | Limited (via Sync shared vaults) |
| Databases | Yes (tables, boards, galleries) | Via plugin (Dataview) |
| Backlinks/graph view | Basic backlinks | Advanced (graph view, local graph) |
| Templates | 10,000+ community | Community + Templater plugin |
| AI features | $10/user add-on | Free plugins (bring your API key) |
| Plugins/extensions | Limited (integrations) | 1,600+ community plugins |
| Mobile app | Good | Good |
| Search speed | Good (server-side) | Instant (local index) |
| Data portability | Low (export loses structure) | Perfect (plain text files) |
| Team collaboration | Excellent | Minimal |
| API | REST API | Plugin API |
| Learning curve | Low | Medium |
AI Features: Different Approaches
Notion AI costs $10/user/month and offers: AI writing assistant, auto-fill databases, Q&A across your workspace, and AI-generated summaries. It’s integrated into the editor and requires no setup.
Obsidian’s AI is plugin-based. The “Smart Connections” and “Copilot” plugins let you connect your own OpenAI, Claude, or local LLM API key. You pay the API provider directly (typically $1–$5/month for personal use) instead of $10/month to Notion. The setup takes 10 minutes but costs 50–90% less.
Cost Comparison: Individual User
| Setup | Notion | Obsidian |
|---|---|---|
| Basic notes + sync | $0–$10/mo | $0–$4/mo |
| Notes + sync + AI | $20/mo ($240/yr) | $4–$7/mo ($48–$84/yr) |
| Full featured | $20/mo ($240/yr) | $12/mo ($144/yr) |
Obsidian with all paid services (Sync + Publish) and AI via API costs $144–$180/year. Notion with AI costs $240/year. Obsidian saves $60–$96/year while giving you full data ownership.
Cost Comparison: 20-Person Team
| Setup | Notion Plus | Obsidian (not designed for teams) |
|---|---|---|
| Monthly | $200/mo | $83/mo (commercial license) + sync solution |
| With AI | $400/mo | N/A (individual plugins) |
For teams, Notion is the clear choice. Obsidian wasn’t built for team collaboration. You can make it work with shared vaults or Git, but real-time editing, permissions, and guest access are Notion’s strengths.
Who Should Pick What
Pick Notion If:
- You need team collaboration with real-time editing and permissions
- Databases (CRM, task boards, content calendars) are part of your workflow
- You want an all-in-one workspace, not just notes
- Setup simplicity matters — Notion works out of the box with zero configuration
- You’re building a company wiki or knowledge base
Pick Obsidian If:
- Data ownership matters — your notes should survive any company’s shutdown
- You think in linked notes and want a knowledge graph
- You prefer customization through plugins over built-in features
- Privacy is a priority — notes never leave your device unless you choose to sync them
- You’re primarily a solo writer, researcher, or student
- You want AI features without paying $10/month to a SaaS provider
Best for teams: Notion — real-time collaboration, databases, and permissions make it the only viable choice for team knowledge management.
Best for individuals: Obsidian — free, private, and customizable. Your notes in plain text files that you’ll be able to read in 30 years.
Best value: Obsidian — $0 for the full app, $48/year for Sync. Notion costs $120–$240/year for comparable functionality.
Best for linked thinking: Obsidian — the graph view, backlinks, and plugin library (Dataview, Templater, Excalidraw) create a personal knowledge system that Notion can’t match.
Best for simplicity: Notion — zero setup, zero plugins, zero configuration. Open it and start writing.
FAQ
Can I migrate from Notion to Obsidian?
Yes. Export your Notion workspace as Markdown+CSV. The “Importer” community plugin handles the conversion. Databases export as CSV files that need manual reorganization. Budget 1–2 hours for a typical personal workspace.
Is Obsidian safe for sensitive notes?
Your notes are as safe as your device’s file system. They’re stored locally and never uploaded unless you choose Obsidian Sync (end-to-end encrypted) or a third-party cloud sync. For maximum privacy, keep notes local only.
Can Obsidian handle databases like Notion?
The Dataview plugin turns YAML frontmatter in your notes into queryable data — similar to databases but text-based. It handles simple task tracking and content catalogs well. For complex relational databases, Notion is better suited.
Does Notion work offline?
Yes, but with caveats. The desktop and mobile apps cache recent pages for offline access. However, you can’t access pages you haven’t recently opened, and sync can conflict when reconnecting. Obsidian works fully offline by design — every note is always available.
