Notion vs Obsidian is not really a features question, it is a question about who the notes are for and where they live. Notion keeps everything in its cloud as structured pages and databases, which is why it works for teams: shared wikis, project trackers, meeting notes linked to the project they belong to. Obsidian keeps everything as plain Markdown files on your own disk, which is why it works for individuals thinking over long periods: instant, offline, private, and readable in twenty years without the app. Choose Notion when other people need to see and edit the notes. Choose Obsidian when the notes are yours and you want to own the files. Running both is common and sensible.
Notion vs Obsidian: the real differences
| Axis | Notion | Obsidian |
|---|---|---|
| Where your notes live | In Notion's cloud database. You access them through Notion. | As Markdown files in a folder on your machine. Any text editor can open them. |
| Collaboration | Built for it. Shared workspaces, comments, permissions, real-time editing. | Single-player by default. Sharing means paid sync, a Git repository, or publishing. |
| Speed and offline | Needs a connection for most things. Noticeably slower on large pages. | Instant, always offline-capable. A large vault opens as fast as a small one. |
| How structure works | Databases with typed properties, relations and rollups. You define the schema. | Links and backlinks between files, with a graph view. Structure emerges rather than being declared. |
| Extending it | An official API and integrations with the tools your company uses. | Thousands of community plugins. Enormous power, and you maintain it. |
| Pricing shape | Free for personal use, per member for teams. | Free for personal use. Paid add-ons for sync and publishing, and a separate licence for commercial use. |
| Getting your data out | Export exists, but the result needs cleaning and databases lose their behaviour. | There is nothing to export. The files are already yours in an open format. |
Plan prices are left out on purpose here, since both vendors adjust tiers and add-on pricing. The structural difference, per-member billing versus per-feature add-ons, matters more than the current numbers.
When should you choose Notion?
- Other people have to read and edit. This is decisive. A team wiki, a client-facing document, an onboarding handbook. Obsidian can be made to do this, but you will be building the plumbing yourself.
- You want notes attached to structured data. A project page that is also a row in a database, with an owner, a status and a date, that appears in a filtered view somewhere else. This is what Notion is genuinely good at.
- Your teammates are not technical. Notion is learnable in an afternoon. Obsidian asks people to think about files, folders and Markdown syntax.
- You want one place instead of five. Meeting notes, roadmap, documentation and a light task tracker in one workspace removes a lot of small friction.
- You want it on any device without setup. Web, desktop and mobile with nothing to configure.
Where Notion objectively loses: speed, offline reliability and ownership. Large databases get sluggish, page-level permissions get awkward as a workspace grows, and everything you write is inside a service you do not control. If the company changed direction tomorrow, your archive would be a messy export.
When should you choose Obsidian?
- The notes are for thinking, not reporting. Research, writing, reading notes, personal knowledge built over years. Backlinks make connections you did not plan visible later.
- You want to own the files. Plain Markdown in a folder you control, backed up how you like, with no vendor between you and your own words.
- Privacy matters. Legal notes, medical notes, journals, client material under confidentiality. Local files never leave your machine unless you decide otherwise.
- You work offline or on the move. Trains, planes, unreliable connections. The vault does not care.
- Speed is a feature. Search across ten thousand notes returns instantly, which changes how often you actually search.
Where Obsidian objectively loses: collaboration, onboarding and maintenance. Sharing a vault with colleagues is not a solved problem. Mobile setup takes effort. And a vault held together by twenty-five community plugins is a small software project you now maintain, including the morning when an update breaks a plugin you depended on.
What do people miss when comparing Notion vs Obsidian?
- Lock-in is a cost you pay later. It never hurts in year one. It hurts in year four, when the workspace holds thousands of pages and the export produces a folder of files with broken links and databases that are now just tables. That is not a reason to avoid Notion, it is a reason to keep anything you would hate to lose in a portable format as well.
- Notion databases are not a database. They are excellent for hundreds of rows, workable for thousands, and painful beyond that. If you are building something that needs real queries, permissions per record or reliable performance, you are looking at the wrong tool.
- Plugin freedom is maintenance. Obsidian's community plugins are the best argument for it and the biggest ongoing cost. Install deliberately, keep the number low, and prefer plugins that only add convenience to files that would still make sense without them.
- Syncing is where Obsidian users get hurt. The official sync is paid and reliable. The free alternatives, cloud folders and Git repositories, work until two devices edit the same note and you spend an evening resolving conflicts. Choose the paid option or accept the maintenance.
- Using both is not indecision. A very common setup is Obsidian for personal thinking and drafts, Notion for anything the team touches. The rule that makes it work is simple: one tool owns each type of content, and you never keep the same document in both.
Once you have chosen, the hard part is the system
Both tools fail the same way. Someone sets up a beautiful structure in week one, then puts nothing in it, or puts everything in it with no naming convention, and six months later cannot find the note they know they wrote. The fix is a small set of rules: where a new note goes by default, how things get named, what gets archived, and what the weekly review actually checks.

Is Obsidian free?
Yes for personal use, with no limit on how many notes you keep. Sync and publishing are paid add-ons, and commercial use inside a company requires a separate licence. Budget for sync if you use more than one device.
Can Obsidian work for a team?
For a small technical team that is comfortable with a shared Git repository, yes. For anyone else, the effort of setting up sharing, permissions and conflict resolution outweighs the benefits, and Notion is the pragmatic answer.
Will my Notion notes work in Obsidian if I switch?
Text pages export to Markdown and land reasonably well after cleanup. Databases do not: they become static tables, and the relations, rollups and filtered views stop existing. If you think you might move one day, keep your important writing as pages rather than database entries.
Which one is better with AI?
Notion has AI built into the product, which is convenient for summarising and drafting inside a page. Obsidian relies on plugins, but has one structural advantage: your notes are plain files, so you can hand any of them to any assistant without an integration. See how to use Notion AI for the built-in side.
How does a skill file fit in?
It is a Markdown document you give to Claude that makes it work like a specialist, so the design conversation about your note system is with someone who has a method. It does not connect to either app. Setup takes about three minutes: how to install a Claude skill. Related roles sit in documentation and technical writing skills.
