Notion vs Obsidian (2026): Which Note App Should You Use?

Obsidian wins for pure note-taking: the app is free with no limits, notes save to your own disk as plain text, and the only charges are optional add-ons, $4 to $10 a month for sync or publishing. Notion wins once notes live inside a shared workspace: free to start, then $12 a seat a month for a small team on Plus. Pick Obsidian if you are the only reader. Pick Notion if your team is.

Prices below were read on 25 September 2026 from Notion's pricing page (USD, currency selector set to United States) and Obsidian's pricing page. Toolradar data: we track 184 note-taking apps as of September 2026, and on our own Notion vs Obsidian scorecard, Obsidian's 12 user reviews average 4.5 out of 5 against Notion's 407 reviews at 3.5, the widest satisfaction split of any head-to-head pairing we track in the category.

At a glance

Notion's per-seat prices above are what a workspace pays for every paid member; the lower figure in each pair is the annual-commitment rate, and the higher one is what you pay staying on the flexible monthly plan. Obsidian flips that logic: the note-taking app itself has no seat price at all, and only the two optional services, Sync and Publish, carry a subscription, each discounted about 20% for paying yearly instead of monthly.

What free actually gets you

Notion's free plan is generous for one person: unlimited pages and blocks, unlimited file uploads capped at 5 MB each, a trial of Notion AI, and access to Notion Calendar. The catch shows up the moment a second person joins a workspace: block limits kick in for 2+ member workspaces on the free tier, so a two-person team hits a ceiling that a solo user never sees. Guests are capped at 10, and page history only reaches back 7 days.

Obsidian's free plan has no such asterisk. There is no member limit, no block cap, no file-upload ceiling, and no sign-up required to start; you download the app and open a folder. The tradeoff is structural rather than financial: everything lives on your device by default, so getting the same vault on a second device means manually copying files, using a third-party sync tool, or paying for Obsidian Sync. Notion solves that automatically because it is cloud-first from the start; Obsidian makes you opt into the cloud, and charges for it, precisely because staying local is the point.

Cloud workspace vs local files

This is the real fork in the road, and it decides almost everything else on this page. Notion stores every workspace on its own servers. That is what lets shared pages, comments, and @-mentions work at every tier without any setup, and it is also why exporting a Notion workspace is not a folder copy: Notion's own help docs describe a full-page database exporting as a CSV file with separate Markdown files for each subpage, not as one portable file per note.

Obsidian stores every note as a plain Markdown file on your own disk. Nothing is locked in a proprietary format, so a decade-old vault opens in any text editor, and switching tools later is a folder copy, not a migration project. The cost is that collaboration is not native: Obsidian Sync adds shared vaults, encrypted end to end, with version history per note (1 month on the base Sync plan, 12 months on the higher tier), but it works more like a shared, synced folder than Notion's built-in shared pages and comments. If your work is mostly solo thinking, Obsidian's model removes a whole category of vendor risk. If your work is mostly shared documents, Notion's model removes a whole category of setup friction.

AI: a built-in agent vs a plugin ecosystem

Notion bundles its AI starting on the Business tier: Notion Agent, described on the vendor's pricing page as handling complex, multi-step tasks using context from your workspace, connected apps, and the web, plus AI Meeting Notes that write up calls automatically and an Enterprise Search feature still in beta that searches across connected tools like Slack and GitHub. Free and Plus only get a limited trial of that AI, not the full version, so a small team on Plus is paying for collaboration features without the AI its bigger sibling gets.

Obsidian ships with no built-in AI in the core app or in Sync and Publish. What it has instead is scale: Obsidian's own community plugin directory on GitHub lists over 8,000 published plugins as of today, several of which add AI chat, summarization, or auto-tagging on top of your local notes, using whichever AI provider and API key you choose to configure. That is more setup than Notion's flip-a-toggle approach, and it means AI quality varies by which plugin you pick, but it also means you are never locked into one vendor's model or its per-credit pricing, unlike Notion's separate Custom Agents feature, which is free to try and then billed per 1,000 monthly Notion credits.

Collaboration and team features

Notion's collaboration story is built in from the free plan up: shared pages, comments, and mentions all work without an add-on. Business adds SAML SSO, granular database permissions so a collaborator can be scoped to just their assigned rows, and private teamspaces that stay invisible to the rest of the workspace, useful for planning or performance reviews a whole company should not see.

Obsidian's version of team features lives entirely inside the Sync add-on: shared vaults with role-based access (owner or can-edit), end-to-end encryption so Obsidian itself cannot read your notes, and priority support once you are paying. It is a smaller feature set than Notion's, deliberately so, since the product's whole premise is that your notes are private by default. A team that wants a shared knowledge base with real permission tiers, not just shared folders, is choosing Notion's model whether it realizes it or not.

The 10-person team math

Run the numbers for a 10-person team and the gap is stark. Notion Business billed monthly costs that team $240 a month, or $200 a month on the annual rate, and that price includes Notion Agent and AI Meeting Notes for everyone. Obsidian has no per-seat workspace price to compare directly: 10 people who each want Sync pay $40 a month combined on the annual rate ($50 on the flexible monthly rate), about a fifth of Notion Business, with no seat-based AI or admin console layered on top, because Obsidian does not sell one.

That comparison only holds if the Obsidian team is fine coordinating over shared vaults instead of a managed workspace with roles and SSO. A regulated company that needs admin controls, audit logs, and single sign-on is really comparing Notion Business against Notion Enterprise, or against a completely different category of tool, not against Obsidian, which publishes no admin console at any price.

Customization: databases vs plugins

Notion's flexibility comes from its block-and-database model: any page can become a filterable, sortable database with custom properties, and non-technical teams build fairly complex trackers, wikis, and lightweight project boards without writing code. The limit is Notion's own roadmap; you get the primitives Notion ships and combine them, but you cannot extend the app itself.

Obsidian's flexibility comes from the opposite direction: a small, opinionated core (Markdown files, links, and a graph view) plus an open API that over 8,000 community plugins build on, covering everything from calendar-style daily notes to kanban boards to advanced database-style queries across your vault. Canvas, included free, adds an infinite whiteboard for research and diagramming on top of that. The tradeoff is real: a Notion database works the moment you create it, while an Obsidian plugin setup takes longer to configure and depends on volunteer maintainers rather than a vendor support contract.

Who should choose which

Choose Obsidian if you are the primary or only reader of your own notes, you want your archive to outlive any single company, and you do not want a subscription just to write. The core app costs nothing, ever, and Sync's small monthly fee is optional even for multi-device use if you are comfortable syncing through your own cloud storage folder instead.

Choose Notion if notes are really a team artifact: a wiki other people search, a project tracker several people update, or a database that stays current for everyone without a separate merge step. The free plan works fine solo, but budget for Plus or Business the moment a second teammate needs shared access, since that is where Notion's block limits and AI features actually kick in.

Run both, which is common among people who write for themselves in Obsidian and publish the finished version to a Notion-based team wiki; starting from Obsidian's free core app and Notion's own free tier, the combined cost stays low until a workspace genuinely needs Notion's paid AI or admin controls.

Where each app fits around the edges

Neither tool is a full productivity stack by itself. If note-taking is one piece of a bigger AI toolkit you are assembling, our best AI note-taking apps roundup covers tools built AI-first rather than AI-added, and our full Notion review goes deeper on the workspace side alone. Teams evaluating Notion as a company-wide system of record should also compare it against dedicated best knowledge base software and best project management software, since Notion competes with both categories at once rather than replacing either outright. Anyone using notes for research or brainstorming with a visual layer should see best digital whiteboards, which covers Canvas-style tools beyond Obsidian's built-in one. If your notes end up holding files as much as text, best cloud storage for business is worth a look before you build a storage habit around either app. For the broader AI layer sitting on top of whichever notes app you pick, see AI for productivity, how to use AI at work, and ChatGPT for productivity.

How we compared

We read Notion's pricing page and Obsidian's pricing page directly on 25 September 2026, with Notion's currency selector set to United States so every figure above is USD, not a converted estimate. Plugin counts come from Obsidian's own community-plugins directory on GitHub, pulled the same day. Feature claims come from each vendor's current pricing and product pages, not from memory or an earlier comparison. Nobody paid for placement or ranking on this page, and Louis Corneloup, founder of Toolradar and Dupple, edited the verdict. Re-check both vendors' current pricing before you commit, since either can change a tier's price or contents without much notice.

FAQ

Is Obsidian really free, or does it have a catch?

The core app is free with no feature gate, no trial period, and no sign-up requirement, verified on Obsidian's own pricing page today. The only paid pieces are two optional add-ons: Sync, for encrypted multi-device sync, at $4 to $5 a month, and Publish, for turning a vault into a public site, at $8 to $10 a month. You can use Obsidian daily, forever, without ever touching either.

Is Notion free for personal use?

Yes. Notion's Free plan covers unlimited pages and blocks for a single user, a trial of Notion AI, and Notion Calendar, at $0. The block limit that trips people up only applies once a workspace grows to two or more members, so a solo user on the free plan will not hit it.

Which is cheaper for a small team, Notion or Obsidian?

Obsidian, by a wide margin, if the team is fine without a shared managed workspace: Sync's per-person fee has no seat minimum or admin tier attached. Notion charges meaningfully more per seat on Plus for shared docs and databases, and jumping to Business for Notion's AI agent roughly doubles that again. The gap widens fast as headcount grows, since Notion prices per seat and Obsidian's team feature, Sync, does not bundle admin controls at any price.

Does Obsidian have built-in AI like Notion does?

No, not in the core app, Sync, or Publish. Notion bundles its own AI agent, meeting notes, and enterprise search starting on the Business plan. Obsidian relies on its community plugin ecosystem, over 8,000 plugins as of today per its own GitHub directory, some of which add AI features using whatever provider and API key you supply yourself.

Can I use Notion and Obsidian together?

Yes, and it is a common setup: write and think privately in Obsidian, then copy or publish the polished result into a shared Notion page for the team. Since both have a $0 tier, the combined cost is whatever Obsidian add-ons or Notion seats you actually need, not a forced bundle price.

Which app is better for a team wiki, Notion or Obsidian?

Notion, for most teams. Its shared pages, database-driven layout, and permission controls (granular on Business) are built for several people working in the same space day to day. Obsidian Publish can turn a vault into a public wiki, but it is closer to a documentation site than an editable team workspace, and Obsidian's own collaboration feature stops at shared, synced vaults with version history rather than a managed team space with roles and permissions.

Does either app lock in my data?

Obsidian does not: every note is a plain Markdown file on your disk, readable by any text editor even if Obsidian disappeared tomorrow. Notion stores your workspace on its own servers, and while it offers exports to Markdown, HTML, PDF, and CSV, Notion's own help docs describe a full-page database exporting as a CSV file plus a separate Markdown file per subpage, so a full migration out of Notion is more involved than a folder copy.
