Notion vs Obsidian: Cloud workspace or a folder (2026)

This is the first question and most people skip it. A Notion page is a tree of blocks in Notion's database, reachable through Notion's app or Notion's website. Nothing on your machine corresponds to a page you wrote. The export formats are HTML, Markdown, CSV, and PDF, and Notion's own help pages warn that a large workspace can take up to 30 hours to get out.

An Obsidian note is a file. It has a name you chose, an .md extension, and a path in Finder. Pandoc can convert it, ripgrep can search it, a Python script can rewrite four hundred of them while Obsidian is closed. Uninstall Obsidian and the folder is untouched, which is the reason a lot of people picked it and has nothing to do with any feature.

The asymmetry compounds. A Notion workspace becomes more expensive to leave every month you add to it, because every page is one more block tree to convert. A markdown folder costs exactly the same to leave in year eight as in week one, which is zero.

Notion's databases are the reason it is the default answer in most offices. One dataset appears as a table, a kanban board, a calendar, or a gallery, each with its own filters and sort order. A relation makes one row hold another, a rollup counts across the set, and a template button creates next week's meeting note already structured. Nothing in the markdown world matches this, and pretending otherwise wastes your time.

Obsidian's answer is Dataview, a community plugin that queries the frontmatter of your notes and renders tables from it. It is genuinely powerful and it is also a query language you learn, maintained by a volunteer, rendering results that live nowhere except inside Obsidian. Notion's databases are the product. Obsidian's are an add-on with a bus factor.

Obsidian does have wikilinks and backlinks, and Notion has both as well. What Notion has no version of is the graph view, and what Obsidian has no version of is a filtered relational table your colleague can edit in a browser.

Notion's own documentation is clear about this: offline covers pages you recently opened or explicitly marked for offline use, and the browser version has no offline mode at all. So a flight, a dead hotspot, or a Notion outage decides which of your notes exist for the next few hours. Notion records offline support as partial itself, so this is the vendor's own framing rather than a critic's.

Obsidian reads from the disk. Every note is available with the wifi switched off because the wifi was never involved in opening a file. Search runs locally, the graph builds locally, and the only thing that needs a network is whichever sync method you chose. This gap is small on a good day and total on a bad one.

Obsidian's community has published more than 2,000 plugins, and that number is the moat. Excalidraw draws inside a note, Templater scripts new files, Kanban turns a list into a board, and a theme gallery lets you make the app look like anything. If you enjoy building your own system, this is the most fun software in the category.

The bill for that arrives in maintenance and in startup time. Obsidian's forum carries threads about slow launches on large vaults with many plugins loaded, plugin quality varies, and mobile compatibility is a documented sore point. Notion has no plugin problem because Notion has no plugins. What ships is what you get, it works the same on every machine you log into, and nothing breaks at 11pm because a volunteer stopped maintaining a repository.

Which one wins depends entirely on whether configuring software is a pleasure or a tax for you. There is no objective answer and anyone who gives you one is selling something.

Notion has put AI at the centre of the product. There are agents, meeting notes, and enterprise search, and after the standalone AI add-on was retired in May 2025 those capabilities sit on the Business tier at $20-24 per user per month. Whether that pricing move was fair is a separate argument from whether the features work.

Collaboration is the harder gap. Notion has permissions, member roles, comment threads, and two cursors in one paragraph. Obsidian has a folder, which you can share through a git repository or a synced drive, and no concept of another person being in the note with you. Teams that tried to run a shared Obsidian vault usually end up with a merge problem instead of a workflow.

Obsidian has no built-in AI either. Community plugins wire up OpenAI or a local model, with the usual caveat that you are trusting a volunteer's code with your API key.

Obsidian has been free for personal and commercial use since February 2025, with an optional $50 per user per year commercial licence you can buy to support the project. The only recurring cost is Obsidian Sync at $4-5 a month, or $8-10 a month for Publish if you want notes on the web. Sync all by yourself with iCloud or Syncthing and Obsidian is a genuinely free app.

Notion is free for one person, and the free tier is unusually generous. Add a second person, or want AI, and you are at $10-12 or $20-24 per user per month. Five years of Plus for a three-person team is somewhere near $2,000. Five years of Obsidian with Sync is around $270 for one person, or nothing if you sync it yourself.

There is a real caveat on Obsidian's free sync routes. The community git plugin has documented index.lock errors, line-ending conflicts, and merge handling on mobile that its users describe as unstable. Free is not the same as painless.

Notion is free for a solo user and that free tier is the strongest in the category, so the honest comparison for one person is free against free. Obsidian is free too, including commercial use since February 2025, with the $50 per user per year commercial licence optional. Costs appear from different directions. Notion's arrives when you add people, at $10-12 per user per month on Plus and $20-24 on Business where the AI now lives. Obsidian's arrives if you want its own sync, at $4-5 a month, or in unpaid time if you wire up iCloud, Syncthing, or the git plugin instead. Valutorio charges for the app on the Mac App Store and again, optionally, for sync; what its sync line buys that Obsidian's does not is conflict handling that never surfaces a marker, and a personal MCP endpoint for an AI assistant.
