Notion vs Obsidian for solo consultants
For a one-person practice this is not really a features question. Both tools will hold your notes. What separates them is where client material physically sits, what you still have if you stop paying, and one licensing question that half the internet answers wrongly.
All figures verified 4 August 2026 against vendor pricing pages and independent trackers.
Start with the licence, because the internet has this wrong
Search for Obsidian pricing and you will find pages stating plainly that a $50 per user per year commercial licence is legally required for business use and written into the EULA. You will also find more recent pages saying the requirement was removed and any business may use Obsidian for work at no cost.
Both cannot be true, and for a consultant it is not academic — it is the difference between a free tool and one with an annual fee attached before you have opened it.
What we found, and what we concluded
Four independent sources published between April and August 2026 describe the licence as optional or voluntary, and one of them names a specific date for the change. Two others, one undated and one from April 2026, describe it as required. The more recent and more numerous reading is that it is optional.
The sources also disagree about when it changed — February 2025 in one, February 2026 in another — which suggests at least one is repeating the other carelessly.
We have followed the optional reading. It is the only figure on this page we would not act on without checking Obsidian’s own terms first, and if you are budgeting for a client engagement, do that.
Five years, one seat
With the licence set aside, the cost comparison is lopsided. Obsidian’s app is free and its only routine cost is Sync at $48 a year, which you can also avoid entirely by keeping the vault in iCloud, Dropbox or a private Git repository. Notion Plus is $120 a year and Business $240.
A $600 spread over five years is real money for a solo practice. It is also not the reason to choose either one, and any comparison that stops here has told you the least interesting thing about the decision.
Where the work actually lives
This is the structural difference and, for client work, the one that matters. An Obsidian vault is a folder of Markdown files on your own disk. Notion is a hosted database you reach over the network. Everything else follows from that.
Ask the same question of each: what do you still have the day you stop paying? With Obsidian, a folder that opens in any text editor — including one that will still open in ten years. With Notion, a workspace that drops to the free tier and content you can export, with some formatting loss and any database relations flattened.
For a consultant that has a second edge to it. If client material never leaves your machine by default, the conversation about where their data is stored gets shorter. That is a default, not a guarantee — disk encryption, backups and reviewing what your plugins do are all still your problem.
Where each one is genuinely better
A consultant does several different jobs in one tool, and the answer changes per job. The split is close to even.
The pattern is consistent: Obsidian is better where the work is yours and private, Notion where the work is shared. Thinking, research and confidential notes on one side; client-facing pages, structured records and handover on the other.
So which one
Obsidian if your practice is research-heavy, your clients care where their material sits, or you want a system that outlives whatever you are paying for this year. Budget $0 to $48 a year and about five hours of setup, because it is not plug-and-play.
Notion if you regularly hand things to clients — proposals, dashboards, project spaces — or if structured records with views and relations are central to how you work. Budget $120 a year and considerably less setup.
Both is the common answer among consultants who have used each for a while: think in Obsidian, deliver in Notion. That is $168 a year, less than Notion Business alone, and it puts each tool where it is strongest.
Common questions
Do I need to buy Obsidian’s commercial licence as a consultant?
Almost certainly not, but the internet disagrees with itself on this. Several pricing sites still state that the $50 per user per year commercial licence is legally required for business use and written into the EULA. More recent sources, including one naming a specific date, say the requirement was removed and any business may now use Obsidian for work at no cost. The recent reading is better supported, so we follow it — but the licence is the one figure on this page we would check against Obsidian’s own terms before relying on.
Which is cheaper for one person?
Obsidian, substantially. The core app is free and Sync is an optional $48 a year, against $120 a year for Notion Plus and $240 for Business. Over five years that is $240 versus $600 or $1,200. You can also skip Sync entirely and keep the vault in iCloud, Dropbox or a private Git repository.
What happens to my client notes if I stop paying?
This is the real difference. An Obsidian vault is a folder of Markdown files on your own disk — stop paying for Sync, or stop using Obsidian altogether, and the folder still opens in any text editor. A Notion workspace lives on Notion’s servers; the free tier keeps working, but moving the content elsewhere means running an export and accepting some formatting loss.
Can I share work with clients from Obsidian?
Not as easily. Notion shares a page with a link and no publishing step, which is why consultants who need client-facing deliverables tend to keep Notion for that even when they think in Obsidian. Obsidian Publish turns selected notes into a website for $96 a year, but it is a published site rather than a shared document.
Is Obsidian better for confidential client work?
By default, yes, in the narrow sense that notes never leave your machine unless you turn on sync or a plugin that phones out. That is a meaningful default for regulated or NDA-bound work. It is not a security guarantee — disk encryption, backups and plugin review are still yours to manage, and Obsidian Sync is end-to-end encrypted if you use it.
How we checked this
Prices and terms were taken from vendor pricing pages and cross-checked against six independent trackers on 4 August 2026. Where they disagreed — the commercial licence, and whether Obsidian Sync is still split into two tiers — we have said so rather than picked the tidier answer. We have not run either product for this guide; it is desk research, and thorough, and those are different things. Our full method is on the about page.
