Notion vs Obsidian: shared company brain, or local second brain?

Short answer: open Notion when the artefact is a shared company brain — client wikis, teamspaces, databases, permissions, and pages other people must find without asking you where the file lives. Open Obsidian when the artefact is a local second brain — Markdown you own, offline by default, a graph you can reshape with plugins, and thinking that should not depend on a cloud workspace loading. Most studios do not need to migrate everything. They need a named job for each, and a handoff rule so personal vaults do not become shadow company docs.

This is a knowledge-system decision, not a feature laundry list. AI add-ons, database views, and plugin ecosystems move. The decision that lasts is whether Monday’s bottleneck is collaboration and shared structure, or ownership, privacy, and a vault that still works on a plane.

Both are on Unloc: Notion and Obsidian. If the fork is docs versus issue tracking, that is a different job — read Notion vs Linear. For calmer personal docs when the vault feels heavy, Craft is nearby. Browse more under Productivity on /tools.

Quick verdict

If you only have budget for one system this quarter, buy the one that matches the bottleneck. If the bottleneck is “where is the client page?”, Notion earns the seat. If the bottleneck is “I cannot think in a shared wiki”, Obsidian earns the vault — and you still need a place the team can find finished work.

What Notion is

Notion is a cloud workspace: docs, databases, teamspaces, forms, sites, and permissions aimed at running shared work in one place. Pages nest. Databases become roadmaps, content calendars, CRM-lite tables, and client wikis. Guests can be invited to a page without owning the whole workspace. For studios, that is the company brain job — the thing you send a new hire on day one.

Public Notion pricing currently spans Free, Plus, Business, and Enterprise. Notion’s live pricing story positions full Notion AI / Notion Agent capabilities on Business and Enterprise for new buyers, with Free and Plus describing a limited AI trial rather than the full agent suite — confirm the current matrix on buy week, because AI packaging has shifted. Connections, SSO, private teamspaces, and admin controls thicken as you climb plans. Names and AI credit mechanics move. The job does not: a shared page other people can find.

Notion is not local-first. Offline is partial (recents / favorites behaviour on supported clients — check current docs). It is not a personal Markdown folder you can zip and leave. If ownership and offline are the product requirements, you are in Obsidian’s lane.

What Obsidian is

Obsidian is a local-first Markdown app: your notes live as files in a vault on your device. Wikilinks, graph view, daily notes, and a large plugin ecosystem turn that folder into a personal knowledge system. Bases (core structured views over note properties) narrowed the old “Notion has databases, Obsidian does not” gap for personal organisation — without making Obsidian a realtime company wiki. You still own the files. You can open them in any editor. Sync and publish are optional products, not the core requirement to start.

Public Obsidian pricing is unusual on purpose: the app is free without limits for the core product — no sign-up required to take notes. Optional paid add-ons are Sync and Publish. Optional support licenses include Catalyst (one-time, early access) and a Commercial license that Obsidian encourages for organisational work but does not require for commercial use under their public FAQ — read the live pricing FAQ before you set policy. End-to-end encrypted Sync, version history, and shared vaults sit on Sync. Publish turns notes into a public site.

Obsidian is not your company permissions system. Plugins can approximate collaboration; they do not replace Notion’s teamspaces and guest model for a ten-person studio wiki. Use Obsidian when the thinking should stay yours until you deliberately publish or paste a finished note into the shared brain.

Side-by-side

Anything that would be wrong when next month’s AI packaging ships does not belong as a sticky claim. Check the product the week you buy.

Pricing snapshot

Both can start free. The numbers move, and the surprise is usually AI gating, Sync seats, or Business features — not the first empty page. We are not printing sticky monthly prices here. Read the live pages on buy week:

• Notion pricing — Free, Plus, Business, Enterprise (confirm Notion AI / Agent availability for new buyers on Free / Plus vs Business)
• Obsidian pricing — free core app; optional Sync, Publish, Catalyst, Commercial license

How to think about cost without inventing a spreadsheet:

• Notion Free is enough to evaluate solo. Multi-member Free has block limits — Plus is the usual small-team floor for collaboration without pretending AI is included the way Business markets it.
• If the studio’s reason to buy Notion is AI agents inside the workspace, budget from Business (or Enterprise) on current packaging — do not promise Plus buyers a full Agent suite without checking the live matrix.
• Obsidian’s core vault is free. Sync is what you pay for when phones and laptops must stay aligned with encryption. Publish is for a public garden, not for internal wikis.
• Obsidian’s Commercial license is encouraged for organisational use and helps fund the product; their public FAQ says it is not required. Set studio policy intentionally — do not invent a legal requirement that is not on the page.
• Two systems can be rational: Notion for the company brain, Obsidian for private research. Two systems is chaos when the same meeting notes live in both with no handoff rule.

Who Notion is best for

Notion is for studios that need a shared brain. Client wikis with guest access. Content calendars that producers actually update. Onboarding pages. Meeting notes that are not trapped in one person’s Downloads folder. It is also the honest pick when Obsidian already exists on three laptops and nobody can find the latest SOW.

Put the repeated shared jobs in a short internal rule: Notion for anything another human must find next week, Obsidian for private thinking until it is ready to graduate. That rule beats a migration project because a blog preferred Markdown purity.

Not ideal if

• You needed local-first ownership, true offline defaults, and plain Markdown files as the product. Use Obsidian.
• You assumed Free / Plus includes the full Notion AI Agent suite for new buyers. Check Notion pricing the week you buy.
• You wanted an issue tracker as the primary job. That fork is Notion vs Linear, not this page.
• You are about to dump unreleased client financials into a Free workspace with loose guest invites. Stop. Tighten permissions or do not paste it.

Who Obsidian is best for

Obsidian is for operators and creatives who need a second brain that remains theirs. Researchers synthesising sources. Writers collecting sparks. Founders thinking in private before a Notion page becomes politics. People who have been burned by a SaaS export and want files they can zip. Bases helps when personal structure needs table / card views without moving the vault into a cloud database product.

It is also the honest pick when Notion already exists as the company wiki and people keep pasting half-finished thoughts into shared pages that confuse the team. Keep the vault private. Graduate finished notes.

Not ideal if

• The studio needs realtime collaboration, guest clients, and role-based teamspaces as the daily product. Notion wins that job.
• You refuse to maintain plugins or a folder structure. Local freedom includes local responsibility.
• You needed SSO, audit logs, and enterprise DLP as the centre of the buy. That is Notion Enterprise (or another workspace suite), not Sync alone.
• You assumed Bases made Obsidian a drop-in Notion team database. Bases is powerful for personal structured views; it is not Notion’s multiplayer permissions model.

Studio workflows that hold up

The client wiki

Build it in Notion. One teamspace per client or a clear database of client pages. Permissions that match the contract. Guests for the client’s three readers — not the whole internet. Link finished artefacts; do not paste every Slack argument into the wiki. Obsidian can hold your private prep notes; paste only the graduated summary.

The personal research vault

Keep it in Obsidian. Daily notes, source clippings as Markdown, Bases views for status (reading / used / archived). Sync if you need phone capture. Do not make the vault the company of record. When a research pack is ready for the team, publish a clean page in Notion with sources attached.

The content calendar

Notion database with status, owner, channel, and due date. Views for this week and this month. AI autofill only on Business+ paths you have actually paid for — and still have a human accept the slug and the claim. Obsidian can draft posts offline; the calendar of record stays shared.

Handoff between personal notes and team page

Write the messy version in Obsidian. Edit once for voice. Create or update the Notion page with the clean version and a “last graduated” date. Delete or archive the temptation to edit both forever. Dual systems fail when both stay half true.

What you must not paste

Treat cloud workspaces and synced vaults as systems with access policies. Client credentials, unreleased financials, and secrets do not belong in a Free Notion page with twenty guests, or in a Publish site you forgot was public. Obsidian Sync is end-to-end encrypted per their public claims — still do not put passwords in notes. Read current security pages before you paste. A local file is not safer if it is also in an unencrypted backup someone else can read.

Running both without double-systems chaos

Notion = company brain. Obsidian = private second brain. One weekly ritual: graduate or delete. Cancel Sync if you only work on one device. Downgrade Notion if the wiki is a graveyard. Review AI seats quarterly — if nobody opens Agent, stop paying for the story of Agent.

Calmer docs without the vault weight: try Craft for personal writing if Obsidian’s plugin surface is the problem and Notion’s databases are overkill. Do not add Craft as a third company brain.

Onboarding week without a second wiki

New hires get Notion: handbook, client list, how we name pages. They may keep Obsidian for private learning notes. Do not ask them to recreate the company graph in a personal vault. Do not ask them to paste diary entries into the shared wiki. Write the split in the handbook once. Revisit it when someone starts maintaining a shadow Notion of their own.

Questions people actually search

Is Obsidian better than Notion for personal knowledge management?

For local-first PKM with Markdown ownership and offline defaults, yes — that is Obsidian’s centre of gravity. For a personal system that must also be a shared team wiki, Notion is usually better. Better means better at the artefact, not a permanent app ranking.

Can Obsidian replace Notion for a small team?

Only if the team accepts local / Sync collaboration limits and someone owns structure. For guest clients, permissions, and a handbook everyone can find, Notion remains the safer company brain. Many five-person studios run Notion shared and Obsidian private rather than forcing a full replace.

Does Notion work offline like Obsidian?

Not in the same way. Notion offers partial offline behaviour for recent and favorite content on supported clients; Obsidian’s default is local files. If offline is a hard requirement, test Notion’s current offline behaviour on your devices before you promise a flight workflow — or use Obsidian for that work.

Notion vs Obsidian pricing for a five-person studio

Start from seats and jobs. Read Notion pricing and Obsidian pricing the same week. Notion’s bill scales with members and plan features (especially if AI is the reason to buy Business). Obsidian can stay near-zero until you add Sync seats or Publish. We do not print sticky dollar amounts here because they go stale.

Which is better for privacy and data ownership?

Obsidian for local ownership of Markdown files and optional end-to-end encrypted Sync. Notion for admin-controlled cloud workspaces with Enterprise security features when you need them. Consumer convenience is not a security review. Pick the threat model, then the tool.

Does Obsidian have real-time collaboration in 2026?

Obsidian Sync supports collaboration on shared vaults; it is not Notion’s realtime multiplayer wiki product. If simultaneous editing with guests and teamspace permissions is the job, Notion wins. If occasional shared vaults among trusted peers is enough, Sync can work — test it on a real project before you migrate the company handbook.

Notion AI vs Obsidian AI plugins — what’s the difference?

Notion AI / Agent is a vendor suite inside the workspace, currently marketed fully on Business and Enterprise for new buyers (verify live). Obsidian AI is mostly community plugins and external assistants pointed at your local files. Different trust boundaries, different admin stories. Neither is a substitute for reading the source note.

Should I migrate from Notion to Obsidian?

Migrate personal thinking if ownership and offline are the real pain. Do not migrate the company wiki because a blog preferred Markdown. Export carefully, expect reformatting, and keep Notion for anything clients or new hires must find. A half migration is worse than an honest split.

How to decide this week

Take two real pieces of work. One is a page another person must find next Monday without Slacking you. One is a private research note you would not put in a shared wiki yet. Put the first in Notion. Put the second in Obsidian. If the company will only fund one system, weight the shared findability problem more than personal taste — then give individuals permission to keep a private vault without making it shadow process.

Pay for the system that matches Monday’s bottleneck. If the bottleneck is shared structure, Notion. If the bottleneck is ownership and thinking space, Obsidian. Cancel the Sync or AI seat you stopped opening. Do not buy a third notes app until Craft or Linear has earned a named job on its own terms.
