A cloud workspace for teams vs a local vault you own outright.
| Notion | Obsidian | |
|---|---|---|
| Data storage | Notion's cloud, exportable | Local markdown files you own, syncable if you choose |
| Core price | Free tier; Plus $10/member/mo (annual) | Free, including commercial use |
| File format | Proprietary blocks, exports to markdown/CSV/PDF | Plain markdown, no export needed |
| Offline use | Partial and historically unreliable | Fully offline by design |
| Collaboration | Real-time editing, comments, permissions, guests | Minimal; built for one person |
| Databases | Core strength: relational tables, views, formulas | Approximated via plugins (Dataview, Bases), not the focus |
| Linking and graph | Backlinks supported, secondary feature | Core strength: wiki links, backlinks, graph view |
| Extensibility | Integrations, API, templates | Thousands of community plugins, full theming, open plugin API |
| AI | AI included in Business plan, agents and Ask Notion | None built in; community plugins connect your own AI tools |
| Best for | Team wikis, project tracking, structured docs | Personal knowledge management, research, long-lived notes |
These are the published prices as of August 2026. Notion bills per member; Obsidian's app is free and its optional services are add-ons.
| Tier | Notion | Obsidian |
|---|---|---|
| Free | $0, generous for individuals, limited blocks for teams | $0, full app, all features, commercial use included |
| First paid tier | Plus: $10/member/mo billed annually (about $12 monthly) | Sync add-on: from $4/mo billed annually |
| Higher tier | Business: $20/member/mo billed annually, includes Notion AI | Publish add-on: $8/site/mo billed annually |
| Enterprise | Custom pricing | Not applicable |
Note the shape of the difference. A five-person team on Notion Business is $100 a month. A solo Obsidian user who syncs through iCloud or their own git repo pays exactly nothing, forever. Obsidian also dropped its old commercial-license requirement, so business use of the free app is now officially free.
Pick Notion when more than one person needs to touch the notes. Shared project trackers, a team wiki, client-facing docs, meeting notes with comments and mentions: this is what Notion is actually for, and nothing in Obsidian's world does it well. The databases are the killer feature. A single table of clients or projects can become a kanban board, a calendar, and a filtered list without duplicating data, which quietly replaces a lot of spreadsheet work.
It is also the better pick if you want structure handed to you. Templates for CRMs, content calendars, and OKRs are a click away, and the Business plan's AI can search and summarize across your whole workspace. For a small business that needs one shared brain with low setup effort, Notion is the pragmatic default, and the free tier is enough to find out if it sticks.
The tradeoff is dependence. Your data lives in Notion's cloud, offline access is weak, and exports flatten the database structure you built. You are renting the system, not owning it.
Pick Obsidian when the notes are for you and you intend to keep them for decades. Because everything is a plain markdown file in a folder you control, your vault works without internet, opens instantly even at tens of thousands of notes, and will still be readable in twenty years by any text editor. No subscription lapse or company pivot can take your notes away. For research, journaling, and building a personal knowledge base, that permanence changes how much you are willing to invest in the system.
The linking model rewards thinkers. Wiki-style links, backlinks, and the graph view make connections between ideas visible in a way Notion's page tree never quite does. The plugin ecosystem, thousands of community plugins, means the app becomes whatever you need: spaced repetition, task management, canvas boards, or a front end for your own AI tools. Local files also play unusually well with coding agents, which is a bigger deal in 2026 than it sounds.
The tradeoff is that you assemble it yourself. Out of the box Obsidian is a blank folder, sync across devices costs $4 a month or some DIY setup, and real-time collaboration essentially does not exist.
Most comparisons frame this as a feature checklist when it is really a question about time horizons. Notion optimizes for this quarter: fast setup, shared visibility, structure on demand. Obsidian optimizes for the next twenty years: a pile of plain text that no vendor can hold hostage. Neither optimization is wrong, but people pick Notion for personal notes and then feel a vague unease they cannot name. The unease is that their thinking now has a landlord.
The other miss is assuming you must choose. The pairing that actually works, and the one I see most among people who take notes seriously, is both: Notion (or something like it) as the shared operational layer for the team, Obsidian as the private thinking layer for yourself. They solve different problems, both have honest free tiers, and the overlap between them is smaller than the marketing on either side suggests.
For a team, pick Notion and do not overthink it; the collaboration and databases are worth $10 to $20 a member and nothing else in this category matches them. For a personal knowledge base you want to still trust in ten years, pick Obsidian; free, local, and permanent beats polished and rented for notes that matter to you. If you are one person choosing for yourself and unsure, start with Obsidian, because plain files keep every future option open while Notion habits are harder to walk back. And running both, team layer plus personal vault, is not indecision. It is the setup that fits how most work actually splits.
