Choose Obsidian for local, customizable, linked markdown notes. Choose Notion for a collaborative cloud workspace with databases. If you want something calmer than both for personal notes on Mac, atiea is a third option.
Obsidian and Notion are often compared, but they solve different problems. One is a personal knowledge base built on local files; the other is a collaborative workspace in the cloud. This page gives you the core difference, a side-by-side table, a way to decide, and a third option for Mac users. For wider context see the best markdown notes apps for Mac.
The core difference
Obsidian stores notes as markdown files in a folder (a vault) on your device and grows through plugins. It is a proprietary app that runs on several platforms. Notion stores pages and databases in the cloud, requires an account, and is built for sharing and teamwork. Most of the other differences follow from that one choice: files you own versus a service you use.
Comparison
| Aspect | Obsidian | Notion |
|---|---|---|
| Storage | Local markdown files | Cloud workspace |
| Account | Not required to use locally | Required |
| Linking | Wiki links and backlinks | Page links and mentions |
| Collaboration | Not its focus | A core strength |
| Databases | Via plugins | Built in |
| Customization | Extensive via plugins | Templates and blocks |
| Offline use | Natural, files are local | Depends on features and setup |
| Exit cost | Low, files are plain markdown | Higher, content lives in the service |
Both products change often, so check each product’s site for current details.
Choose Obsidian if
- You want to own your notes as plain files that any editor can open.
- You like building your own system and tuning it over time.
- Your notes are mostly personal, and linking ideas matters more than sharing them.
- You want to work offline without thinking about it.
Choose Notion if
- You work with a team and need shared documents.
- You need databases, boards and structured views in the same place as your writing.
- You want one workspace for notes, tasks and projects.
- You are comfortable with your content living in a cloud service.
Writing and markdown
Obsidian is markdown-native: what you type is what is stored, and the files are portable. Notion accepts many markdown shortcuts as you type and converts them to its own blocks, so the underlying content is not a markdown file. If you are new to the syntax, our markdown cheat sheet and what is an .md file explain the format you would be committing to.
Linking and structure
Obsidian popularized [[wiki links]] and backlinks for personal notes, where you connect ideas as you write. Notion links pages and builds structure through databases and hierarchy. Neither approach is better; one grows like a web, the other like a filing system with views. If linked notes appeal to you, read what wiki links and backlinks are and Zettelkasten for beginners.
Privacy and ownership
With local files, your notes sit on your own disk and you decide whether to sync them. With a cloud workspace, your content lives on the provider’s servers, which is what enables collaboration but also means you depend on the service. Which matters more is personal. Our piece on private, local-first notes apps lays out the trade-offs.
A decision framework
- Will other people edit your notes? If yes, Notion.
- Do you need databases or project boards? If yes, Notion.
- Do you want plain files and offline use? If yes, Obsidian or another local markdown app.
- Do you enjoy configuring tools? If yes, Obsidian. If no, consider something simpler.
- Is it mostly just you, on a Mac? Then both may be more than you need.
Common mistakes
- Using one tool for everything. It is fine to use a collaborative workspace for team projects and a local notebook for personal thinking.
- Building elaborate systems first. Both tools tempt you to design templates before you have notes. Write first, organize later.
- Ignoring exit cost. Ask how you would get your content out before you store years of it.
- Comparing features instead of habits. Pick the one you will actually open every day.
A third option
If you want local, markdown-based notes without the setup, try atiea, a native Mac app (macOS 15 or later). It has live syntax highlighting, wiki links with backlinks, inline tags and pinned notes. Notes stay on your Mac, and no account is required. It exports to Markdown, HTML, PDF and DOCX. See atiea vs Obsidian and atiea vs Notion, or browse more options in Obsidian alternatives.
When not to use atiea
atiea is a personal tool for Mac. If you need real-time collaboration, shared databases, plugins or apps on non-Apple platforms, Notion or Obsidian is the better fit. Treat it as the calm option for solo writing, not a replacement for a team workspace.
Using both
Plenty of people split the work: Notion for shared projects, a local markdown notebook for private notes and drafts. If you take that route, keep personal notes in plain markdown so you can export or move them later, and see how to take notes in markdown for a simple starting habit.
Who should choose what
| If you are | Lean toward | Why |
|---|---|---|
| A student keeping lecture notes | Obsidian or a local markdown app | Linked notes and plain files last beyond a single course |
| A small team planning projects | Notion | Shared pages, databases and permissions are built in |
| A writer drafting long pieces | A markdown app | Distraction-free text that exports cleanly |
| A researcher building a knowledge base | Obsidian | Backlinks and a plugin ecosystem suit large linked collections |
| Someone who wants one tidy personal notebook on Mac | A native app such as atiea | Less to configure, notes stay local |
These are tendencies, not rules. Many people succeed with the “wrong” tool because they use it consistently, and consistency matters more than the label on the app.
Moving between them
Switching in either direction takes planning, because the two tools store content differently. Moving from Obsidian to Notion means taking markdown files into a block-based system, so test a few notes and check that tables, checklists and links survive. Moving from Notion to a markdown notebook means exporting pages and then cleaning up anything that relied on databases or embedded blocks, which do not have a plain-text equivalent. In both cases, work from copies, migrate a small batch first, and keep the original until you have lived with the new setup for a few weeks. Import options differ by product and change over time, so check each product’s documentation for the current process.
The lesson is to treat your notes as an asset you may need to move. Plain markdown, standard headings, simple tables and task lists travel well; heavy reliance on app-specific features does not.
