Ask a group of students where they keep their notes and two names come up again and again: Notion and Obsidian. They look similar at first glance, but they are built on very different ideas. Obsidian is a fast, private notebook made of plain text files that you link together. Notion is an all-in-one workspace where notes, databases, calendars and to-dos live side by side. Here is the honest comparison, so you can pick the one that fits how you actually study.
The 30-second answer
- Choose Obsidian if you mostly write and connect a lot of notes, want everything offline and stored as plain Markdown files you own, and enjoy tweaking your setup with plugins.
- Choose Notion if you want your notes, deadlines, weekly plan and flashcards in one visual workspace, easy to share with classmates, and you would rather start from a ready template than build a system yourself.
Side by side
| What matters | Obsidian | Notion |
|---|---|---|
| Where notes live | Markdown files in a folder on your device | In the cloud, in your Notion workspace |
| Offline | Offline by default | Offline mode for downloaded pages (since 2025) |
| Linking notes | Excellent: backlinks, graph view | Good: page links, mentions, relations |
| Planning & tasks | Possible with plugins | Built in: databases, calendar, board and timeline views |
| Flashcards & review | Community plugins | Template-driven (e.g. Flashcards Pro) |
| Group projects | Shared vaults via paid Sync, not live co-editing | Real-time sharing and comments |
| Learning curve | Simple to start, deep to customise | Gentle with a ready template |
| Cost | Free app; Sync from $4/month | Free plan for personal use |
Where Obsidian wins
Your notes are just files. Every note is a Markdown file in a folder on your computer. Nothing is locked into an app, it opens instantly, and it works on a plane or in a library with bad Wi-Fi. If Obsidian disappeared tomorrow, your notes would still be readable in any text editor.
Linked thinking. Obsidian is brilliant at connecting ideas. Type [[, link to another note, and the backlinks panel and graph view show how a concept connects to everything else you've written. For subjects where ideas build on each other, such as medicine, law, philosophy or a thesis, this is a real advantage.
Free and private. The app is free, including for work, and your notes stay on your device unless you choose to sync them. Official Sync costs from $4 a month billed annually, with 40% off for students, or you can sync the folder yourself with a cloud drive.
Where Notion wins
One place for your whole study life. Notion is not just a notebook. Class notes, assignment deadlines, a weekly plan, reading lists and flashcards can all live in one workspace, connected through databases. You can view the same assignments as a list, a calendar or a board by due date, which Obsidian can only approximate with plugins.
Visual and easy to share. Pages look clean out of the box, and sharing a page with a study group or a project partner takes one click. Everyone can edit and comment at the same time, which matters for group work.
Templates do the setup for you. Instead of building a system from scratch, you can duplicate a ready-made one and start studying the same day. That is a big reason students who bounce off Obsidian often stick with Notion.
The trade-offs are real, though. Notion lives in the cloud, so very large pages can feel slower than Obsidian, and offline use depends on downloading pages first. Since August 2025 the desktop and mobile apps can save pages for offline use, and paid plans download your recent and favourite pages automatically.
Flashcards and spaced repetition in each
Neither app has spaced repetition built in, so this is where your choice of add-on matters most.
In Obsidian
The popular Spaced Repetition community plugin turns lines in your notes into flashcards. You write a question and answer separated by ::, or hide key words as cloze deletions, tag the note with a deck, and the plugin schedules reviews using an algorithm based on Anki's SM-2. It is clever because your cards stay inside your notes, but it is plain text: there is no visual dashboard, and it takes a little setup to get right.
In Notion
Plain Notion has no review scheduler, so you need a system built for it. That is what Flashcards Pro adds: a flashcard database with review scheduling, a spaced-repetition scheduler, a quiz mode that tests you instead of letting you re-read, matching games and a progress dashboard. Your cards sit right next to your notes and your study plan.

- You write long, dense notes and want to connect ideas (medicine, law, research, a thesis): Obsidian.
- You need to work offline a lot or care about owning your files: Obsidian.
- You juggle classes, deadlines and group projects: Notion.
- You want notes, a weekly plan and flashcards in one place without building it yourself: Notion with a template.
- You can't decide: start with the one you'll open every day. The best study system is the one you actually use.
Can you use both?
Yes, and plenty of students do. A common split is Obsidian for long-form notes and personal knowledge, and Notion for everything that has a date or a status: assignments, exam prep, a weekly planner and flashcard reviews. The only rule is to decide which app is the home for each kind of information, so you never wonder where something lives.
Bottom line
Obsidian is the best pure notebook: fast, offline, private and brilliant at linking ideas, at the cost of more setup and fewer built-in planning tools. Notion is the better home base for a busy student: notes, deadlines, planning and, with a template like Flashcards Pro, spaced-repetition flashcards in one calm workspace. If your notes already live in Notion, you don't need to switch. Add the study system that Notion is missing.

Frequently asked questions
Is Notion or Obsidian better for students?

Is Obsidian free?
Yes. The Obsidian app is free, including for work. You only pay for optional add-ons: Sync starts at $4 per month billed annually and Publish at $8 per month billed annually, and students get 40% off both.
Can Notion work offline like Obsidian?
Partly. Since August 2025 the Notion desktop and mobile apps can download pages for offline use, and paid plans download your recent and favourite pages automatically. Obsidian is offline by default because your notes are files on your own device.
Does Obsidian or Notion have flashcards and spaced repetition?
Neither has it built in. Obsidian relies on community plugins such as Spaced Repetition, which turns lines in your notes into cards. In Notion you use a template such as Flashcards Pro, which adds spaced-repetition scheduling, quiz mode and progress tracking.
