Notion vs Obsidian: which is better for students?
Pick Notion if you want one place to plan the semester: class pages, an assignment database, a calendar and group projects, with Plus free on a school email. Pick Obsidian if you want fast, offline notes in plain files you own, linked into a web of ideas. Neither one tests you. To turn exported notes into flashcards and quizzes, StudyPDF is a third option.
They solve different problems. Notion is a cloud workspace made of pages and databases. Students use it as a semester dashboard: one page per class, a database of assignments with due dates, a calendar view, and shared pages for group work. Obsidian is a notes app that stores everything as Markdown files in a folder on your device. You link notes with [[double brackets]], and the graph view shows how lecture topics connect.
For students the price question is easy, as of October 2026. Notion's Plus plan is free for students and educators who sign up with a school email, for one member. Otherwise Plus costs $10 a month billed yearly. Obsidian is free for personal use, without an account. Its optional Sync costs $4 a month billed yearly, and students get 40% off, so about $2.40.
What neither app does is check whether you remember anything. Notes help you understand a lecture, but exams test recall. In Notion you can fake flashcards with toggle blocks, and Obsidian has community plugins for spaced repetition, but you still write every card yourself. That is the gap a study tool fills: export a page from either app and let it build the practice.

Tool by tool
Notion
Best for: Organizing classes, deadlines and group projects in one workspace
Notion is an all-in-one workspace of pages, databases and templates. It syncs through the cloud, so classmates can edit the same page, and Notion AI can summarize or draft inside your notes.
Strengths
- Databases with calendar, board and table views for assignments and exams
- Real-time editing on shared pages, good for group projects
- A large template gallery, including student dashboards
- Plus is free for students and educators with a school email
Limits
- Cloud-first, so it gets slow on weak connections and offline use is limited
- Easy to spend more time building the system than studying
- The Free plan caps uploads at 5 MB per file and page history at 7 days
Obsidian
Best for: Fast, private notes you own, linked into a web of ideas
Obsidian is a notes app that saves every note as a plain Markdown file on your device. You link notes to each other, see those links in a graph, and add features with community plugins.
Strengths
- Works offline and stays fast even with thousands of notes
- Notes are plain files, so any text editor can open them
- Backlinks and the graph view show how topics connect across a course
- Community plugins, including flashcards and spaced repetition
Limits
- Sharing and real-time group editing are limited
- Syncing between devices costs money unless you set up your own
- Takes setup: plugins, folders and habits are up to you
StudyPDF
That's usBest for: Turning exported notes and lecture slides into flashcards and quizzes

Strengths
- Reads notes exported from Notion or Obsidian, plus slides, scans and photos
- Tracks which concepts you know across every file in a course
- Exports flashcards to Anki (.apkg) on Pro and up, plus Word and print sheets
Limits
- Not a place to write, link or organize notes
- Weekly caps on every plan
