Best Note-Taking Apps Compared: Notion vs OneNote vs Obsidian

Choosing the best note taking app for students in 2026 usually comes down to three names: Notion, Microsoft OneNote and Obsidian. Each has a devoted following, each is genuinely free to start, and each suits a different kind of learner. The wrong choice costs you more than money — it costs you the friction of switching systems mid-semester, when your notes are scattered across tools that do not talk to each other. This comparison gives you the honest trade-offs: what each app actually does well, what it charges when free stops being enough, and which one fits how you study.

All pricing below is in US dollars (these tools bill in USD) and was current at the time of writing — always confirm on the official pricing page before paying, because plans change. Let us start with what actually matters in a student note-taking app.

What Matters in a Student Note-Taking App

Before comparing features, get clear on your own needs. The best note taking app for students is not the one with the longest feature list; it is the one that matches how you think and work:

  • Capture speed. Can you get an idea down in under five seconds, in a lecture, on your phone? Slow capture kills note-taking systems.
  • Organisation that survives a semester. Twelve weeks of lectures, readings and assignments per subject, times four subjects, creates hundreds of notes. Folders alone do not scale; you need search, tags or links.
  • Offline access. Campus Wi-Fi fails, regional internet drops out, and exam revision happens on trains. Your notes should open without a connection.
  • Price over a full degree. A “cheap” subscription at $10 a month is $360 over a three-year degree. Free matters when you are a student.
  • Getting your data out. Your notes are your intellectual property. If an app makes exporting painful, you are renting your own thinking.
  • Study-specific features. Things like handwriting support (for diagrams and maths), audio recording synced to notes, flashcards, and templates for lectures or readings.

With those criteria in mind, here is each contender.

Notion: The All-in-One Workspace

Notion is the app people mean when they say “second brain”. It combines documents, databases, task lists, calendars and wikis in one workspace, which makes it uniquely good at running your entire student life — not just notes, but assignment trackers, reading lists, grade calculators and semester planners — in a single system. A lecture note can link to the assignment it relates to, which sits in a database sorted by due date. For students who love building systems, nothing else comes close.

What students get for free

Notion’s free plan is genuinely useful: unlimited pages and blocks for an individual, basic forms, and the Notion Calendar. For solo student note-taking, many people never hit a paid wall. But there is a better deal specifically for students: the Education Plan, which is free for students and educators at accredited institutions who sign up with their school email. It provides Plus-level features — unlimited file uploads, 30-day page history and expanded collaboration — at no cost. Several independent breakdowns confirm the offer details (see this Notion student plan breakdown for the current terms). If you are at an Australian university, your .edu.au email address is exactly what this is for.

When you would pay

Beyond the free and education tiers, Notion Plus costs US$10 per user per month billed annually (US$12 month-to-month), and Business is US$20 (US$24 monthly) — that is the tier that includes the full Notion AI suite. For an individual student on the Education Plan, paid tiers are almost never necessary.

The trade-offs

Notion’s weaknesses are real. It is online-first: the offline mode exists but is limited, which matters if your internet is unreliable. Large databases can slow down. The flexibility is a double-edged sword — a blank workspace invites endless tinkering, and plenty of students have lost weeks to building the perfect system instead of studying. And your notes live in Notion’s proprietary format on their servers; exporting is possible but not as clean as plain files. If you choose Notion, start from a finished template rather than a blank page, and resist the urge to redesign your system every fortnight.

Microsoft OneNote: The Free Workhorse

OneNote is the quiet achiever of this comparison. It is completely free with a Microsoft account — no feature tiers, no upsell — and it is deeply integrated with the Microsoft 365 ecosystem many Australian universities already provide to students. If your uni gives you a student Office 365 account, OneNote syncs across your devices with generous cloud storage included.

Where OneNote wins

For handwritten notes, OneNote is the best of the three by a clear margin. Its ink support on tablets (with a stylus) feels natural: you can handwrite maths working, annotate PDF readings, draw diagrams and convert handwriting to text. For subjects heavy in equations, sketches or annotated diagrams — engineering, maths, anatomy, chemistry — this alone can settle the decision. It also records audio synced to your notes, so tapping a paragraph jumps the recording to the moment you wrote it — brilliant for reviewing confusing lectures.

The notebook/section/page structure mimics physical binders, which makes it instantly comfortable for students transitioning from paper. Sharing a notebook with a study group is straightforward, and real-time collaboration works well.

The trade-offs

OneNote’s organisation is its ceiling: beyond notebooks, sections and pages, there is no real database functionality, no backlinks, no graph view. Once you accumulate hundreds of notes across a degree, finding things relies heavily on search, which is good but not structural. The interface, while improved, still feels less modern than its rivals, and the mobile app is functional rather than delightful. Export options exist but are clunky compared with plain-text formats. OneNote is a superb digital binder — but it is a binder, not a knowledge system.

Obsidian: The Local-First Power Tool

Obsidian takes the opposite philosophy to Notion: instead of everything living in the cloud, your notes are plain Markdown text files stored in folders (“vaults”) on your own device. Everything else — the bidirectional linking, the visual graph of how your notes connect, the 2,000-plus community plugins — is built on top of those humble text files. The result is fast, private, offline by default, and future-proof: your notes remain readable in any text editor, forever, with no subscription required to access them.

The price: genuinely free

This is Obsidian’s headline feature. The complete application — unlimited notes and vaults, graph view, Canvas whiteboards, all core features and the full community plugin catalogue — is free for personal use, with no account required. The paid items are optional services around the app: Sync (official end-to-end encrypted cross-device sync) at US$4 per month billed annually or US$5 monthly, and Publish (turn notes into a website) at US$8 per month annually or US$10 monthly per site. Education and non-profit users get 40% off those services. Many students skip Sync entirely and sync their vault through iCloud, OneDrive or Dropbox for free — a common workaround, though occasionally less reliable for very large vaults.

Where Obsidian wins

For students who think in connections, Obsidian is unmatched. Writing a note about, say, Keynesian economics and linking it to your notes on the Great Depression, fiscal policy and last semester’s macroeconomics unit builds a web of understanding that mirrors how memory actually works. The graph view makes those connections visible. The plugin ecosystem adds flashcards with spaced repetition, calendar-based daily notes, citation management for research students, and kanban boards — essentially, the community builds whatever the core app lacks.

The trade-offs

Obsidian has the steepest learning curve here. Out of the box it is a blank Markdown editor; the power comes from configuration, and configuring takes time you could spend studying. Collaboration is weak compared with Notion or OneNote — it is a personal tool first. The mobile apps, while much improved, still lag the desktop experience for plugin-heavy setups. And if you want the official encrypted sync, that is a subscription after all. Choose Obsidian if you enjoy tinkering and want to own your notes outright; avoid it if you want something that works perfectly five minutes after installing.

What About Apple Notes, Evernote and Google Keep?

Three apps that often come up deserve a quick verdict. Apple Notes is genuinely good now — free, fast, excellent handwriting support on iPad, and deeply integrated if you live in the Apple ecosystem. Its weakness is portability: it works best inside Apple’s world and offers little for Windows or Android users. Evernote pioneered this category but has raised prices and restricted its free tier over the years; most students are better served by the three apps above. Google Keep is a fine sticky-note app for quick capture but not a study system — use it for fleeting reminders, not semester notes. None of the three beats our top picks for serious student work, but Apple Notes in particular is a legitimate choice if you are all-in on Apple devices and want zero setup.

Switching Apps Without Losing Your Notes

If you are mid-degree in the wrong app, switching is less painful than it looks — provided you do it once, deliberately. Export everything from the old app first (Notion exports to Markdown and PDF; OneNote to Word and PDF; Obsidian is already plain files, so just copy the vault folder). Then import into the new app in small batches, one subject at a time, cleaning as you go — migration is a rare chance to delete obsolete notes rather than carry digital clutter forward. Do not try to recreate your old folder structure perfectly; set up the new system’s native organisation (databases in Notion, vaults and links in Obsidian, notebooks in OneNote) and let the old structure go. Budget a weekend, keep the old app installed read-only for a month as a safety net, and then delete it. The students who get stuck are the ones running two systems indefinitely — commit to the move.

So Which Is the Best Note Taking App for Students?

It depends on the student. Here is the honest decision guide:

  • Choose Notion if you want one app for notes, assignments, deadlines and life admin; you collaborate on group projects; and you have reliable internet. Claim the free Education Plan with your university email on day one.
  • Choose OneNote if you handwrite notes on a tablet, your subjects involve diagrams or maths working, your university provides Microsoft 365, or you want the simplest thing that works. It is the lowest-effort, highest-reliability option.
  • Choose Obsidian if you are building knowledge across a multi-year degree, you care about owning your notes as plain files, you work offline often, or you enjoy customising your tools. Budget a weekend to learn it properly.

And here is the advice nobody gives: you do not have to marry one app. Many successful students use OneNote for lecture capture and handwriting alongside Obsidian or Notion as their permanent knowledge base. What matters is not the tool but the habit — capture consistently, review regularly with active recall, and organise around retrieval, not aesthetics. The fanciest system in the world is worthless if you never open it during exam revision. Pick the app you will actually use on your worst, tiredest day — that is the real test.

Getting Started: Your First Week With Any of Them

Whichever you choose, set it up for study success from day one. Create one notebook, workspace or vault per subject — never one giant pile for everything. Build a simple template for lecture notes (date, key concepts, questions to follow up, action items) and use it every time; consistency makes revision dramatically faster. Sync to at least two devices so your notes survive a dead laptop, and test that sync before you need it. Finally, schedule a weekly 15-minute review to file loose notes and surface anything you flagged as confusing — this tiny habit is what separates a note collection from a study system. Pair it with a solid planning tool (see our roundup of the best planners and organisation tools for students) and your semester admin is essentially handled.
