Notion vs Obsidian vs Roam: The Honest Second-Opinion for College Note-Takers

A junior at UCL spent a week last October migrating four semesters of philosophy notes from Notion into Obsidian, then panicked and moved everything back. Her problem was not the apps. It was that she picked based on a YouTube video, not on how she actually studies. Notion vs Obsidian vs Roam has become one of those debates where people bring pitchforks, and the loudest voice is rarely the one that matches your major, your syllabus, or the way your brain connects ideas at 1 a.m. before a seminar. The three tools are genuinely different, and they reward different types of student thinking. This guide is the second opinion nobody hands out at freshman orientation. It sets aside the fanboy takes, walks through 2026 pricing in USD, GBP, and AUD, and matches each app to real academic use cases. By the end, undergrads in the US, UK, and Australia should know whether to open Notion tonight, pay for Obsidian Sync at $4/month, or commit to Roam Research at $15/month. The wrong pick costs you a semester of friction. The right one compounds into a personal knowledge base you keep after graduation.

Notion vs Obsidian vs Roam: The 90-Second Verdict

Group projects, class trackers, syllabi, tidy dashboards, sharing with a study partner? Notion. Long-term personal notes, offline reliability, no monthly fee, and full control of your files? Obsidian. Research-heavy majors where ideas link across dozens of readings and you think in networks? Roam. That is the frame.

Notion is a database dressed up as a notes app. Obsidian is a Markdown editor that treats your local folder as sacred. Roam is a bidirectional-link outliner built for researchers. Undergraduates who need one tool for classes, side projects, and a job-application tracker gravitate to Notion. Students who write theses, review literature, or study philosophy and history reach for Roam. Anyone who has ever lost cloud data and sworn "never again" ends up on Obsidian.

Notion: The Dashboard That Doubles as a Notes App

Notion is free for students on the Education Plan, which unlocks the Plus tier at no cost with a valid .edu, .ac.uk, or .edu.au email. That upgrade removes the block limit, adds unlimited file uploads, and lets you invite up to 100 guests. Notion AI still costs extra at $10/month ($8/month annual, roughly £8 or AU$15). Group project team plans start at $10/user/month when the education discount does not apply.

Where Notion earns its keep: syllabus dashboards, group project databases, application trackers, and the kind of shared-page workspace where a four-person capstone team can drop files, tag statuses, and comment inline. Templates from the Notion community handle everything from a 15-week semester planner to a job-hunt CRM. The killer feature for undergrads is databases as views: the same reading list appears as a Kanban for progress, a calendar for due dates, and a filtered table for exam week.

Honest weakness: Notion is web-first, so offline access is patchy and PDFs open as links, not annotated documents. If your Wi-Fi at the library dies, so does your ability to open lecture notes. For pure focused reading and writing, Obsidian is faster.

Obsidian: The Vault You Actually Own

Obsidian is free forever for personal and educational use. That includes commercial coursework, capstones, and internships as long as you are the sole user. Sync (their end-to-end encrypted service) runs $4/month billed annually ($48/year, about £38 or AU$72). Publish for public sites is $8/month. Everything else, including 2,000+ community plugins, is free. Notes live as plain Markdown files on your laptop, so if Obsidian ever disappears, your notes still open in TextEdit, VS Code, or any editor made in the last 40 years.

Sweet spot: students who want a note system that outlives college. A senior at ANU switched from OneNote to Obsidian sophomore year and now runs a 3,400-note vault covering four majors, personal reading, and a research assistant job. The graph view is the party trick, but the real value is the file-over-app philosophy. When you graduate and your .edu Notion perks vanish, Obsidian keeps working exactly the same.

Downside: no collaborative editing. Group projects still need Google Docs or Notion. And there is a real setup curve, mostly around picking the right five plugins (Dataview, Excalidraw, Tasks, Templater, Advanced Tables) instead of the tempting 60.

Roam Research: The Networked-Thought Engine

Roam is $15/month billed monthly, $165/year annual ($13.75/month, about £132 or AU$249 per year), and there is a Believer Plan at $500 for five years. There is a 31-day free trial, no free tier. That price tag scares off casual users, which is arguably the point: Roam wants committed researchers, not tourists.

The pitch is bidirectional linking taken further than any competitor. Type `[[Kant]]` anywhere and every note that references Kant surfaces in his page automatically. Combine that with the daily notes journal, block references, and queries, and Roam becomes a personal Wikipedia that grows as you take lecture notes. A PhD-track sociology major at NYU keeps every reading, every seminar comment, every quote in Roam, and by senior thesis time already has 400+ interconnected notes she can query by tag, professor, or theme.

Weakness: no true offline mode until recently (desktop app helps, but graphs still sync online), a learning curve steeper than Obsidian, and pricing that makes little sense for a freshman taking intro courses. Roam only pays off if you have long, multi-year research to compound.

Notion vs Obsidian vs Roam by Major

Business, marketing, and communications undergrads: Notion. Group projects dominate, and Notion databases handle client trackers, campaign plans, and shared briefs better than the other two. Applied majors also benefit from the Notion AI features for meeting summaries and quick outlines.

Humanities, philosophy, history, and pre-law students: Roam or Obsidian. Roam if you are deep into research and can afford it, Obsidian if you want the same networked thinking without the subscription. English majors writing thesis chapters lean Obsidian; philosophy majors mapping arguments across 30 primary sources lean Roam.

STEM undergrads: mixed. Obsidian with the Dataview, Excalidraw, and math plugins works beautifully for problem sets and lab notes. Computer science students often prefer Obsidian for the raw Markdown and Git-friendly file format. Chemistry and biology undergrads who annotate PDFs might supplement with Zotero or MarginNote.

Premed and medical students: Obsidian for lecture notes plus Anki for flashcards is the dominant stack. Notion works for rotation trackers and application spreadsheets but not for deep learning.

The Data-Ownership Question That Matters More Than Features

Notion stores your notes on their servers. Roam does too. Obsidian stores them on your machine as plain files you can back up to iCloud, Dropbox, or a $30 external drive. That distinction becomes real the first time a service raises prices, changes terms, or has a multi-hour outage during finals week.

Notion had an outage during peak US midterms in October 2024 that locked thousands of students out for hours. Nobody died, but seminar assignments were late. Obsidian users kept writing. If your notes are the operating system of your degree, that resilience matters more than any single feature comparison. Roam has had similar wobbles, though rarer.

What Each App Costs Over Four Years

Notion: $0 for students with the Education Plan, $360 without it if you paid Personal Pro over four years. Notion AI adds $384 over four years at $8/month annual. Obsidian: $0 forever, $192 if you add Sync for four years ($48/year x 4). Roam: $660 over four years at the annual rate, or the $500 Believer Plan (five years, so cheaper). Free is free, but paid tools that survive graduation are the real value calculation.

The Bottom Line

Notion vs Obsidian vs Roam is not a fight over the best app, it is a match between your major, workflow, and long-term data ownership philosophy. Group-heavy business majors thrive in Notion. Independent, keyboard-first note takers thrive in Obsidian. Research-track thesis writers thrive in Roam. Pick based on how you actually work, not on what a Twitter thread said this week. The best note app is the one you open every day for four straight semesters.

Data ownership matters more than any single feature, and it only becomes obvious the first time a service outage or a subscription hike catches you during finals. Undergrads who pick Obsidian rarely regret it. Students who need a shared workspace pick Notion. The rare few who need a networked personal Wikipedia pick Roam. Match tool to real habit, then commit.

Frequently Asked Questions

Is Notion actually free for students, or are there catches? Notion Plus is free for verified students and educators with a valid academic email (.edu, .ac.uk, .edu.au, and many others globally). The plan unlocks unlimited blocks, unlimited file uploads, 30-day version history, and up to 100 guest collaborators. The catch is Notion AI, which still costs $10/month monthly or $8/month annual. Verification is instant with most academic domains and requires re-verification annually.

Which is better for taking lecture notes: Notion or Obsidian? Obsidian wins for pure lecture-note taking. It is faster, works offline, handles Markdown so your fingers never leave the keyboard, and files sync via iCloud or Dropbox at zero cost. Notion is better if you want to layer databases (linked readings, professor tags, exam dates) on top of your notes and share them with a study group. For a solo notetaker in a 90-minute lecture, Obsidian is the tool.

Is Roam Research still worth $15 a month in 2026? For most undergrads, no. Roam is worth the price only if you are doing long-form research (senior thesis, honors capstone, PhD-track work) where bidirectional links compound across hundreds of notes over years. For a freshman taking five intro classes, Obsidian gives 80% of Roam's networked-thinking benefit at zero cost. If you graduate and start a knowledge-work career, revisit Roam then.

Can I use Obsidian for group projects? Not natively. Obsidian is single-user by design, so real-time collaboration is not a feature. Workarounds exist: sync a shared vault via iCloud or Git, but merge conflicts get ugly fast. For group projects, use Notion or Google Docs alongside your personal Obsidian vault. Keep your class notes in Obsidian, keep team deliverables in a shared Notion workspace.

What is bidirectional linking and why do people care? When you link Note A to Note B in most apps, only A knows about B. Bidirectional linking means B also automatically knows A links to it, and shows a backlink. Over hundreds of notes, this surfaces connections you forgot you made: a quote from a philosophy reading appears when you open a related essay draft three months later. Obsidian and Roam both do this natively. Notion added a version but it is weaker in practice.

Which app has the best free tier for a broke undergrad? Obsidian, by a wide margin. It is fully free forever for personal and educational use, including all core features and the entire community plugin ecosystem. Notion's Education Plan is generous but requires re-verification annually and locks Notion AI behind $10/month. Roam has no free tier at all beyond a 31-day trial.

Can I switch between these apps later without losing my notes? Obsidian is easiest: files are plain Markdown, so they open anywhere. Notion exports as Markdown or PDF but the databases lose structure on export. Roam exports as JSON or Markdown and the block references break in most other apps. If flexibility matters, start with Obsidian: your notes stay yours in any future tool.

Do UK and Australian students get the same pricing? Roughly, yes. Notion's Education Plan works with .ac.uk and .edu.au domains at the same free tier as .edu. Obsidian's pricing is USD but flat globally, so £38 or AU$72 a year for Sync. Roam bills in USD too, meaning UK students pay about £132/year and Australian students AU$249/year at exchange rates in 2026. UNiDAYS and Student Beans occasionally list additional Notion or productivity tool discounts worth checking.
