Quick answer: for most students, the best note-taking app is OneNote if you handwrite or annotate slides, and Notion if you want your notes, reading lists, and assignment deadlines in one organized system. Both are free for the features students actually use. Below we compare the five strongest options for lecture notes, revision, and staying organized — and if you want AI to help summarize and quiz you on those notes, see our guide to AI tools for students.

Microsoft OneNote: best for lecture notes Free
OneNote's freeform canvas is the closest thing to a paper notebook: click anywhere and type, draw diagrams with a stylus, record audio alongside your notes, and paste lecture slides to annotate directly. Notebooks, sections, and pages mirror how courses are structured, so one notebook per semester keeps everything findable.
Best for: students who handwrite on a tablet or annotate PDFs and slides. Watch out for: the interface is busier than newer apps, and syncing depends on OneDrive. It is completely free with a Microsoft account — verify current details on OneNote's official site.
Notion: best for organization Freemium
Notion combines notes, to-do lists, databases, and calendars in one workspace. A typical student setup is one page per course with embedded databases for assignments, deadlines, and reading lists — everything searchable and linked. The free plan covers unlimited personal pages, and Notion offers a free Plus plan to eligible students and educators who sign up with a school email address.
Best for: students who want one system for notes, tasks, and deadlines. Watch out for: Notion's flexibility is a trap for some people — spend your time studying, not decorating your dashboard. If you mostly write long essays, our Notion vs Google Docs comparison explains where each tool fits.
Obsidian: best for revision Free for personal use
Obsidian stores notes as plain Markdown files on your own device and lets you link them together. For revision, that linking is the killer feature: connect "photosynthesis" to "cell respiration" and you build a map of the course instead of a pile of disconnected pages. The graph view shows how topics relate, which is genuinely useful when reviewing for exams.
Best for: students revising interconnected subjects and anyone wary of lock-in — your notes remain readable forever. Watch out for: no built-in collaboration, and syncing between devices requires either the paid Sync add-on or your own cloud folder. Students use it free; check Obsidian's official site for license terms.
Google Keep: best for quick capture Free
Keep is the fastest way to get a thought out of your head: a sticky-note wall with reminders, labels, and checkboxes. It will not replace a real notebook for lectures, but it is excellent for capturing assignments the moment a lecturer mentions them, and everything syncs instantly with your Google account.
Best for: quick capture and simple checklists. Watch out for: no real formatting or folder hierarchy — long-term notes outgrow it quickly.
Apple Notes: best for Apple users Free
If you own an iPhone, iPad, or Mac, you already have Apple Notes — and it is far better than its reputation. It supports handwriting with Apple Pencil, document scanning, folders, tags, and shared notes for group projects, all syncing through iCloud.
Best for: students fully inside the Apple ecosystem. Watch out for: there is no proper Windows or Android version, so switching platforms later is painful.
How to choose, by study style
- You handwrite or sketch: OneNote on any tablet, or Apple Notes on an iPad.
- You want one system for everything: Notion — notes, deadlines, and tasks in one workspace.
- You revise by connecting ideas: Obsidian's linked notes beat linear pages for exam review.
- You just need to remember things: Google Keep for capture, plus a real app for lectures.
Whichever you pick, commit for a full semester before judging it. Consistency beats features — a point we repeat in our roundup of the best productivity tools. Every app here also appears in our guide to free productivity tools.

Frequently asked questions
What is the best free note-taking app for students?
OneNote is the strongest free option for most students: the full app costs nothing, it works on every platform, and its freeform canvas suits handwritten lecture notes. Notion's free plan is better if you want notes, tasks, and deadlines in one organized workspace, and eligible students can get Notion's Plus plan free with a school email.
Is it better to take notes by hand or in an app?
Research generally favors handwriting for understanding, because summarizing by hand forces you to process ideas rather than transcribe them. Tablet apps like OneNote and Apple Notes give you the same benefit digitally: you handwrite with a stylus but gain search, backup, and sync. Typing is fine for fast lectures, as long as you paraphrase instead of transcribing word for word.
Can students get Notion for free?
Yes. Notion's standard free plan already includes unlimited pages for personal use, and Notion offers a free Plus plan to eligible students and educators who register with a valid school email address. Check Notion's official education page for current eligibility rules before signing up.
Which note-taking apps work offline?
OneNote, Obsidian, and Apple Notes all work fully offline because they store notes locally and sync when you reconnect. Notion has historically required a connection for most work, though it has been improving offline support — check its official site for the current state. Google Keep caches recent notes on mobile but is primarily a cloud app.
