Which app should you use? [2025]

A book, an app, the next billion-dollar idea: everything starts from a note. Notion and OneNote are both top-notch note-taking apps, but each has its own way of handling your notes. 

I’ve been a Notion convert for the past several years, and I used OneNote as I was trying out note-taking software. I dove back into OneNote for this comparison and spent time comparing the two apps to help you figure out which one makes the most sense for your note taking.

Notion vs. OneNote at a glance

The basic difference between the two apps is that OneNote helps you keep rich notes in flexible digital notebooks, while Notion focuses on upgrading your notes with structured databases, letting you build your productivity system on top of them. 

Keep reading for details on each app, but here’s a quick overview.

OneNote for beginners, Notion for tinkerers

When you think of Microsoft Office, the apps that steal the show are Word, PowerPoint, and Excel. People don’t tend to talk about OneNote, but they should: it’s really powerful for taking notes and keeping them organized. Chances are it’s already installed on your Windows PC, eager to burst out of your Start menu.

If you’re just getting started in the world of note taking, it’s a solid choice to begin with. It follows the same logic as physical notebooks: add new notes, place them inside a notebook, and then separate those notes into sections.

OneNote has a similar user experience to other Office apps, so it’s easy and intuitive to pick up if you’re used to that software suite. When you open the desktop app, you land on the last page you were working on. From there, you can add new pages, sections, or switch between notebooks. At the top, you’ll find the familiar Office-style menu with all the controls. The experience is slightly different when accessing from your browser, as the interface is more modern, but it’s still easy to find your way around.

Notion is also easy to use, but unlocking its full potential takes much more time. It has an open-sky feeling when you land on the white page, letting you customize nearly anything about your personal knowledge platform.

On a path to being a flexible all-in-one app, Notion adds sets of specialized features to move work forward:

• Project management features that track tasks, subtasks, and timeline views.

• Notion Calendar to place your tasks on a calendar, fully synced with your workspace. It also includes a simple meeting scheduling tool.

• Notion Mail (coming soon as of this writing) will apply the building-block philosophy to the email experience.

• Database automations that can change properties based on actions, doing things like sending Gmail emails when important changes are detected.

• Formula-based customization to add a bit of display logic to your databases, letting you create and work with variables, pulling information from your workspace.

If you just want to focus on notes, OneNote will be great for you. But if you like to constantly ask yourself, “how can I improve my note-taking setup?”, you’ll be able to iterate on that question with Notion every day.

OneNote for freeform note-taking, Notion for productivity systems and collaboration

One important aspect of a note-taking tool is being able to capture your ideas—no matter what form they come in. Not everyone thinks in text sentences: sketches, audio, recordings, and even mathematical equations are all valid ways to express what you’re thinking.

OneNote’s desktop app, available for both Windows and Mac, is impressive in the options it offers:

• Rich text notes, letting you choose fonts, colors, and your own heading styles

• Drawing tools, including free draw with thickness and color controls, shapes, and lasso select—making it almost a mini MS Paint

• Version control for your notes, with editing history for multiple authors collaborating on the same note

• Spell check, thesaurus, translation, language setup for proofreading, and an accessibility checker to make sure everyone can absorb the content

• Audio and video recording

• Arithmetic features (OneNote calculates the answer to 334+626, tells you the square root of 15, and keeps track of equations like the Pythagorean Theorem, if you’re super into triangles)

• Dictation that turns anything you say into text (it’s surprisingly accurate)

I like how you can paste anything into a note and it sits there like a Word text box. It’s really flexible: you can resize and move content anywhere on the white space, which feels freeing and helps you visualize your thoughts with greater clarity. If you usually lose references, OneNote also keeps track of where you pasted quotations from by keeping the website link together with the content.

When you’re out and need to pen something down quickly, the OneNote mobile app is fast and can get a keyboard in front of you within two taps after you unlock your screen. The formatting is a bit limited on mobile, which is understandable, but you can add content easily and make it beautiful later on.

Notion isn’t as agile for note-taking. You can keep your notes inside pages, adding content blocks—text, images, and other formatting elements—and dragging them around to create your own layouts. The elements snap together into a kind of grid, which is amazing to create custom dashboards and richer notes, but offers a little less flexibility when compared with OneNote.

Notion’s freedom lies elsewhere. When you have too many notes to keep track of, you can dump them inside a database. Then you can add properties to each note to help keep them organized. Let’s say you have 100 notes, and 40 of those are about email marketing: open a note, create a property, and label all remaining notes accordingly. Then, create two filtered database views: one for all your email marketing notes and another for the general ones.

You can apply this method to any other details you want to track: status, due dates, or assignees, for example. And the same way you can keep track of notes, you can also add databases for tasks, books, or projects.

After you set up a couple of views, the next step is creating relationships between pages. Let’s say that you’re working on two projects and want to associate notes you’re taking with the respective project. Add a relation property between your notes and the projects you want to link, and now you’ll be able to see a list of connected notes when you open the project page.

Once you get the gist of building these links, Notion helps you break linearity, bringing this platform from simple note-taking to a comprehensive knowledge management system.

After you build your custom productivity system, you can bring your team into it and collaborate together. You can add comments and mentions on each page and each block on the team workspace, and see everyone editing and updating in real-time. You’ll be able to do a lot more with fewer emails and meetings.

OneNote has password-protected notes and offline mode

If you have good digital security habits, there’s a high probability your notes will be safe online. But when you want to be absolutely sure that a note will only meet your own eyes and not anyone else’s, OneNote lets you add password protection to any section inside a notebook. This will keep the information safe even if someone gains access to your device without your consent. Once locked, content will stop appearing in searches, keeping it private at all times. (Keep in mind: setting passwords is only available on OneNote desktop.)

The other good thing about OneNote is that it works offline, syncing your notes to the cloud once you’re back on. This means that you don’t need to worry about long flights or outages anymore—just download the notes you want access to ahead of time.

Notion has great security standards to keep prying eyes out, and it also has good controls to set up privileges if you’re running a team workspace. You can hide or show anything based on the permissions you set up, ensuring your team can only see what they need to see. But password protection for specific notes or databases isn’t available, and while there’s demand for offline mode, it doesn’t seem like it’s coming any time soon.

Notion offers unlimited cloud storage

The first thing you’ll notice about OneNote is that it’s free. All the features are free to use, but let’s get rid of the big asterisk in the room: there isn’t limitless cloud storage. Your notes are stored in OneDrive, Microsoft’s cloud storage service, and it’s limited to 5GB on the free plan. If you want more storage, you can increase your quota by subscribing to a Microsoft 365 plan, giving you access to the full range of Office apps, too.

When you subscribe to a paid plan, OneNote gets shiny cosmetics, mostly. Want to draw with sparkly ink? Welcome to the land of dreams. However, there’s one useful feature that’s unclear whether it’s free or premium: dictation. Even though Microsoft’s support page says it’s paid, I was able to use it for free while testing without paying or hopping on a trial.

Notion is different. It’s a paid app with a very generous free plan for individual use. When you get a Free tier account, you can:

• Access all the content blocks, organization, and collaboration features

• Keep track of changes with the 7-day page history

• Invite up to 10 people to collaborate with you on your pages

• Upload files up to 5MB in size

• Unlimited cloud storage

You can then upgrade to the Plus plan, which will notably remove the 5MB file upload limit, let you access 30-day page history, and allow you to invite up to 100 people to your pages.

So Notion limits the upload file size on the free plan, which is a drawback, for sure. You’ll have to resort to a lot of image-compressing services—I plead guilty—or breaking stuff up into tiny bits to make it fit. All that goes away when you subscribe to the paid plan. But free or paid, the upside is that you’ll never run into a wall as far as storage is concerned. While OneNote may last you for a very, very long time—especially if you’re only creating text notes—that wall is coming.

Both have robust AI features, but Notion edges ahead with Q&A

Notion was one of the first apps to launch its AI features, shortly after ChatGPT broke into the mainstream. First, it deployed generative AI: when you put the cursor on a new empty line, pressing the spacebar will bring up a range of AI actions.

• Continue writing will, unsurprisingly, continue writing where you left off, following your train of thought.

• Summarize and Find action items work with the content on the current page. You can either generate them with the AI command, add a new block that will automatically do it for you on the page, or use a database AI autofill rule for populating your database properties.

• Create flowcharts and tables from a prompt.

• Translate will get your work into other languages.

• Fix spelling & grammar and a few other options serve as basic text editing tools.

• Draft with AI options let you start writing a blog post, essay, or creative story.

Powered by OpenAI technology, it feels like ChatGPT without the chat experience, an AI inside your document editor.

These generative AI features for writing are useful, but Notion Q&A takes it a step further, giving AI-generated answers based on the content of your workspace. Sure, it sometimes misses a few pages and details I’m sure I have in my account. But it’s generally solid, and you can connect it to your Google Drive, Slack, and GitHub to generate answers based on the files you have there as well. If you don’t get it the first time, try asking again from a slightly different angle.

The AI features in OneNote dropped this year. Another arm of Microsoft Copilot, you can access them by clicking the Copilot button at the top of the screen. Once open, you can write prompts to generate text, rewrite your notes, generate ideas, and plenty more. It doesn’t have AI search features like Notion does, remaining good for content generation but not so much for retrieval.

While Notion offers a few free credits for you to explore, this toolbox is subscription-only for OneNote Copilot. You’ll have to buy Microsoft Copilot, but the upside is that similar features will be available in Word, Excel, and other Microsoft apps.

In the end, both apps are equivalent in the AI content generation and editing, but Notion edges ahead with its Q&A tools integrated with external data sources, making information slightly easier to browse and digest.

Both apps integrate with Zapier

Both Notion and OneNote have deep integrations with Zapier, which means you can connect them to thousands of other apps in your tech stack. Make either app an information hub by automatically turning notes into to-do list items, turning emails and calendar events into notes or database items, and taking care of all the other tasks that take you away from your core work.

There’s also certainly a case for using both apps together: OneNote as the frontline content generation app and Notion as the organization backliner. If you go that route, you can use Zapier to be sure they make accurate, automated passes between them.

OneNote vs. Notion: Which should you choose?

Once you drill down on what makes OneNote and Notion unique, it gets a bit hard to make an apples-to-apples comparison. If you want a flexible app to record any kind of idea that pops into your head, OneNote wins; if you’re looking to integrate notes with other processes and keep your team in the loop, Notion is more versatile.

You should go with Notion if you’d like to build your own personal productivity platform, you need to collaborate with others, or you want to keep more data on the cloud.

You should go with OneNote if you want a powerful note-taking app ready to use straight out of the box, you need to capture ideas in more different formats, or you’re just getting started in taking notes and need a simpler tool.
