For years, OneNote has been my go-to tool for capturing every thought, note, and project detail. Its robust features made it a digital extension for my brain. However, as my workflow grew to include complex and confidential projects, I found myself longing for more control, a cleaner interface, and a solution that truly feels like my own. Notion felt like a natural upgrade, but since it’s not open-source and lacks self-hosting capabilities, I decided to skip it.

That’s when I stumbled upon Outline. Although it’s geared towards building a team knowledge base, I have found it to be quite effective for personal use as well. Whether it’s UI, privacy, features, or accessibility, Outline ticked all the boxes for my note-taking style.

Outline looks and feels modern

With seamless collaboration

The first thing that struck me about Outline was its modern aesthetic and clean user interface. While OneNote is functional, it often feels a bit cluttered. On the flip side, Outline is not trying to do everything at once; instead, it focuses on making core note-taking and knowledge organization beautiful and efficient.

The navigation is logical with a standard sidebar, and the entire application just feels responsive and well-thought-out.

And that brings me to performance. OneNote sometimes feels sluggish, especially when syncing large notebooks and sections. Outline is blazing fast. The difference is night and day. Pages load instantly, and searching across my entire knowledge base is nearly real-time. Navigating between sections feels snappy and fluid.

The editor itself is a dream to work with, with a slash command and Markdown support. Typing / instantly brings up a menu of options to insert everything from tables and task lists to embeds. I can drop in Figma designs, Loom videos, or even code blocks in no time.

Although OneNote supports collaboration, Outline is built from the ground up to deliver a seamless collaborative editing experience. And it delivers on that. Overall, Outline easily beats OneNote when it comes to basics.

Robust organization techniques

Arrange your docs like a pro

Outline has also nailed the organization. When I open it, I can see my various collections laid out clearly. I have a collection for work projects, personal notes, and even one for a knowledge base.

Every collection comes with an overview, which is essentially a dedicated document where I can put a high-level summary, key links, or a table of contents for that entire collection.

From there, I can start adding documents. These are similar to pages in OneNote, but with far more power and flexibility. I can even create nested documents, pin them for easy access on the Home menu, and even mark them as favorites.

These small features make finding and managing my most critical information a breeze, something I often struggled with OneNote’s less flexible structure.

Templates support

Fly through your notes and documents

Although Outline doesn’t support third-party templates, it lets you create one with a fixed structure. For example, I have a Meeting Note template with headings like Attendees, Agenda Items, Action Items, Discussion Points, and more.

Similarly, for new project plans, I have a template with sections for Project Overview, Goals, Key Milestones, and Potential Risks.

Unfortunately, there is no way to use a template right from a document. You need to head into Settings -> Templates section and duplicate a relevant one. The user experience could have been better here.

Integration with your favorite tools

Slack, Figma, Loom, and more

Outline has seamless integration with the tools I already use daily. This is a huge differentiator from OneNote, which often felt like a walled garden. For example, with Slack integration, I can configure it to post notifications directly into specific Slack channels.

The real power comes with Zapier. If you are not familiar with it , Zapier is an automation platform that connects thousands of web applications. Outline’s integration with Zapier means I can link it to other tools in my digital toolkit and create an automated workflow.

An open-source platform

With self-hosting flexibility

Perhaps the most compelling reason I finally made the switch from OneNote to Outline boils down to two critical factors: Outline is an open-source solution that offers true self-hosting.

The software’s source code is publicly available for anyone to verify. There are no hidden agendas or backdoors. Instead of my notes residing in a third-party cloud, I can deploy and run Outline directly on my own server. This puts me in 100% control of my data.

Setting it up as a container (like with Docker, which I’m quite familiar with) made the self-hosting process surprisingly straightforward.

Frustrated with OneNote? Try this container

The moment it was up and running, I knew my days of relying on OneNote were over. Transitioning away from Microsoft’s note-taking app wasn’t something I expected, but discovering Outline proved to be a pivotal moment. This self-hosted, open-source knowledge base filled the void left by OneNote and elevated my note-taking system.

Of course, it’s far from perfect. One of the irritating limitations is that you can’t sign up for Outline using a personal Google or Microsoft account. It also lacks native mobile apps. There are no drawing tools either. If these limitations are a deal-breaker for you, check out Evernote or Notesnook.
