What is the best linux alternative to OneNote?

I am surprised that no one has mentioned Rnote yet.

It is my favourite newly-created program for Linux. It is a relatively new app which supports annotating files and taking handwritten notes. You can import PDFs, set the page size to infinite or a fixed size (something OneNote can't do), adjust the background to display grids or lines or dots or nothing with any spacing you like, input text with your keyboard, .... It is available on Flathub for easy installation.

The only major downside is the following: Disclaimer: The file format is still unstable. It might change and break compatibility between versions.

For text-based notes I use Obsidian.
It isn't open source, but it writes standard markdown files to disk, so I can switch programs whenever I like and I am not locked into the Obsidian ecosystem with my notes. That was the main reason why I decided against using Joplin, especially after my experience with converting recipes from Nextcloud Cookbook to markdown ...
In general I am always trying to find a simple file-based solution for whatever I need to do. I want to be able to sync it with Syncthing instead of something fancier that requires a centralised web server or even relies on a cloud service.
- Did you know that you can even sync your note using git and thus a git remote server for syncing? It even works with iOS 😃
- Synching works but if you have a server, Obsidian live sync is fantastic and seamless.
- Amkng all note taking apps, FOSS or not, online and offline, Obsidian still holds the top spot unmatched. I don't even dislike to admit it anymore. It's just that good and really has almost everything.
oh my god, this looks like the note app i've wanted for so long on linux!!
it's still missing some text formatting features imo, but maybe i could hack those in a submit a patch… definitely keeping on my radar! thank you!
- Haha, that's what I was thinking as well when I first discovered it. Glad you found it through my post!
  I took my handwritten notes with PDF Annotator in a Windows VM for over three years ...

I was asking a similar question a few months ago, and my search turned up Joplin. It's a free, open source app that works across multiple platforms and can sync data through a cloud service, either through Joplin's own cloud storage or through a third-party cloud storage like Dropbox.

Thanks! I'll check it out.
- I use and enjoy Joplin. It's much less feature-rich than OneNote, but if you're predominantly using it to make text-based notes it does that with aplomb. I enjoy the cloud syncing, which is very useful combined with the fact that there's an Android app (so I can access my notes on the go).

You might want to explain the features of OneNote, particularly the exact ones that you want. I get the impression that most people don't know its organization structure.

My short input: it's not just note taking. It's has a tiered level of organization for the notes to categorize and quickly move about. The example I read was like it's set up like you have multiple binders, with dividers in each, and pages (notes) within those. The page is very open ended, you can add text boxes in any spot, mixed with pics in any spot.

Your input is very accurate. Being able to write notes freely anywhere on the page, draw on it, attach images, links, etc is a big part of it, but one of the most important things to me is organizing different pages into dividers/binders like you said.
I set up various sections for quests, locations, npcs, etc, for my rpg worlds, and need it to be well organized and be able to link to different sections within the same binder. I also like to color code everything.
- You should check out Affine.pro then. It's FOSS and you can draw anywhere, it's one of their selling points.
Thank you.
We are encouraged to use the Microsoft office suite if tools at work, and I still haven't figured out how to use OneNote to improve my life.
- I use onenote at work for all my notes. tabs and individual pages let me organize things so nothing is too long to scroll and find what I need. I can put text, screenshot, and hyperlink (to another part of one note or outside link), and a link to a pdf or excel file. I can add check boxes to whichever line items.
  once I've got a nice set of notes, I can share either the entire notebook, the section, or just that page with the next person. or if they're a bit of a luddite, I can print it out and maintain format (mostly). the most recent version broke emailing a page, but if you're still running an older version of one note, it embeds it, with formatting, without being a pdf.
  got something you need to paste in all the time? I've got one page where each text box is one copy/paste comment. clicking the header automatically selects all the text in just that box.
  like OP, I tend to use one note at home for D&D, but if I can find something just as good I'm happy to try it. work leaves me with MS Office.

I looked at Joplin and Obsidian for the kind of notetaking I do and settled on Obsidian. To be honest, both have more features than I use. I like Obsidian because it's based on Markdown, so you're not tied to some oddball file format. But you should try them out and see which one fits your work style.

Joplin also uses markdown, and it has the advantage of being open source.
- ...in a database file. That and the awful android app had me look elsewhere. Too bad really, FOSS and self host options with it are great.
- And can sync to webDAV
I recently settled on Obsidian too. It's proprietary software, but the text files themselves are in simple markdown and readable in a text editor. Additionally, you can sync across multiple devices using their paid service (which works flawlessly for everything) or set up sync yourself for free if you know how to host a couchdb instance yourself (works perfectly for everything except iOS, apparently).
The plugin support was baked in from the start so it's extremely flexible.
- I wasn't worried about it being proprietary until I saw the founder reasoning for not having the source be open under a nonpermissive licence.

  I decided to go with logseq because of it.
  It also syncs with all my devices using my own servers, instead of needing to trust obsidian/logseq.
- You can also use SyncThing, works great.
Obsidian is my go to for D&D.
They still sprinkle a bit of their own stuff into the markdown but it's generally usable outside.
Thanks for the suggestions! I'll see which one works best for me.

I'm not sure what features of OneNote you are talking about, but maybe logseq will suit your needs.

I switched from OneNote to Logseq. Its feature set is pretty much completely different, but in the end I realized it's fine with me and resulted in my notes being more useful.
The main downside that I see now is that it's kind of slow - much faster than the Electron version of OneNote was last time I used it, but slower than old native OneNote app or Obsidian. Otherwise its main differences from Obsidian are that in Obsidian the basic building unit is a page, whereas in Logseq it's a paragraph (and, usually, its sub-paragraphs - it's an outliner), which Obsidian can only do with plug-ins and not as seamlessly, and that with Obsidian you pretty much need to use community plug-ins, whereas with Logseq a lot of the functionality is built-in.
It's open-source and uses markdown, not completely standard, but close enough for the files to be entirely usable if Logseq ever dies. Its community is smaller than with Obsidian, which is a downside, but it's not exactly obscure either.
Really probably the most important thing about Obsidian and Logseq is to read an article or watch a video about how automatic backlinking works. It's especially useful for something like Zettelkasten, but it also works for more "normal" approaches as well as concepts like Getting Things Done.
Both are OK tools and are similar in many ways, but they're quite different from OneNote. Downside of both is that synchronization between devices sometimes creates issues unless you use their paid service.

I use logseq and notesnook.

I absolutely second logseq. Would you mind elaborating why/how you use notesnook in addition?
Thanks in advance!
- I've used both, honestly can't justify the price of notesnook after using logseq. I'm in the process of switching over entirely to logseq.
  I will say though that notesnook is a great alternative to Evernote and OneNote that is private and secure. I just don't use its features enough to justify using it over logseq and syncthing.
I absolutely second logseq. Would you mind elaborating why/how you use notesnook in addition?
Thanks in advance!

+1 for Saber. Just found out about it from this comment and it's exactly what I was looking for

Probably logseq or Obsidian, but... if you like plain text and really need customization you might go with what I use: emacs + org-roam

Setup Trilium and use the Firefox extension to save screenshots or the whole page to it automatically which I love.

I'm feeling old. I have a folder called Notes with a directory hierarchy with text files in them. If I want to edit something, I navigate to the appropriate directory and type "vim -S". If I want to get to them remotely (which I haven't really needed) I would SSH in to my system with whatever terminal emulator I had available.

You might look at these relative newcomers to this category of app...with some caveats for why I haven't switched from Obsidian.

Acreom - Not open source yet, but planned. Flat markdown files like Obsidian and Logseq. Dealbreaker for me is that in order to use the app on Android, you have to sign in with Google, Apple, or Github and use their cloud for sync. I'm trying to convince the dev to allow their "local first" mantra to permeate all versions of the app regardless of platform. He is very receptive, so we'll see. If they do, I can see myself switching to Acreom instead of continuing with Obsidian. But that's the beauty of open file format, you can pack up and leave very easily!
Notesnook - Is FOSS. But not self-hostable yet. That is on their roadmap. Potential dealbreaker is that it doesn't support markdown, rather shortcuts that behave similar to markdown syntax. As a result of that and their E2EE, the file format is not as open as Obsidian and others that use simple .md files.

There's a program called cherrytree that I think is very underrated. It's probably not a 1:1 replacement for OneNote but I recommend checking it out in case it fulfills a similar but different need.

Some which I can think out of my head are : Joplin Trillium Logseq Notion Obsidian Anytype

If you need to draw, I would look into notion and obsidian.

I ended up going with obsidian. I wanted absolute portability I needed multiplatform support. I hadn't heard of Joplin at the time I made my choice, but I can say I'm happy with Obsidian and I like how their documentation is dog-fooded and useful in that form.

Joplin is very advanced

This came up a few days ago in another community, and it sounds like the poster may have actually had a similar use-case to your own.

I'm open-source; check me out at GitHub.

Joplin self hosted on a NextCloud instance!

Only because self hosting is satisfying and fun. You can have your Joplin notes synced on OneDrive as well.

On the windows side of things (at my job) i dumped onenote for cherry tree. Its on portable apps website.

Not sure for linux. I run linux at home but only need one note- like programs at work.

1 for Cherrytree, I can even recommend it on Linux. The tree structure makes it so much better to sort things than OneNote with the limited depth.

I use the Notes feature of my Nextcloud instance.

My own use for OneNote was mainly drawing/hand written notes using a drawing tablet. For that use case, I have replaced it with Xournal++

For other notes written with the keyboard, I use simple local markdown files.

All my notes are synced between computers with Syncthing

10+ years ago there was something called Basket Note Pads that had the same blank canvas style note taking that onenote has now.

My heart broke in two when the project died because the metaphor wasn't popular at the time. It'd be so well positioned if it had stayed in development until today.

I only really use the web version of it in Linux but I dumped OneNote for notion.

I have some scripts that use their API to send notes from the command line to a db page and some nvim mappings that I'm trying to get to send my buffers to a page but that part is problematic still.

I looked at obsidian but never really tried it out. I don't like the limits notion has but it's much faster for me to find my notes than OneNote. I have a metric fuckton of notes

Rnote is currently the best for handwritten notes in my opinion, but its organization is minimal. I have never found a 1:1 replacement for OneNote, but luckily I no longer need it desperately like I did a decade ago.

I want to like libre office, but every time I have tried to use it, it ended up crashing eventually

Obsidian could work, its a markdown editor but I doesn't have any handwriting or drawing support, also its sync feature costs money but you can use nextcloud or github to sync your stuff anyway. An opensource alternative would be logseq but I prefer Obsidian

Joplin.

I've tried Joplin, Logseq, and Obsidian. The best one was Obsidian but it's not FOSS and is getting bloated over time.

I'm settling on zk now. This small command line utility solves almost all of the note managing needs for me.
Double links and tags make me forget about these "infinite free board" functionalities in OneNote: turns out they tend to be used inefficiently. Graphical sketches can be embedded in markdown or linked to a drawn picture.

The best thing about zk is that its notes consist of plain text and no extra tracking data is required outside of the file (unlike any others above), which means it's absolutely free to pair it with / move on to other tools when needed, or working temporarily without the support of it.

I'm new to windows as a service desk guy and one note is the only thing I have available. I just wish I knew how to get the best out of it for templates I throw into notes and incidents.

Siyuan is probably the most advanced note taking app out there right now. Affine.pro is also a good one Appflowy is also good. All are FOSS.

Siyuan looks too good to be true.
- I'm using it and it's pretty good. It's arguably too feature rich though. I mean that in every right click you have like 20 options. It's overwhelming.
  Also I use the cloud sync and every few days something doesn't sync properly when you're typing and it asks you to re-sync. And so you have to wait a minute while it re-builds the entire index. It doesn't happen often but when it does it's annoying.
