I’ve no problem with using LibreOffice for most of my document needs, but i haven’t found a good substitute for microsoft’s OneNote yet. I mainly use it to plan my RPG games and it helps a lot. What alternatives are there for organizing notes on linux, with similar features to those that OneNote provides?
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 😃
