My One Big Text File
I do all my writing in a text file. Not any text file or “text files.” I mean one single .txt file. All my notes, blog posts, ideas, essays - anything not written in pen or pencil - live in or begin life in this document and its copies. Everything I post online is just a copy-paste. Sounds chaotic, right? Maybe it is, a little. But not as much...

Your one-stop
publication workbench
From idea to publication in one app: Zettlr accompanies you while writing your blog post, newspaper article, term paper, thesis, or entire book.
@Rollerball :
I prefer using separate software for notes and to-do lists.
So, for to-do lists I use Joplin (on the Linux PC).
For long and knowledge base notes I use Zettlr (on the Linux PC) and for quick and encrypted notes I use Standard Notes on the Android Phone (it's available on F-droid).

Standard Notes is a free, secure note-taking app with powerful end-to-end encryption, unparalleled privacy features, and seamless cross-platform syncing on unlimited devices.

Peace of mind with your newfound privacy comes easy with Standard Notes. But there's so much more.
Other apps force you into a rigid structure, making it difficult to truly capture and organize all of your thoughts, ideas, and creations. As a result, you find yourself relying on multiple tools to get the job done, leaving your data scattered and potentially vulnerable.
With Standard Notes, you have a single, all-in-one solution for securely storing and organizing your notes, files, and everything in between. Say goodbye to the hassle of using multiple apps and hello to pure, effortless productivity.
