Welcome to zettelkasten.online.
I first came across Niklas Luhmann's Zettelkasten note-taking system a few years ago and could immediately see its greatness. Having been frustrated with existing systems, I found that highlighting and scribbling did not produce a lasting knowledge base that I could use to strengthen my understanding or turn into anything but a labyrinth of impenetrable notes. But there were several aspects of the Zettelkasten system that limited my interest, the main one being hand-written notes stored in a physical box.
I am afraid I lack space for note-taking like this method and do not enjoy writing with a pen. My handwriting is not particularly good, not because I am unable to write with a pen, but because I have spent my entire professional life typing on a keyboard. The prospect of picking up a pen didn't excite me in the slightest. Furthermore, my life at that time was mobile; I wanted something that would enable immediate note-taking and processing. I would rather not spend five days away from home, only to return to decipher and process my notes. I am afraid I am a product of the “I need it now” world.
I tried to implement some of the techniques with digital writing tools, but it didn't work. The most compelling aspect of Luhmann's system is not the act of adding notes, although both the notes and the structure are essential. Instead, it is the output that I wanted: using my personal notes to help my future self. Without the Zettelkasten structure, this output does not occur.
In 2025, I started to develop Mind Dump, its roots set as a task management platform, but as I explored my different areas of interest, I branched the application into personal knowledge management, implementing a mind map and outliner. One of my fundamental demands of Mind Dump is what I call the “capture surface.” To be a truly useful task manager and personal knowledge manager, capturing notes and data had to be as friction-free as always.
As I progressed, it became clearer and clearer that if I were to reach my own goals, I needed to revisit the Zettelkasten method.
But I didn't want to simply recreate another enhanced note-taking system that just pays homage to Niklas Luhmann's original system; I wanted a solution that adopted his techniques.
The difficulty with the Zettelkasten is that to make it work properly, we must at least obey two fundamental principles: atomic notes* and feste Stellordnung, which translates to “fixed position ordering.” We will discuss these terms often, but for the moment, it is enough to know that for Mind Dump to work, these two principles are essential.
A Zettelkasten is not a simple notebook, and it doesn't just write itself; it needs time, engagement, and understanding. Understanding these factors is crucial, as they create friction in note processing. My thinking was that with modern AI systems, it should be possible to ease the experience for people unfamiliar with the Zettelkasten method.
Although AI is baked into the system, I wanted the background to be accessible to users who wanted to build their own Zettelkasten outside of the AI tools.
So the Mind Dump Zettelkasten, as you see it today, is a hybrid AI/manual Zettelkasten background with a smooth UI and a friction-free note-capture interface.
Mind Dump Zettelkasten is still in development and advances daily as I work with my own Zettelkasten and adopt smoother approaches to everything.
My next post will focus on what you can expect your own Zettelkasten to give you.
*The concept of “atomicity” (strictly limiting one idea per note) was popularized by modern digital Zettelkasten proponents, such as Sönke Ahrens, rather than by Luhmann himself. In reality, Luhmann’s notes were often continuous streams of thought that carried over across multiple notecards to form chain-linked structures.
