TL;DR

TL;DR

Thinking OS is a semantic “thinking infrastructure” that helps people capture ideas, turn them into structured concepts, and trace how those concepts evolve. Think of it like a note taker that traces how you think, define, and layer your ideas and definitions.


I led research, defined the core features, designed the interaction model and the user interface, and produced prototypes to gather user feedback and test my concept.

Origin

I’ve spent years watching my own notes scatter across tools Notion, Obsidian, Keep, Evernote, you name it. And when I tried to define my own ideas and concepts, I felt lost. Instead of clarity, I had chaos. I had no way to define how my ideas had evolved, how my concepts had changed with me. The tools that were supposed to empower thinking let me down, and in an AI-saturated environment, the cost was my own originality.

After mapping behaviours across archetypes, I synthesised and theme coded core tensions in how people capture, connect and rediscover ideas and concepts. These became the key insights and How Might We statements that guided my design decisions.

From the three archetypes, a pattern emerged: scattered capture, weak context, and no clear path from idea to synthesis.


Thinking OS is my answer to this gap. A semantic thinking infrastructure that sits in the background while you breeze through writing, accessing, and creating.

What Was Achieved

To me, Thinking OS has already begun to illustrate how tools for thought can evolve from simple note-taking apps into idea ecosystems.

Although Thinking OS was developed as a conceptual project, it has helped me understand the immense amount of groundwork that needs to be done before designing any software.


Due to the explorative nature of the space, this case study allowed me to experiment with new interaction models, test the limits of AI-assisted thinking, and refine my own systems-thinking approach.
