A graph-based notebook web-app


I and my teammates developed Potion(Po for POSTECH + Notion) at the university hackathon competition.

The project was based on my idea that we need some kind of note app that enables users to build a personal knowledge graph and lets them visualize their notes at a glance.

Although the quality of the project is not that impressive as the prototype was made less in than a day, it is surprising that the idea became realized by other guys after a few years (such as Roam Research and Obsidian. I still believe that these apps will be the next generation note taking apps, as a system for personal knowledge management.

Still, these apps need way more improvement compared to apps like Notion or Evernote.


The source code is uploaded into my github, where it includes a test demo case when a student studying physics is studying with Potion.
