It started as a personal need. During my master’s, I felt I needed a note-taking tool that helped me explicitly visualize connections between different topics, something like a graph view. (I wasn’t aware of Obsidian at the time.)
Then I became a bit obsessed with creating something visual and compelling (like Miro) but also deep in content, behaving more like a knowledge base.
Miro is also very expensive (at least here in Brazil), so maybe NodeLand can become a more affordable alternative for individuals and small teams.
