What does Dim0 help with?

Why I built this

I got tired of switching between Notion, Excalidraw, and ChatGPT just to think through one idea. Every tool does one thing well but none of them share a surface. Your thinking ends up scattered across tabs, chats, and screenshots.

Dim0 is my attempt at a "cartographie de connaissances" - a single canvas where research, notes, diagrams, code, and AI live together. Built solo, open source, and genuinely useful for anyone who thinks visually.
