What is Dim0?

Dim0 is an open-source, real-time collaborative AI canvas that combines Notion-grade notes, an infinite whiteboard, and a board-aware AI agent on a single surface. Every kind of node — code, widgets, math, images, hand-drawn shapes, docs, and nested boards — lives on the canvas and can be read by the AI. It is positioned as a self-hostable, privacy-first alternative to tools like Miro, FigJam, Notion, and Excalidraw.

How to use Dim0?

Start free on the canvas with nothing to set up. Create notes, shapes, code, and other nodes on the infinite board, then prompt the board-aware agent to search, run code, or generate interactive React mini-apps directly on the canvas. Invite teammates for real-time collaboration with live cursors and shared agents, or self-host the MIT-licensed codebase with your own Postgres, vector DB, and model keys.
