Dim0

Your research is in the browser. Your notes are in Notion. Your diagrams are in Excalidraw. Your AI is in a chat box. Dim0 puts everything on one canvas. Dim0 is an open source, real-time collaborative thinking canvas where the AI agent reads your board, searches the web, and writes results directly as nodes, not in a chat box. No copy-paste, no tab switching. Key features: - Rich-text notes with markdown, math, code blocks, toggles, slash commands and sub-pages - Hand-drawn shapes and diagrams like Excalidraw - Mini-apps: describe a calculator, chart or quiz and the AI builds a real interactive React app right on the board - Live code execution inside canvas nodes - AI agent that reads your canvas context, searches the web, and places results directly as nodes - Real-time collaboration with live cursors, shared agents and no merge conflicts - Nested boards for organizing larger workspaces hierarchically - Presentation mode for framing and presenting directly from the canvas - 8 beautiful themes - MIT licensed, self-hostable, works with Claude, GPT, Gemini, Mistral, DeepSeek, Qwen, Kimi and GLM What is Dim0 for? Researchers and students who need to visualize complex information. Teams who want to think together on one board. Developers who think spatially. Anyone tired of switching between too many tools just to get one idea out of their head. How does it compare? Unlike Notion, Dim0 is spatial and canvas-first. Unlike Excalidraw, it has rich notes, code execution, mini-apps and a native AI agent. Unlike ChatGPT or Claude artifacts, the AI builds on a persistent board your whole team can use, so results don't disappear into a chat history. Is it open source? Yes. MIT licensed, fully self-hostable. github.com/vcmf/dim0
