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 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 - Live code execution inside canvas nodes - HTML widgets — charts, visual explainers, interactive dashboards on the board - AI agent that reads your canvas context, searches the web, and places results directly as nodes - Nested boards for organizing larger workspaces hierarchically - Presentation mode — frame and present directly from the canvas - Semantic search across all your nodes and links - 12 beautiful themes - MIT licensed, self-hostable, works with OpenAI, Claude, Gemini, Mistral, DeepSeek and more What is Dim0 for? Researchers and students who need to visualize complex information. 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 and a native AI agent. Unlike ChatGPT, the AI builds on your board — results don't disappear into a chat history. Is it open source? Yes. MIT licensed, fully self-hostable. github.com/vcmf/dim0
