Dim0

Dim0 is an open-source, real-time collaborative AI canvas that brings together notes, code, mini-apps, and AI agents on a single infinite board. It solves the problem of scattered thinking across multiple tabs and tools. The board-aware agent reads the entire canvas context before acting—searching, synthesizing, running code—and drops results as editable nodes. Users can create sticky notes, write and run sandboxed code, generate charts, upload documents, and even spin up interactive mini-apps (like calculators or visualizers) using natural language prompts. Designed for solo work or team collaboration, Dim0 features live cursors, shared agents, and conflict-free editing. It is privacy-first, MIT-licensed, and self-hostable, offering a strong alternative to proprietary tools like Miro or Notion for users who want full control over their data. Key features include an infinite canvas with nested boards, a board-aware AI agent, sandboxed code execution, mini-app generation (real React widgets), real-time multiplayer with live cursors, mind map generation from notes (Mapify), support for 8 AI models (Claude, GPT, Gemini, Mistral, DeepSeek, Qwen, Kimi, ChatGLM), document upload, math and chart rendering, rich notes (tags, math, toggles, sub-pages, code), freehand drawing (Excalidraw-style), and eight themes. Self-hosting gives full data custody. Dim0 is aimed at knowledge workers, researchers, developers, and teams who need a spatial, AI-augmented thinking tool. Unlike Miro or Notion, it is open-source, privacy-respecting, and built canvas-first with an agent that reads context. It's still early (v0.3) but offers a unique approach for those who value flexibility over polished integrations.
