What if the whiteboard could read everything pinned to it and hand you back finished work, which is exactly the workspace Dim0 builds on your own server? One infinite board holds rich notes, hand-drawn and geometric shapes, images, documents, code sandboxes, and nested boards, all editable in place by a whole team at once with live cursors. The built-in agent sees the current board and your selected nodes, takes multi-step actions with its tools, and drops the answer back onto the canvas as a note, a mind map, or a working mini-app instead of burying it in a chat thread. Describe a tool in plain words and Dim0 generates a real interactive React app that lives on the board, reads the data sitting next to it, and can be opened, edited, and exported as code. Code nodes run in sandboxes, uploaded documents become searchable through retrieval, and presentation frames turn any board into a slideshow without exporting to a separate deck tool. You bring your own model keys for OpenAI, Anthropic, Gemini, Mistral, DeepSeek, or Qwen and switch providers whenever you like. Boards holding thousands of nodes still pan and zoom smoothly, and light, dark, and paper-and-ink themes restyle the whole surface.
