Frequently asked questions
What is Dim0, exactly?
A thinking canvas where notes, docs, code, widgets, and AI agents live on one board together. Rich notes like Notion, freehand shapes like Excalidraw, agents that act on the board, all on the same surface.
Is Dim0 a Notion or Excalidraw alternative?
Yes. Dim0 is a Notion alternative and an Excalidraw alternative on one canvas, with a board-aware AI agent on top. Notion has rich notes but no canvas. Excalidraw has a canvas but no notes or AI. ChatGPT Canvas has AI but no spatial workspace. Dim0 has all three on one board, and the agent reads the surrounding context before it acts.
Is it free?
Yes, free to use during early access at app.dim0.net. The product is also open source: fork it, self-host it, bring your own model keys.
Is it open source?
Yes. Inspect it, fork it, self-host it. It’s all on GitHub.
Which AI models?
Claude, GPT, Gemini, Mistral, DeepSeek, Qwen, Kimi, GLM. Pick what you trust; switch as the landscape shifts. The workflow stays the same.
