Dim0
Open-source collaborative AI canvas with board-aware agents, mini-apps, and real-time multiplayer.
Dim0 is a refreshingly honest open-source canvas for spatial thinkers who want AI that actually reads your work. The board-aware agent and mini-apps are genuinely useful, but v0.3 means rough edges and limited integrations—best for tinkerers and privacy-first teams, not enterprises. If you need deep third-party integrations or formal admin controls, Miro or Notion might serve you better; but if you value data control and a canvas that thinks, Dim0 is worth a try.

Skip Dim0 if you need deep third-party integrations (Slack, Notion, GitHub), strict enterprise access controls, or a traditional linear document editor; it's a canvas-first tool for tinkerers, not a heavy-duty platform.
Self-hosting requires your own Postgres and vector DB setup, which costs time and infrastructure.
Dim0's freemium model is friendly for solo thinkers and small teams; Free tier is genuinely usable for exploration. Basic at €6.99/month is cheaper than Miro or Notion's paid plans, but those offer more enterprise features and integrations. If you need advanced control, you'll pay more elsewhere.
In short
Dim0 — Open-source collaborative AI canvas with board-aware agents, mini-apps, and real-time multiplayer. Best for Researchers mapping literature and analyses, Developers prototyping with code on canvas, Writers structuring narratives with visuals. Free to start; paid plans from €6.99/mo.

About Dim0
Dim0 is an open-source, real-time collaborative AI canvas that merges notes, code, mini-apps, and AI agents onto a single infinite board. Instead of juggling five tabs, you think in one spatial workspace where an AI agent reads the entire canvas before acting—searching the web, running code, and dropping editable nodes right next to your notes. It's built for solo thinkers and teams who want context-aware assistance that starts from their actual work, not a blank chat thread. The board-aware agent, mini-app generation, and real-time collaboration are the core pillars, alongside rich notes, mind maps, and freehand sketching. Dim0 is MIT-licensed and self-hostable, giving you full data custody—no training on your content, no telemetry, no lock-in. The cloud version is free to start, with a Basic tier at €6.99/month that raises AI request limits. Currently at v0.3, it supports 8 AI models including Claude, GPT, Gemini, Mistral, DeepSeek, Qwen, Kimi, and ChatGLM, and offers eight light/dark themes. For those who want an alternative to Miro or Notion with real data control, Dim0 offers a unique, canvas-first approach.
Behind the Verdict
Dim0's core insight is that thinking happens in a spatial workspace, not in a linear document. The board-aware AI agent reads the entire canvas before it acts, which means it can synthesize context from your notes, code, and sketches rather than starting from a blank chat. Mini-apps are a standout—you can describe a calculator or a chart and get a real React widget on the board, editable and exportable. Real-time collaboration with operational transforms means two people can edit the same node without conflicts. Self-hosting with MIT license and zero telemetry is rare and valuable for privacy-conscious teams. However, the tool is early beta (v0.3), so features may be buggy. Integration with Slack, Notion, GitHub is absent, and self-hosting requires technical skill. For enterprises needing strict access controls, Dim0 falls short. Ultimately, Dim0 shines for researchers, developers, and privacy-first teams who want a canvas that thinks along with them.

Real-world workflow fit
Concrete scenarios for the personas Dim0 actually fits — and what changes day-one when you adopt it.
You're reviewing multiple PDFs and want to synthesize findings.
Outcome: Drop PDFs onto the canvas, ask the agent to summarize and extract key points, which appear as nodes next to your notes, ready to map.
You need to prototype a data pipeline with live code.
Outcome: Create code nodes that run in sandbox, visualize results with charts, and connect them to an architecture diagram you sketch—all on one board.
Your remote team is brainstorming product features.
Outcome: Use live cursors and shared agents; one person prompts, the agent builds on the canvas, and everyone sees updates in real time, refining together.
Use Cases
- Visualize research notes and automatically generate mind maps to see patterns.
- Prototype a data analysis pipeline with live code and chart nodes on one board.
- Collaborate with a remote team to brainstorm product features using real-time cursors.
- Create a mini-app like a quiz or calculator directly on the canvas using natural language.
- Synthesize information from multiple PDFs and web searches into a structured summary.
- Design a system architecture by connecting code snippets, diagrams, and AI-generated components.
- Sketch system diagrams and flows that the AI understands as context.
