Open source AI canvas for visual thinking and research
4.8(6)16ProductivityDevelopmentNotes
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.
- Rich-text notes with markdown, math, 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 and builds results directly as nodes
- Nested boards for hierarchical organization
- Presentation mode — present directly from the canvas
- Semantic search across all nodes
- 12 beautiful themes
- MIT licensed, self-hostable, works with OpenAI, Claude, Gemini, Mistral, DeepSeek and more
- Researching and visualizing complex topics — ask AI, get a mind map on the board
- Learning difficult concepts visually with AI-generated explainers
- Technical documentation combining code, diagrams and rich notes
- Knowledge management and personal note-taking
- Building and presenting ideas without switching tools
- Self-hosting your own private thinking canvas

Hey Fazier! I'm Quang, solo dev from Paris. I built Dim0 because I was tired of switching between Notion, Excalidraw and ChatGPT just to think through one idea. Everything scattered, nothing connected. The part I'm most excited about: the AI agent doesn't answer in a chat box - it reads your canvas and writes results directly as nodes on your board. Your research becomes a living visual map you keep building on. It's MIT licensed and self-hostable - your data stays yours. Would love your honest feedback!
I think the idea is pretty cool

Thank you a lot! If ever you have a chance to test the product, please tell me your feedback!
Cool! What models are used?

Thank you! in Dim0 today you can select from a widge range of models from gpt models to claude to gemini to open-source top tier model like glm 4.7, qwen, deepseek.

The "AI writes results as nodes, not in a chat box" framing is the most interesting part of this. Chat interfaces force linear thinking — a canvas doesn't. Open source is a smart call too, this is exactly the kind of tool that benefits from community-built node types. What's the current limit on board size or node count?

Great question! The canvas performance is honestly one of the hardest problems to get right. Right now it handles 1000+ nodes per board and 200-300 visible at once smoothly. We use a hybrid Canvas2D + React Flow approach with some custom caching to make it work. Still room to improve but it holds up well for real research boards 🙂
Tech, AI, Bitcoin, RSI. My own opinions.
The canvas-first approach is compelling because research, notes, diagrams, and AI output usually live in separate tools. Having the AI read the board and write results directly as nodes feels much more useful than another linear chat interface. The open-source and self-hostable angle is also smart for people who care about data ownership. How are you thinking about collaboration features for teams?

Thank you so much! For your information, collaboration is absolutely next in the line. It took me sometimes to get the canvas correct. Next milestone will be collaboration
great idea, definitely something missing in the market

How do you handle persistent state across canvases? For long-running research projects I lose track of which threads I've already explored - does the AI agent remember context across sessions, or does each new canvas start fresh?

This tool is very good but What models are used?
