CodeHerald
Most knowledge work is fragmented by design. You research in a browser, think in a whiteboard, write in a doc, ask AI in a chat - then spend 20 minutes stitching it all back together.
Dim0 keeps everything on one infinite canvas.
What makes it different: The AI agent isn't a sidebar. It reads what's already on your board before acting, searches the web, runs code, and writes results back directly as editable nodes - connected to your existing thinking.
On the same canvas you can: - Write rich notes with math and code - Generate mind maps, diagrams, and schemas from your notes - Run and execute code inside graph nodes - Upload documents and chat with them in context - Build and present directly from the board, no slides needed - Use 10+ AI models: OpenAI, Claude, Gemini, Mistral, DeepSeek and more
Open source. Self-hostable. No lock-in. The full codebase is public. Run it on your own infrastructure or use the cloud version at dim0.net.
Built for researchers, founders, and builders who think visually and move fast.
CodeHerald provides a new way to keep track of your code review queue, grouped by your next action needed.
If any of the above is true, CodeHerald will help you.
CodeHerald groups pull requests by next action: must review, needs an update, can be merged. It allows you to replace slack, emails, filters, and browser bookmarks with one single page that you can open at a glance and decide which PR to tackle next.

Dim0.net's answer
Dim0.net's answer
Most canvas tools add AI as an add-on that feels disconnected from your work. Dim0 is built the other way around - the canvas is the interface, and the AI agent is native to it. The agent reads your actual board before acting, searches the web, runs code, and writes results back as live editable nodes. Everything stays connected: notes, diagrams, code, documents, widgets, and presentations all live on the same infinite surface without a single context switch.
Dim0.net's answer
Notion is great for docs but flat. Miro is great for collaboration but not for thinking alone. ChatGPT is powerful but buries your work in chat threads. Dim0 is the only tool where the AI agent reads your existing board context and writes directly back onto it. It supports rich text, math, code execution, mind maps, document chat, and presentation mode - all in one place. It is also fully open source and self-hostable, so you are never locked in.
Dim0.net's answer
Researchers, founders, students, and builders who work through complex problems visually and feel frustrated by switching between too many tools. People who want one place to think, research, build, and present - without copy-pasting between a whiteboard, a doc, and an AI chat.
Dim0.net's answer
Built solo by a developer working a full-time job. The frustration was personal - existing whiteboards are built for team collaboration, not individual thinking. None of them support rich text, math, and code together. And even powerful AI tools like ChatGPT leave your work scattered across hundreds of chat threads. Dim0 started as the tool that never existed: a canvas that acts as a center hub where research, documents, code, diagrams, and AI all live together.
