In their own words, as submitted to SaaSHub.


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...

As answered by people managing Dim0.net and Opalstack.
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.
Dim0.net's answer
