Dim0

Dim0 is an open source, real time collaborative AI canvas that places notes, small interactive apps and an AI agent on one infinite board. Instead of moving between a notes tool, a whiteboard and a chat assistant, users keep everything in one spatial workspace, and the agent reads the whole board before it acts. It can search the web, run code and write its results back onto the canvas as editable nodes. It is aimed at individuals and teams who think visually and want AI that works with their existing material rather than a blank chat window. Mini apps let a user describe a calculator, chart or quiz and receive a working React component on the board. Rich notes support tags, math, toggles, sub pages and code; Mapify turns notes into mind maps, schemas or diagrams; nested boards open like folders for large projects; and presentation mode turns framed areas into slides. Collaboration includes live cursors, shared agents and conflict free syncing, and the product offers a choice of eight AI models. Pricing is published in euros. Free costs nothing and includes 50 AI requests a day. Basic costs €6.99 per month with 150 AI requests a day. Plus costs €11.99 per month and removes the AI request limit. The project is released under the MIT License and can be self hosted. Its canvas rendering engine, canvas harness, is also published as a separate open source project.
