About Dim0

Dim0 is an open-source, real-time collaborative canvas for people who think spatially and want AI in the same workspace. It brings notes, interactive mini-apps, code, documents and a board-aware AI agent onto one infinite board, so teams and solo users do not have to copy results between a doc tool, a whiteboard and a chat window.

What sets it apart is that the agent reads the surrounding board before it acts, then writes its answers back as editable nodes rather than leaving them in a chat thread. Mini-apps are generated as real React apps placed next to the notes they use, and boards can be presented as slides straight from the canvas. Users can choose among several model providers.

The codebase is MIT-licensed and can be self-hosted with local Postgres and your own model keys. Boards export as plain Markdown and the site states that content is not used for training and that no behavioral telemetry is collected. A free tier and paid plans are offered on the cloud version.
