What Dim0 is
Dim0 is an open-source collaborative AI canvas where users can organize notes, mini-apps, and agents on an infinite board. Its agent can read the board, search the web, run code, and add results as editable nodes. Users can describe a calculator, chart, or quiz for Dim0 to generate as an interactive React app on the canvas. Collaboration features include live cursors, presence, shared agents, and synchronization with last-write-wins conflict handling. Notes use Markdown, and boards export without a proprietary format. Dim0 runs in a browser, with desktop builds documented for macOS, Linux, and Windows that can run locally and offline. In hosted cloud use, prompts, board context, and relevant uploads go to the selected model provider under that provider’s terms. Dim0 says cloud traffic uses TLS and stored data is encrypted at rest, but hosted cloud lacks customer-held keys and zero-knowledge end-to-end encryption. Plans include a Free option at no cost, Basic at €6.99 a month, and Plus at €11.99 a month.
