Dim0 features
- Board-aware AI. The agent reads the entire board before acting, then searches, runs code and writes results as editable nodes.
- Infinite canvas with rich nodes. Add notes, shapes, math, code blocks, widgets, documents and nested boards on an endless surface.
- Mini-apps on the board. Describe a calculator, chart or quiz and Dim0 drops an interactive React app next to your notes.
- Real-time collaboration. Live cursors, presence and operational-transform syncing let multiple users edit simultaneously without merge conflicts.
- Presentation mode. Frame sections of the board and present directly from the canvas without exporting slides.
- Self-hostable & open source. MIT-licensed code can run on your own Postgres and vector DB, with full data ownership.
