A trackpad-first infinite canvas diagramming tool.
Most diagramming tools treat trackpads as second-class mice. HolyChart is built around trackpad gestures — including canvas rotation via two-finger twist, which virtually no other tool supports. Of course, it still works great with mouse as well and you can even create diagrams on mobile!
- Infinite canvas — pan, pinch-to-zoom, and twist-to-rotate with trackpad gestures
- Icon search — fuzzy-matches 150+ curated Material Design Icons instantly
- Boxes, text, icons — three element types with colors, labels, and resize handles
- Connections — draw arrows between elements with solid, dashed, or animated styles
- Multi-select — rubber-band selection, move groups together
- Diagram tabs — multiple diagrams per session, auto-saved to localStorage
- Export / Import — save diagrams as JSON, share and reload them
- Dark / light / system theme
