Frames and components
Auto layout and constraints keep frames in order. Components update every instance and keep your overrides. Smart guides snap to edges, centers and equal spacing.
Vectors and paint
A pen tool with editable points, plus union, subtract, intersect and exclude. Linear and radial gradients, image fills and rich text.
A whiteboard, too
Hand-drawn shapes, arrows that stay attached when you move things, sticky notes, smoothed ink and a laser pointer for walkthroughs.
Keyboard first
⌘K finds any command, tool, layer or page. Over 100 shortcuts, and ? lists them all.
Yours
Each project is a plain folder in Documents on your Mac. Changes save about a second after you make them. No account, no cloud.
In and out
Export PNG, SVG and vector PDF. Import Excalidraw scenes and libraries, and SVG files. Copy and paste works between projects and other apps.
