Templates & themes
Twenty-four starter templates
Blank, mind map, org chart, retrospective, flowchart, Kanban, SWOT and timeline to start, plus Gantt, Venn, user journey, fishbone, pyramid, flywheel, prioritization matrix, comparison table, ER / sequence / system-architecture diagrams, logo design, a live card, and mobile / laptop / slide-deck wireframes. Pick one, edit it, or start blank.
Twenty-seven preset themes
Basic, Forest, Ocean, Sunset, Rose, Midnight, Mono and a dozen more — plus multi-colour Rainbow, Pastel, Tropical, Autumn, and Jewel themes that tint each branch a different hue. One click recolours the canvas, every shape, and every arrow.
Build your own theme
Need your brand palette, a house style, or a notation that is not in the list? Build a custom theme, save it to your account, and reuse it across diagrams just like a built-in one. Edit it any time, and guests get them too.
Canvas & type
Set the canvas backdrop
Switch the canvas background between fourteen backdrops, from grid and lines to crosshatch, waves, isometric, and engineering, or none at all. Each theme and template picks a fitting default.
Eight fonts
Set the typeface per element or as a tab-wide default, from eight Google Fonts spanning sans, serif, slab, mono, and handwriting. New tabs inherit it, so a diagram reads consistently.
Organise in folders
File diagrams into nested folders in the explorer. Recent diagrams stay one click away; everything else lives where you put it.
Shapes & connectors
A shape for everything
Fourteen core shapes — flowchart blocks plus an actor, cloud, triangle, star, and speech bubble — a section frame that carries whatever you draw inside it, and six device frames (browser, monitor, laptop, phone, tablet, smartwatch). Click to drop one, or drag to draw it at the exact size you want, snapped to line up with its neighbours. A flowchart one minute, a screen the next.
Arrows that bend your way
Connect anything with straight, curved, or angled arrows. Drag the handle on a curve to reshape its bow, or on an elbow to move the bend. Set the thickness, choose the arrowhead shape, filled or hollow triangle, line, circle, or diamond, for UML-style connectors and size it, add a label, and pin an end to a shape so it follows when things move.
Style every border
Set border strength, switch between solid, dashed, and dotted, and round the corners as much or as little as the shape calls for.
