Make diagrams that look hand-drawn, not corporate
Polished diagrams invite nitpicking; sketched ones invite ideas. Wobbleboard renders every shape with a deliberately imperfect, hand-drawn line so your diagrams say “work in progress — help me improve this.”
Why hand-drawn diagrams work
People are more willing to question and change something that looks unfinished. A crisp vector diagram feels final even when it is a first draft; a sketched one signals that feedback is welcome. That is why engineers, designers and product teams reach for sketchy diagrams in design docs and early reviews.
Control exactly how wobbly it gets
- Sloppiness: choose architect (clean), artist (natural) or cartoonist (very loose) per element.
- Fill styles: hachure, cross-hatch, zigzag or solid fills with your own colours.
- Edges and strokes: sharp or rounded corners, thin to extra-bold strokes, solid, dashed or dotted lines.
- Handwriting fonts: a hand-drawn typeface for labels, plus a normal and a code font when you need them.
From sketch to shareable
Drop diagrams into a README or a slide as SVG or PNG, or keep working together in a live session. Need structure? Try the flowchart maker workflow or sketch an architecture diagram.
Frequently asked questions
Can I turn the hand-drawn effect off?
Yes. Set an element’s sloppiness to “architect” for straight, clean lines, and use sharp edges and a normal font for a tidier look.
Does the hand-drawn style look the same everywhere?
Each element keeps its own random seed, so it renders identically every time you open the file, in exports and for collaborators.
Is the hand-drawn style just a filter?
No. Lines are generated procedurally as if drawn with a pen, so shapes stay editable and resizable rather than being flattened images.
