Excalidraw | Course KB

A hand-drawn-style whiteboard — the course's thinking surface for node anatomy and workflow mind maps.

Pick this when

You want to explain a structure fast and the sketchy look signals 'this is a draft, argue with it'.

What makes it different

Deliberately informal styling that invites correction rather than approval

Boards export as JSON, so a diagram becomes a shareable, editable artifact

Free, instant, no account needed to start

What it does

Draws diagrams and mind maps collaboratively in the browser

Exports boards as JSON for sharing (the BC3/BC4 boards shipped in the resource pack)

What it does not do

Common wrong expectations

Doesn't produce polished final diagrams — that's not what it's for

Where it sits in a stack

The explain-it-live seat during teaching or design discussion.

Our status · watch

The KB's figures are hand-authored SVG in the house palette, which serves the same purpose with more polish.

For your projects

The exported-JSON habit is worth copying: the pipeline's figures are already versioned text, which is why they diff cleanly.
