Whiteboard

A vector whiteboard with pen, rectangle, ellipse, line, and arrow tools.

How to use it

Just ask for it in chat — the agent emits this widget and the shell renders it:

Example

The agent returns this A2UI component (inside the components array of a /chat response):

{
  "type": "whiteboard",
  "tools": [
    "pen",
    "rect",
    "ellipse",
    "line",
    "arrow"
  ]
}
