Who it is for
People who think in boxes and arrows and want somewhere to draw them mid-conversation.
Overview
What B&A: Sketch does
B&A: Sketch is a whiteboard that opens inside the chat. The toolset is deliberately small: freehand strokes, basic shapes, lines, arrows, and text placed anywhere on the canvas.
It fits the kind of drawing that happens on a napkin. Rough diagrams, quick notes, a flow of boxes and arrows, or a scribble that captures an idea before it is fully worked out. The single suggested prompt is an invitation to start drawing, which reflects how open the surface is.
Kirill Dubovitskiy publishes this listing. A second app with the same name and description appears under a different developer. Nothing in the record covers saving, exporting, or sharing the canvas.
What stands out
It keeps the tool list short, closer to a whiteboard than to a design program.

Where B&A: Sketch is listed
B&A: Sketch is listed in the ChatGPT apps directory only. Kirill Dubovitskiy has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
