What is the Quick Sketch & Whiteboard?
Sometimes the fastest way to explain an idea, sketch a layout, or jot a quick diagram is to just draw it — without opening a heavyweight design app. This tool gives you a blank canvas with a pen, a set of colours and stroke widths, basic shapes (rectangle, circle, line, arrow), a text tool and an eraser, working with your mouse, trackpad or a touchscreen on tablets and phones.
There is no account, no cloud sync and no collaboration layer — it is a fast, local scratchpad. When you're done, export the whole canvas as a PNG image to paste into a document, a chat, or a slide, or clear it and start a new sketch.
