I love Excalidraw. It is not as powerful as draw.io or something, but its small set of tools and default colors are perfect for me when I need to sketch a diagram without needing to think to much about the format instead of the content. The draft style of Excalidraw helps me to express the idea of informality, like I would do if was writing in a whiteboard explaining something instead of writing a formal document to be published.
