I misread and thought this worked in the other direction. I’m used to working on a real whiteboard and I’m still to find a flow that works for me while nutting out architecture ideas with the team remotely. The best I’ve found so far is to scratch a little in Figma and then rework into real objects as we go. Anyone else have other tools for this?
Unfortunately the choice of font in the example you posted makes the diagram harder to read than it needs to be. Legibility has been sacrificed to achieve the hand-written look (a font that's less cursive in style might have been okay). Not a good trade-off IMO.
