When working remotely as a contractor I made a tiny whiteboard - https://onthesamepage.online/about https://onthesamepage.online/about I still use it for quick notes and spontaneous collaboration, since there are no accounts or registrations - it takes a few seconds to onboard a person. Also I was surprised that German school are using it (it’s heavily focused on privacy and requires no personal information). Sorry if it sounds like shameless promotion, but for me it was hard to find an alternative, something as simple as notepad.cc in its days, but for doodling.
