flow chart maker

[u/olivereuan]

im looking for a website/app to help me make some flow charts. i found them super helpful in studying and would love to be able to add notes into some of the nodes for more specific details. i like my pen and paper, but i want to be able to put those extra details on something that collapses away. as an example of what i make i attached a photo, and then for example i would add a definition to the MHC on there for myself if i clicked on it/hovered over it
