I like to write lean canvases as idea notes. It is good to organize information about a new product or new something.
I know the best way to make the lean canvas is hand-writing with A3 paper. However, sometimes I want it on digital tools.
Besides, I love markdown and crafting something by writing markdown, such as the "marp".
(marp is markdown presentation maker).
