Excalidraw drawing tool for hand drawn like charts and anything you can think of. Its open-source!

Описание: Excalidraw is an amazing tool to capture your ideas and save them onto your own computer. There are tons of libraries of shapes, icons, etc, you can import with a few mouse clicks. I find this tool very easy to use, intuitive and fun as you capture your ideas into a written form. A picture is worth a thousands words they say. And this gets you there for free.
