the creator is a former senior engineer at Microsoft (now retired), who worked on the math-editing features in software like Word. This editor give a elegant interaction

and I wonder if any one try to build a Math editor for web based on the native MathML element, not just imitate them with a batch Divs or Spans

yep and MathLive is another Math editor UX pioneer

this editor typing experience for math formula is so wonderful, I really like it

but I wonder if any plan to provide a minimal package, so that developers can integrate Corca into their product, something like MathLive or MathQuill
