BoostDraft is a software engineering company that develops IDE for documents. It was founded by MIT and Stanford grad students, developing an assisted document editor for documents. It is a new document editor that employs error checking, reference checking and auto-completion using both rule-based approach and NLP, like what coding editors/IDE (e.g. VSCode, Pycharm) do.
