JEugene (YC S15) Detects Errors in Legal Documents, Saving Time and Money

I gave the tool a try on a document I'm drafting for review by our lawyer. It's pretty interesting and I can definitely see it saving some time. I'm curious though, aren't there any word processing applications built specifically for lawyers that solve this problem? It always amazes me how poor the functionality of Word for legal documents is.

Hi! Harry from jEugene here. jEugene's mission is to help lawyers work more and stress less. We would love to hear any feedbacks you may have. Note that jEugene is currently looking for NLP engineers interested in the legal industry. :)

perhaps i am missing something, but it looks like this just highlights two very common and easy to define types of error. how much practical value is there in this? Has this not been done before?
