Hey HN,
I just built this as a sideproject with inspiration from http://textio.com after getting frustrated with the lack of feedback and haphazard advice for coverletters on a multitude of blogs. I built it using Flask, SpaCy, Textacy and NLTK with a bunch of heuristics that I took from writing blogs and form talking to experienced manager.
This is just an MVP so it isn't super fast and is missing a few nice-to-have features like HTTP.
