Recommendations to others considering Hemingway:
There's no reason not to use at least the browser version - it's free and helpful, and you can see if you want to grab the desktop version for $20. Set your expectations ahead of time; it won't do an exhaustive grammar search, so keep another solution for that in your pocket. Review collected by and hosted on G2.com.
What problems is Hemingway solving and how is that benefiting you?
It helps me communicate more clearly, tailor my writing to state my points, and get my words in order before sharing with faculty or other stakeholders. In my role, I need to be explicit and to the point, and I tend to over-write and miss the point. An editor like Hemingway helps me get out of my head and find the "statue" in the raw stone that I write out initially. Review collected by and hosted on G2.com.
