I started using Hemingway from it's first iteration. First for my uni assignments and since then I've used it for almost everything. Slide decks, presentations, social posts, campaign copy, you name it. I even used it for this review! haha
Simple, unambiguous, clutter-free writing made easy for anyone. Hemingway is a godsend for people like me that, completely unintentionally, wax poetic about stuff that can be said in a few words.
