Hemingway is an online proofreading app designed to make writing more readable. Hemingway judges the “grade level” of your text using the Automated Readability Index, a reliable algorithm in use for decades that gauges the lowest education level needed to understand your prose. Enter up to two paragraphs of text, and Hemingway's readability algorithm will highlight problem areas, color coded for hard to read, word choice alternatives, unnecessary adverbs, passive voice and more.
