Adam and Ben Long have created an app that analyzes text with the goal to help make your writing bold and clear like that or Ernest Hemingway.
It’s called Hemingway. “Hemingway highlights long, complex sentences and common errors; if you see a yellow highlight, shorten the sentence or split it,” explains the site. “If you see a red highlight, your sentence is so dense and complicated that your readers will get lost trying to follow its meandering, splitting logic — try editing this sentence to remove the red.”
The New Yorker has more about how it works:
Hemingway uses a formula to judge the “reading level” of a particular selection of writing, which the Longs said is “a measure of how complex the sentence structure is and how big the words you’re using are.” It scored my first paragraph as Grade 14. The app suggests that anything under Grade 10 is a sign of “bold, clear writing.”
