Hemingway Editor

Hemingway Editor is a readability-focused writing tool available in the browser for free and as a desktop application for Windows and Mac as a one-time purchase. It analyses prose in real time, highlighting overly long or complex sentences in yellow and red, passive voice constructions in green, unnecessary adverbs in blue, and weak or hedging phrases in purple. A grade-level readability score using the Flesch-Kincaid scale shows the reading complexity of the entire piece. The desktop app works fully offline. Hemingway Editor is used by bloggers, content marketers, technical writers, and journalists who want to make their writing clearer, more direct, and easier for a general audience to read quickly.
