Hemingway Editor

Readability highlights

Sentences more complex than the target readability score are highlighted in yellow, and the hardest ones in red, so they can be split or simplified.

Weak-writing checks

Flags adverbs and other weakeners, passive voice and words that have a simpler alternative, and each type of highlight can be hidden.

AI sentence rewrites

Editor Plus rewrites a highlighted sentence, a paragraph or a whole document on request. Each sentence rewritten uses one AI sentence credit.

Tone and style changes

Editor Plus can shorten a passage, add detail or make it more confident, friendly, casual, formal or persuasive, and it accepts custom instructions.

Document review and feedback

Editor Plus comments on a draft as a reviewer would, for example on tone and repeated words. Reviews are unlimited on every paid plan.

Desktop app

Hemingway Editor 3 for Mac and PC imports Word files, exports to text, PDF, Word, HTML or Markdown, and can save a PDF with the highlights intact.

LanguageTool

Grammar, spelling and style checks

Checks grammar, punctuation, spelling, casing and style. Premium adds more than 20,000 extra checks for English, German, French, Spanish, Dutch, Polish and Portuguese.

AI paraphrasing

Rephrases a sentence to be more formal, more fluid or shorter. Basic accounts get 3 rephrasings a day and Premium removes the limit.

Long-text checking

Premium checks up to 150,000 characters per text field, against 2,000 on the Basic plan.

Style guide and dictionaries

Custom rules enforce consistent wording. Teams share a style guide and a dictionary of approved terms, with admins deciding who can add to them.

Add-ons and apps

Browser add-ons for Chrome, Edge, Firefox, Safari and Opera, plugins for Google Docs, Word, Apple Pages and LibreOffice, email add-ons, and apps for Windows, macOS and iOS.

Open-source core and API

The core checker is open source, with code on GitHub, and users can set up their own LanguageTool server. A hosted Proofreading API accepts up to 60,000 characters per request.
