Grammarly Desktop Overview

Grammarly Desktop for Mac is a writing assistant that checks grammar, spelling, and tone directly inside whatever app you are already using, rather than requiring a separate browser tab. Once installed, it works across more than one million apps and programs, including Word, Pages, Mail, Slack, and most web browsers, showing suggestions right where you are typing. Beyond basic corrections, it can rewrite full sentences for clarity, detect the tone of your message before you send it, and generate first drafts of emails, reports, or outlines using generative AI. A quick toggle lets you turn Grammarly off in any specific app if you prefer privacy for that piece of writing. It suits students, professionals, and anyone who writes across many different apps and wants consistent suggestions without constantly copying text elsewhere.

Why Choose Grammarly Desktop for Mac?

A detail many reviews still get wrong is who actually owns Grammarly today. In late 2025, Grammarly became part of the Superhuman Platform, joining Superhuman Mail and Coda under one company umbrella. That shift matters if you are comparing account settings, billing, or support options, since some of it now runs through the broader Superhuman ecosystem rather than Grammarly alone.

The other change worth knowing about is pricing structure. The separate Grammarly Business plan has been retired and folded directly into Pro, which now supports teams of up to 149 members on its own, while larger organizations are pointed toward a custom priced Enterprise plan instead. Anyone comparing costs against an older review that still lists a standalone Business tier is looking at outdated numbers.

Supported macOS Versions

Grammarly Desktop for Mac requires macOS 10.15 or later and runs on both Apple Silicon and Intel Macs without any separate builds needed. Since suggestions rely on cloud based language processing, a steady internet connection is required for the app to function, even though it appears directly inside your local apps rather than a browser tab. No unusual hardware requirements apply beyond a reasonably current version of macOS.
