Grammarly
An AI writing assistant that fixes grammar, tone, and clarity across your apps — and now drafts and rewrites on request.
Visit official site →What is Grammarly?
It works across roughly 500,000 apps and websites according to the company, which is the real reason to use it: corrections come to you in Gmail, Slack, Word, and LinkedIn instead of asking you to paste text somewhere else. Grammarly reported more than 40 million daily users as of mid-2025. Since the October 2025 rebrand the parent company is called Superhuman, though the writing product is unchanged. If English is your second language or you write all day, the free tier alone is worth installing.
Three things Grammarly does best
-
Fixes your writing wherever you already type
The browser extension and desktop app place suggestions directly in Gmail, Google Docs, Word, Slack, LinkedIn, and most web text fields, so nothing has to be copied into a separate window. Basic grammar, spelling, and punctuation corrections are free with no ads.
-
Adjusts tone before you send something wrong
Pro flags when a message reads as blunt, hesitant, or overly formal and rewrites it in one click, and includes roughly 2,000 generative AI prompts a month. Teams can set a brand voice and style guide so everyone's writing lands consistently.
-
Shows whether text looks copied or AI-written
Pro includes a plagiarism checker against web and academic sources plus an AI detector that estimates how much of a passage reads as machine-written. Both are Pro-only, and on desktop they currently run inside Microsoft Word rather than everywhere else Grammarly works.
Grammarly has a free plan, so the fastest way to judge it is to try it on one real task.
