Grammarly is an AI-powered writing assistant that works via browser extension, desktop app, and mobile keyboard. Goes beyond grammar and spelling to suggest tone adjustments, full-sentence rewrites, clarity improvements, and vocabulary enhancements. Pro plan includes plagiarism detection, brand tones, style guides, and 2,000 AI prompts per month. Works inside Gmail, Slack, Google Docs, Word, and most web apps.
Content creators and marketers who write daily, teams needing consistent brand voice across communications, non-native English speakers polishing professional writing, customer support teams maintaining quality standards
Grammarly recently consolidated Premium and Business into a single Pro plan at the old Premium price point. The browser extension is where most value comes from — it follows you everywhere you write. AI suggestions are not always right and can flatten distinctive voice. Best ROI for teams doing high-volume client communication.
Creative writers who find suggestions strip personality, technical writing with domain-specific jargon Grammarly does not recognize, businesses needing full content generation (it assists writing, not replaces it)
Reviews from businesses like yours — matched by size and type. Available once you create a profile.

I don't find that it (defaultly) corrects too far into the ai slop territory. It's mostly just making sure your sentence is correct.

They give you a long list of suggestions, and unless you write a corporate press release half of them are best ignored. The skill is in choosing which half to ignore.

I think many people have used these advanced spellcheckers for years before Chatgpt et al came on the scene.

I was very happy with Grammarly swapping my dashes to em dashes. But now everyone associates em dashes with AI, I can no longer enjoy that luxury.

I use Grammarly because it helps fix speech recognition errors. One of the challenges of speech recognition use is that it is a bit difficult at times to construct grammatically correct sentences in your head.

I use Grammarly for finding outright mistakes (spelling and the like, or a misplaced comma or something), but I don't listen to any of the suggestions for writing. It feels mechanical and really homogeneous.

I didn't renew this year because I have multiple AI subscriptions, and Grammarly was the least critical of them.

the main advantage of Grammarly was the user experience of having mistakes and suggestions inline and just a click away while editing, as well as the quality of the suggestions.

I always thought of Grammarly as a premium entry into that segment for proper professional writing. Shame it’s going the way of slop.

I've been a long time user of Grammarly. I have used it for most of my books. I've used it as an example of good ux for AI.
