Our Grammarly review
If you need email polish, Grammarly is one of the safest picks in AI productivity — with the caveat that suggestions can flatten your voice.
We score Grammarly 4.5 out of 5 — excellent ease of use, solid performance and strong value for money.
What Grammarly is
Grammarly is Grammarly's AI productivity product, launched in 2009. Writing assistant that corrects, rewrites and adapts tone everywhere you type, with generative drafting built in.
It is aimed at beginner users — the learning curve is very gentle. Day one you would use it for email polish, reports and student essays. It runs on Web, Chrome, Desktop, iOS and Android, including a mobile app, and there is an API if you want it inside your own systems.
Where it shines
What you are really paying for here: works across browser, desktop and mobile and strong free tier. The feature set behind that is grammar and clarity, tone rewrites, generative drafting and works in any app.
We rate performance 4.3/5 and answer accuracy around 90% for the tasks in this category, which is why it holds up for email polish and reports.
Where it falls short
It is not without cost or compromise: suggestions can flatten your voice.
Nothing here needs training, so the risk is not difficulty — it is paying for capability you never use.
Pricing and value for money
Pricing is Free · Pro $12/mo · Business $15/user/mo. At $12 a month that is $144 a year per person, in line with the rest of the category (the category median is about $10). A free tier exists, so you can test it properly before paying.
If budget is the constraint, Notion AI at $10/mo does much of the same work. Our cost calculator will show what adding Grammarly does to your monthly stack before you commit.
Who should use Grammarly
