The short version
Grammarly is most useful at the final pass. It catches a missing article, a repeated word or a sentence that wandered off. Those are real time-savers. The trouble starts when every suggestion gets accepted simply because a colored underline is there.
What works
The basic correction loop is easy to understand. You write where you normally write, inspect a suggestion and decide whether it improves the sentence. That is particularly helpful for short messages that will be sent quickly and seen by someone else. Teams may appreciate shared style rules, though they need a clear reason to use them.
Where it gets fussy
A grammar checker does not know your audience or your intended joke. It may prefer a smoother sentence that says less. Browser extensions can also see text in places you type, so read the product’s privacy settings and decide where you want it enabled. For sensitive material, a local review process may be more appropriate.
Who should choose it
If small errors cost you time or confidence, the free entry point is a sensible place to start. If your main problem is structure, argument or reporting, this tool cannot do that editorial work for you. It can polish a weak paragraph without making it useful.
Our take
Accept corrections one by one. Keep unusual phrasing when it is doing a job. The goal is clean copy that still sounds like the person who wrote it.
