The Hidden Features of Grammarly Premium Most People Never Use

After three years of daily use, I am still occasionally finding features I did not know existed. Here are the ones most worth knowing about.

Most people use Grammarly as a spelling and grammar checker. It is much more than that, and its most useful features are buried where most users never look.

The Goals panel

The most underused feature in Grammarly. Click the target icon in any Grammarly editor and set your audience (general, expert, knowledgeable), formality level, and domain (academic, business, creative, casual). These settings dramatically change which suggestions Grammarly makes. A casual email gets very different suggestions from a client proposal. Most people never set these and wonder why suggestions feel wrong.

The synonym tool

Double-click any word in the Grammarly editor and get a contextual synonym panel. Better than a generic thesaurus because suggestions are ranked for this specific sentence, not just this word in the abstract.

The readability score

Scroll down in the Grammarly sidebar. The Flesch reading-ease score is there. Most people ignore it. If you write for a general audience and your score is consistently below 50, you have a clarity problem that grammar correction alone cannot fix.

The plagiarism checker

Available in Premium. Checks against billions of web pages. Useful for research-heavy writing — you want to know you have not accidentally reproduced phrasing from a source you read.

The weekly writing report

Grammarly sends a weekly email: words checked, accuracy score, top error types. I deleted these for a year. When I started reading them, I noticed I consistently made the same three or four errors. Addressing those deliberately improved my writing faster than anything else.

What this really means in practice

The practical question behind The Hidden Features of Grammarly Premium Most People Never Use is not whether AI writing tools sounds impressive in theory. It is whether the advice survives contact with an ordinary draft, a busy inbox, a deadline, or a reader who is not already convinced. That is the standard I use throughout this guide: if a recommendation does not make the next draft clearer, faster, or easier to trust, it does not deserve space on the page.

A useful writing tool should make your decisions sharper, not quieter. The simplest way to judge it is to keep the original draft open beside the edited version and ask what changed: did the tool remove mistakes, clarify the point, and preserve intent, or did it merely smooth the sentence until it sounded like every other article on the internet?

A simple way to apply it today

Start with one small test. Take a real piece of writing connected to this topic, not a perfect sample made for a tutorial. Read it once for meaning, once for structure, and once for friction. On the first pass, ask whether the point is worth making. On the second, ask whether the order helps the reader. On the third, look for the exact sentence where attention drops. That sentence is usually where the improvement begins.

For AI writing tools, the hidden cost is not the subscription. The hidden cost is unearned confidence. A sentence can sound polished while still being thin, vague, or factually weak. That is why every tool in this category needs a human review step: check the claim, check the example, check whether the paragraph actually helps the reader do something.

Mistakes to avoid

• Do not optimize the wrong thing. A cleaner sentence is not always a better argument. Improve clarity without sanding away evidence, personality, or useful specificity.
• Do not compare tools or techniques in the abstract. Test them on the kind of writing you actually produce, because a student essay, a client email, a blog post, and a newsletter all punish different weaknesses.
• Do not let speed become the whole goal. Faster writing is valuable only when the final message is still accurate, considerate, and recognizably yours.

My working checklist

• Does the opening tell the reader exactly what problem is being solved?
• Can a busy reader understand the recommendation by scanning the headings?
• Is there at least one concrete example, not only general advice?
• Would I still stand behind this paragraph if a reader made a decision from it?
• Is the final version sharper without becoming colder?

Final verdict

The best version of this advice is deliberately practical: use AI writing tools to reduce uncertainty, not to hide from judgment. The page should leave you with a clearer next action, not just a stronger opinion. If you remember only one thing from this article, remember this: the winning choice is the one that improves the real writing in front of you.
