Is Grammarly Premium worth it, now that it is called Pro?

Before answering whether is Grammarly Premium worth it, there is a fact that changes what you should be reading, and none of the guides on this question mention it.

That matters practically rather than pedantically. A review written against the old plan may be describing a feature split that has since moved, at a price that has since changed, for a company that has since been renamed — the enterprise tier on that same page is now described as “available through Superhuman Go”. So start from the current page rather than from anybody’s summary of it, including this one, and here is what it says.

Reading the six honestly. Two of them are about volume rather than capability. “Unlimited personalized suggestions” means the free tier shows you that corrections exist and withholds some of them, which is the oldest pattern in this business and the one that generates most upgrades. And the prompt allowance rises from one hundred a month to two thousand, which is a real difference only if you are using it as a writing generator rather than as a checker.

And there is a place where that dividing line stops being a matter of taste. If the writing is going to be assessed, the paid tier’s headline features are the ones the rules name.

Three are about rewriting rather than correcting: rewriting full sentences, adjusting tone, and “write fluently in English”. This is the genuine dividing line between the tiers, and it is worth naming plainly. The free tier fixes what is wrong. The paid tier changes what is right into something different. Whether that is worth paying for depends entirely on whether you want your sentences altered — and there is a real cost on the other side of it, which is that heavy suggestion-taking flattens a voice into the same competent, frictionless register everybody else’s tool produces.

The sixth is the one this section has the most to say about: “detect plagiarism and AI generated text”. Read that as a feature you are being sold, not as a service you are receiving. A plagiarism check compares your words against an index and reports overlap, including the quotations you cited correctly; an AI writing score is a probability presented as a percentage. Both are useful and neither is a verdict, and the guides below set out exactly what each can and cannot support. If those two features are the reason you are considering paying, read them first — it is the single most expensive misunderstanding in this section.

Who the answer is usually different for. If you write in English as a second language, the rewriting features address the thing you actually want help with, and the free tier addresses much less of it. That is the group for whom the gap between the tiers is widest, and it is worth saying because those reviews rarely separate it out.

If you write professionally and your work is edited by somebody else, the paid rewriting is mostly redundant — you already have the thing it approximates. If you write occasionally, the free tier covers the case almost entirely. And if you are a student, check your institution’s policy on writing assistance before paying for a tool that rewrites sentences, because the question of whether you may use it is separate from the question of whether it is any good, and it is the one with consequences.

Why this guide does not end with a verdict. Because we have not run the test yet. Deciding whether a paid writing tool earns its subscription — and, if it does not, cancelling it from the phone rather than from inside the app — requires putting the same texts through the free and paid tiers over weeks, keeping what each one caught and what each one changed, and publishing the results — and until that exists, a verdict here would be somebody’s impression dressed as a finding. Every page above this one in the search results has a verdict. Several of them also have an affiliate link to the thing they are recommending, which is worth knowing while you read the verdict.

What this guide gives you instead is the current feature split from the company’s own table, the current plan name, the note that the price is regional, and the six differences stated plainly enough to check against your own month. That is enough to decide, and it is more than most of the pages ranking above it can honestly claim.

One practical note that costs nothing. The paid tier is offered with a trial and the pricing page states “Email reminder 2 days before trial ends” — so the low-risk version of this decision is to use the trial deliberately on real work, not on a test sentence, and to answer the question with your own documents rather than with anybody’s review. Set your own reminder as well as theirs.

Not covered here. It will not tell you to buy it. We have not run the comparison that would justify saying so, and a verdict without that test is an opinion wearing a lab coat.

It will not tell you to avoid it either. The feature list above is real, and for some readers — particularly anybody writing in a second language — the gap between the tiers is genuinely large.

And it will not carry an affiliate link, which on this exact search is the reason most of the pages above it exist. What holds instead is simple: the plan names and the trial terms are quoted from the company’s own pricing page, read on the date this page names.
