Is there a one-time payment for Grammarly?

People search for a one-time Grammarly payment for a simple reason: they have one document — a cover letter, an application, a dissertation chapter — and they do not want a plan that renews. Grammarly's paid Pro plan is sold as a subscription, priced per month on its own plans page, so the honest answer is no. Here is what that means if you write occasionally, how to use a subscription for one document without being surprised by the renewal, and what a one-time grammar check looks like instead.

The short answer: a subscription, not a purchase

Grammarly's plans page lists a Free plan, a paid Pro plan priced per month, and Enterprise for organisations. Pro is a subscription that keeps billing until you cancel; the page offers no way to buy a single document or a lifetime licence. If someone offers a one-time lifetime Grammarly account elsewhere, treat it with suspicion — it is not something Grammarly sells.

That model makes sense for people who write all day. It makes less sense for someone with one important document every month or two, who pays for the weeks in between too.

If you take the subscription for one document

It can still be the right call, especially if the free trial or the shortest billing period covers the job. Two habits stop it costing more than you meant:

- Set a reminder for the day before it renews, the moment you subscribe.
- Cancel as soon as the document is done, and check what the cancellation screen says about access until the end of the period you paid for.

The common regret is not the first payment but the renewal months later, for a document long since sent.

What a one-time grammar check looks like

polishdoc is built for the occasional document. You paste your text and get a free sample on your own words first, with no account. If you like the edit, one payment polishes the whole document — grammar, spelling, punctuation and clarity — in the language you wrote it in. There is no plan, no renewal date and nothing to cancel. The one payment covers several full-length documents, so the next cover letter is already paid for.

It edits; it does not write. It will not add facts, achievements or paragraphs you did not write, and it does not keep your text after the request.

Free options first, if the text is short

For a short email or a single paragraph, a free grammar checker is often enough: the free tiers of the large tools catch spelling and basic grammar, and your word processor's built-in checker catches more than it used to. Pay for help when the document matters — something going to an employer, a university or a client — and when the problems are about clarity and phrasing rather than typos.
