Grammarly vs ChatGPT for writing — which do you need?

One corrects text you wrote; the other produces text. If you are paying for both to do the same job, one of them is redundant — but often they are not doing the same job.

The short answer

Grammarly works inside whatever you are already typing in and corrects as you go; a general assistant produces and rewrites text in a separate window. The friction difference decides more than the capability difference. If you write in email and documents all day, the in-place correction is the thing you are paying for — and it is worth checking whether you use both for the same task.

The capability comparison misses the point

A general-purpose assistant can correct grammar, rewrite a paragraph and adjust tone. So can Grammarly. Comparing what each *can* do produces a near-tie and no decision.

The difference that matters in practice is where the tool is.

Grammarly sits inside what you are already typing in — email, documents, browser fields. No copying, no switching, no losing your place. That is the product.

A general assistant lives in its own window. You bring text to it and take text back. More capable for substantial rewriting, more friction for a sentence.

Which one fits which task

Correcting as you write, all day, in many places: the in-place tool wins on friction alone, and friction is what determines whether a tool gets used.

Drafting from nothing, or restructuring something substantial: the general assistant, clearly. Grammarly is not built for producing a first draft.

Writing in a second language: both help in different ways. The in-place tool catches errors continuously; the assistant explains why something is wrong, which is the part that improves you rather than just the text.

The overlap worth checking

Many people pay for both and use one. This is one of the more common redundant pairs in software subscriptions, and it is easy to miss because they were bought at different times for different reasons.

The check takes a minute: over the last two weeks, which one did you actually open? If a general assistant subscription is doing the correcting because it is already open all day, the specialised tool is paying for a habit you no longer have — and the reverse holds equally.

What free tiers cover now

Both have free tiers that have improved substantially, and several things that were paid features eighteen months ago are not any more.

Before renewing either, it is worth ten minutes to check what the free tier of your service does today. This category has moved faster than people update their assumptions about it, and a renewal is a decision even when it happens automatically.

On Prices

This page does not quote figures for either service, and that is deliberate rather than lazy.

Subscription prices change several times a year, differ between countries, and several of these providers bill in US dollars regardless of where you live — which adds an exchange rate and, depending on your card, a foreign transaction fee on top of the advertised number. A figure written into this page would be wrong for most readers within a year, and wrong for some of them on the day it was published.

Open both tariff pages. It takes a minute, and the number you find there is the one you will actually be charged. What this page gives you instead is the part that does not change that fast: what the two services are structurally for.

Where SubTracker Is the Wrong Tool for This

You want the cheaper one found for you. SubTracker does not compare tariffs or watch prices at providers it has no connection to. It records what you told it you pay and tells you before it renews.

You want somebody to cancel the loser. Rocket Money in the US, Volders or Aboalarm in German-speaking markets will do that. SubTracker shows you what to cancel and when; the cancelling is yours.

You have not decided yet and want a recommendation. This page gives you the structural difference so you can decide. It will not decide for you, because the right answer depends on how you use the thing, and that is information only you have.

Keeping Track of Whichever You Pick

The free plan records unlimited subscriptions with no card and no expiry, and tells you before a renewal lands. That is the part that makes rotating between services practical instead of theoretical: the reason people hold both is almost never preference, it is that the renewal date lives nowhere they look.

Renewal reminders and price-change alerts are Plus features. There is no trial — the free plan is not one, and it keeps working indefinitely.

Frequently asked questions

Can ChatGPT replace Grammarly?+

For capability, largely. For friction, no — Grammarly sits inside whatever you are typing in, while an assistant lives in its own window and needs you to bring text to it. If you write in email and documents all day, that difference decides it more than capability does.

Is it worth paying for both?+

Only if you use both for different tasks — one for in-place correction, the other for drafting and restructuring. Paying for both and using one is among the more common redundant pairs in software subscriptions, and it is easy to miss because they were bought at different times.

Which is better for writing in a second language?+

Both help differently. In-place correction catches errors continuously as you write; a general assistant explains why something is wrong, which improves you rather than just the text. If learning is part of the goal, the explanation is worth more.

Have the free tiers improved?+

Substantially. Several things that were paid features eighteen months ago are now free at both. This category has moved faster than people update their assumptions, so ten minutes checking what your free tier does today is worth spending before a renewal.
