Grammarly is a writing assistant that checks spelling, grammar, tone and clarity as you type. It works in your browser, in documents and in email. The free plan costs nothing and catches basic mistakes. The paid plan, Grammarly Pro, costs $12 per member per month when billed annually. This review looks at what each plan includes, what Pro adds, and who should pay for it.

Grammarly Review: What It Does

Grammarly reads what you write and suggests fixes in real time. It flags spelling errors, grammar mistakes and punctuation slips. It also shows the tone of your writing, so you can see if a message reads as friendly, formal or blunt. The tool works almost everywhere you type. Browser extensions cover Chrome, Edge and Safari. Desktop apps cover Windows and Mac. Mobile keyboards cover iPhone and Android. It also works inside Google Docs, Microsoft Word and Gmail. Grammarly says its service is trusted by over 40 million people and 50,000 organizations.

The free plan covers the basics well. It corrects spelling and grammar, shows tone, and gives you 100 generative AI prompts a month. Those prompts let you draft or rewrite short passages. For many casual writers, that is enough. The limits only start to bite when you write every day or need help with style rather than spelling.

Pro adds the features that change how the tool feels. It rewrites full sentences with one click. It adjusts tone, so a stiff email can become warm or a casual note can become formal. It offers fluency suggestions for people writing in English as a second language. It checks for accidental plagiarism and detects AI-generated text. It also raises the AI prompt allowance to 2,000 per member per month. Pro includes one style guide and one brand tone, plus team features for up to 149 seats.

Grammarly Free vs Pro: The Difference

The table below compares the two main plans. Enterprise sits above Pro for large organizations and is priced by quote.

The jump from Free to Pro is about depth, not breadth. Free fixes errors. Pro improves how your writing sounds. If you only need clean emails, Free is fine. If you write reports, essays or client work every day, Pro earns its keep.

Grammarly Pricing: What Each Plan Costs

Pro is one product sold at three prices. The only difference is how often you pay. Annual billing costs $144 per member per year, which works out to $12 a month. Quarterly billing costs $60 per member every three months, or $20 a month on average. Monthly billing costs $30 per member per month, with no commitment. Over a full year, monthly billing costs $360. That is two and a half times the annual price for the same features.

The billing term is the real pricing decision. If you need Pro for five months or more, annual billing wins. Monthly billing only makes sense for a short project. Quarterly billing sits in the middle at $240 a year.

Pro comes with a 7-day free trial. You pay nothing on day one. Grammarly sends an email reminder two days before the trial ends, so you can cancel before the first charge. Enterprise has no public price. It is sold through Superhuman Go, with unlimited AI prompts per member, single sign-on, data loss prevention, bring-your-own-key encryption and dedicated support. Contact sales for a quote.

One naming point causes confusion. Grammarly renamed its paid Premium plan to Pro. The plan you see at checkout is Pro. Premium still exists through the App Store and Google Play, with a smaller AI prompt allowance. If you read an older review that says Premium, it means the same paid tier as Pro today.

Who Grammarly Suits Best

Grammarly suits anyone who writes a lot in English and wants fewer errors in every app. Students get the most obvious value. Essays, applications and emails all benefit from clean grammar and a plagiarism check. Professionals who send client emails all day will notice the tone tools most. Non-native English writers get the most from fluency suggestions and full-sentence rewrites.

Small teams suit Pro well. One plan covers up to 149 seats at the same per-seat rate. The style guide and brand tone keep team writing consistent. Larger organizations should talk to sales about Enterprise, which adds admin controls, audit logs and custom security.

Grammarly suits casual writers less. If you write a few emails a week and rarely draft long documents, the free plan covers you. The same goes for confident writers who only need a safety net for typos. Pay only when a specific Pro feature solves a real problem for you.

Limits to Know Before You Pay

Grammarly has no lifetime plan and no one-time purchase. You rent it month by month or year by year. Refunds are issued only where required by law, according to Grammarly's refund policy. That makes the trial important. Test Pro for seven days before you commit to a year.

Pro also has caps worth knowing. You get one style guide and one brand tone. Teams that need several brand voices must move to Enterprise. The free plan's 100 AI prompts a month run out fast if you use the tool to draft text. Pro's 2,000 prompts are generous, but heavy users can still hit the ceiling.

Regional pricing varies. Grammarly lists US dollar prices by default. Euro, pound and rupee prices can appear at checkout depending on your region. Always confirm the price at checkout before you buy.

Bottom Line

Grammarly Free is a strong free tool. It catches real errors and works everywhere you type. Most casual writers never need to pay. Grammarly Pro is worth $12 a month on annual billing for people who write every day. The rewrites, tone tools and plagiarism check justify the price for students, professionals and non-native English writers. Pay monthly only for a short project. Otherwise, the $216 yearly gap between monthly and annual billing is money spent for nothing.
