Grammarly has a free plan and a paid plan, and the paid plan’s price depends heavily on how you pay. This guide explains what each plan costs, what you get, how student discounts work, which billing traps to avoid and whether Pro is worth it. Prices and offers change, so confirm them on Grammarly’s own pages.
Grammarly pricing at a glance
Free: $0, with core grammar, spelling and tone checks and about 100 AI prompts a month.
Pro: $12 a month billed annually ($144 a year), or $30 a month on monthly billing, with about 2,000 AI prompts a month, full rewrites, plagiarism and AI detection, and style guides.
Business (Superhuman suite): about $33 per member a month billed annually, or $40 monthly. It adds Superhuman Mail, which is email software, not better writing help.
Enterprise: custom pricing for large organisations.
Grammarly’s parent company renamed itself Superhuman in October 2025, but the writing product is still called Grammarly.
Is Grammarly Premium the same as Pro?
Mostly yes. Grammarly renamed its paid plan from Premium to Pro, so searches and older articles that say Premium are about the same plan. Check Grammarly’s plans page for the current names.
Free vs Pro
The biggest difference is the AI allowance, which jumps from about 100 prompts a month on Free to about 2,000 on Pro. Pro also adds full-sentence rewrites, plagiarism and AI detection, and style guides and brand tones. If you use fewer than about 25 AI prompts a month, Free probably covers you. Pro suits people who rewrite constantly, work in teams that need consistent style, or write in English as a second language and want a safety net in every app.
Billing: where people get caught
Annual vs monthly. Annual billing is $144 a year, and monthly billing is $360 a year, so paying monthly costs $216 more. The $12 figure is an average, because you pay $144 up front.
Auto-renewal. Subscriptions renew automatically at the standard price. Trustpilot reviewers report unexpected charges, renewals they didn’t expect and difficulty cancelling, so set a reminder before renewal and cancel in your account settings if you don’t want to continue.
Trials and refunds. Reviewers report being charged for a full year after a trial, and refunds can be hard to get, so read the terms before you pay.
Check at checkout. Sources show the monthly price in different ways, so confirm the amount before you enter payment details.
Grammarly student discount
This is the most contested part. A source dated early November 2026 says Grammarly offers eligible students and graduate students a discount of up to $72 on Pro, claimed through SheerID verification, and that Grammarly doesn’t issue coupon codes. Other sources from August 2026 say there is no simple self-serve student discount. Because the reports conflict, check grammarly.com/students directly.
Whatever you find, keep these points in mind:
- Many schools already have a licence. Grammarly for Education gives free access to enrolled students at some institutions, so ask your library or writing centre first.
- Discounts may apply to the first period only, and the plan then renews at the standard price.
- Coupon sites that promise 30% to 50% off may not reflect a real Grammarly offer.
Is there a free Grammarly Pro account?
Not legitimately. The free plan is real, some schools and employers provide Pro through a licence, and Grammarly sometimes offers trials. Accounts sold as “free Pro” or cracked versions break Grammarly’s terms and put your data and device at risk.
Is Grammarly Pro worth it?
Yes if you write daily, edit other people’s work, need plagiarism checks, or want style guides for a team.
Probably not if you write occasionally, or mainly want rewrites. The free plan covers basic checks, and a general assistant such as ChatGPT can reword text for free. For paraphrasing, QuillBot costs $8.33 a month billed annually. See Grammarly vs QuillBot.
