If you’re considering Grammarly Pro, the free plan covers basic grammar and spelling — about 40% of what most daily writers actually need. Pro adds sentence rewriting, plagiarism detection against 16 billion web pages, and 2,000 AI prompts per month. Right now, a 20% affiliate discount drops the annual plan to $9.60/month.
No promo code needed. Click through the link on this page, choose the annual plan, and the discount applies automatically at checkout. A 7-day free trial is also available for new users — full Pro access, no payment required upfront.
This page covers what’s actually in each plan, how the pricing stacks up, and who should (and shouldn’t) pay for it.
- Grammarly is a grammar checker and AI writing assistant used by students, writers, and professionals daily
- The offer: 20% off Pro — $9.60/month on annual billing (normally $12/month); 7-day free trial for new users
- Who it’s for: Anyone writing significant email, reports, or content daily who wants real-time corrections and tone feedback
- Who should skip it: Occasional writers who send a few emails a week — the free plan covers that without paying anything
- FatSaver verified the 20% discount in May 2026. We re-check monthly.
What Grammarly Pro Offers (and What It Costs)
The free plan catches grammar and spelling mistakes. Useful — but also roughly what Google Docs does at no cost. The real gap between free and Pro shows up in three areas: sentence rewriting, plagiarism detection, and AI prompts.
Pro includes sentence-level rewrites (not just corrections), a plagiarism checker that runs against 16 billion web pages, tone detection that flags whether an email reads as aggressive or uncertain, and 2,000 AI writing prompts per month. The free plan gives you 100 AI prompts monthly — which sounds like enough until you’re editing a 10-page report on a deadline and hit the cap mid-session.
| Plan | Monthly Billing | Annual Billing | AI Prompts/mo |
|---|---|---|---|
| Free | $0 | $0 | 100 |
| Pro (standard) | $30/mo | $12/mo ($144/yr) | 2,000 |
| Pro via FatSaver | — | $9.60/mo ($115.20/yr) | 2,000 |
| Enterprise | Contact sales | Contact sales | Custom |
The quarterly plan at $20/month exists, but rarely makes financial sense. Annual billing saves 60% over monthly. Add the 20% affiliate discount on this page, and you’re at $9.60/month — the lowest price available through any standard channel.
How to Claim the Grammarly 20% Discount
No code needed. The discount applies automatically when you come through our link. Here’s the exact path:
On mobile, the order summary is collapsed by default. Tap “Show order summary” to expand it before checking the price breakdown at checkout.
How Much Can You Actually Save?
Standard annual billing: $144/year. Via the FatSaver link: $115.20/year. That’s $28.80 saved over 12 months — roughly three months of a Spotify subscription. The math isn’t dramatic, but it’s the lowest verified price available outside institutional or student programs.
I verified this in May 2026 by creating a new account and walking through checkout on the annual plan. The discounted price appeared at the payment confirmation screen without any additional steps. The 7-day trial countdown was visible in the account dashboard immediately after signup, with no waiting period.
One thing most Grammarly deal pages don’t mention: the 20% off applies to the annual rate only. Monthly billing won’t reflect the discount. If you need Grammarly for just one or two months, pay monthly and skip the annual commitment — the discount doesn’t help you there.
Where Grammarly Gets It Right
The integration coverage is wide and consistent. The Chrome extension works across Gmail, Google Docs, LinkedIn, Slack web, and most web-based text fields. The Microsoft Word add-in handles desktop writing. Between the two, corrections surface where you’re already typing — you don’t need to copy text into a separate app to use it.
Tone detection is more useful than it sounds. Grammarly flags when a specific sentence reads as passive or uncertain and shows you the exact phrase driving the signal. For anyone writing client-facing communications, catching a tonal misread before sending is worth something the free plan doesn’t give you.
The plagiarism checker is relevant for students and content writers specifically. It checks against 16 billion web pages and flags matched text with source attribution — comparable in scope to standalone plagiarism tools that charge separately.
The Honest Downsides
The free plan upsells aggressively. Pro feature prompts appear while editing — sometimes mid-correction, when a suggestion requires upgrading. It’s functional, but the friction is real if you’re trying to evaluate whether the free plan is sufficient. Users on Trustpilot consistently cite this as their primary frustration with the product.
Long documents hit performance issues. The browser extension slows noticeably on files above roughly 50,000 words, and suggestions can stop updating mid-document. For email, blog posts, and reports it handles well. For a full manuscript or technical spec of 80+ pages, reliability drops.
Cancellation works but requires navigating a retention flow first. You’ll receive a discount offer before the cancel completes. Not dishonest — but not a one-click process either.
Is Grammarly Legit?
Grammarly launched in 2009 and has been an operating company for 16+ years. It processes text for millions of users daily across education, enterprise, and individual accounts. That operating history puts it well outside the category of questionable SaaS products.
On Trustpilot, Grammarly holds a 4.5/5 score from 10,000+ reviews (source: Trustpilot). The most common complaint pattern centers on subscription cancellation friction and aggressive upsells in the free tier. The product works as described; the business model is pushy in specific places.
Payments process through Stripe. Refunds within 10 days of a renewal charge are available by contacting Grammarly support — that policy exists even though it isn’t visible on the standard pricing page.
Who Grammarly Is Best For
- High-volume email writers — professionals sending 20+ emails daily who want tone and clarity checks without manual re-reading
- Non-native English writers — sentence rewriting is particularly useful for writers whose first language isn’t English but who write for English-speaking audiences
- Students in writing-heavy programs — the plagiarism checker alone justifies the annual cost for anyone submitting academic work regularly
- Bloggers who run their own sites — if that’s you, our Hostinger coupon code pairs well for trimming the full content-creation bill
- Who should skip it: Occasional writers sending a few personal emails per week — the free plan is enough, and $9.60/month on tools you use twice a week doesn’t add up
Alternatives to Grammarly
- ProWritingAid — deeper style analysis, better for long-form fiction or technical writing; offers a one-time lifetime purchase that outperforms Grammarly’s value over a long subscription window
- Hemingway Editor — free web version focused on readability and passive voice; no AI features, no plagiarism check, excellent for clarity editing in isolation
- Google Docs built-in grammar check — free, catches obvious errors, no tone or style analysis; adequate for casual use

Frequently Asked Questions
Is Grammarly free to use?
Yes. Grammarly has a permanently free plan covering basic grammar, spelling, and punctuation corrections, plus 100 AI prompts per month. No payment details are required to sign up. The free plan doesn’t include sentence rewriting, plagiarism detection, or advanced tone suggestions — those are Pro features. You can use it indefinitely without upgrading.
How much does Grammarly Pro cost per month?
Grammarly Pro costs $30/month on monthly billing, $20/month on quarterly billing, or $12/month on annual billing ($144/year). Through the FatSaver affiliate link on this page, the annual plan drops to $9.60/month ($115.20/year) — a 20% discount applied automatically at checkout. No promo code required.
Does Grammarly offer a student discount?
Grammarly does not offer a dedicated verified student discount program through its main site. Some third-party platforms list student offers, but availability and terms change frequently. The 20% discount on this FatSaver page applies to all users regardless of student status and requires no verification — it’s the most reliable Grammarly deal currently available.
Is Grammarly worth paying for in 2026?
For daily writers, yes. At $9.60/month via the FatSaver link, Grammarly Pro covers sentence rewriting, tone detection, plagiarism checks against 16 billion web pages, and 2,000 AI prompts monthly. If you write significant email, reports, or content every day, the time saved on manual proofreading justifies the cost. For occasional writers, the free plan is sufficient.
How do I cancel Grammarly?
Go to grammarly.com/account/subscription, scroll to the Subscription section, and click Cancel Subscription. Grammarly will present a retention offer before completing the cancellation. Your Pro access continues through the end of the paid billing period. Refunds within 10 days of a renewal charge are available by contacting Grammarly support directly.
Does Grammarly detect AI-generated writing?
Yes. Grammarly Pro includes an AI detection tool that flags content likely generated by AI and shows a confidence percentage. It’s available in the web editor and desktop app. No AI detector is 100% accurate. Students should confirm their institution’s policy on AI content before using this tool for submission compliance.
Is Grammarly safe and private to use?
Grammarly transmits your text to its servers to generate suggestions. It uses TLS encryption in transit and AES-256 encryption at rest. Grammarly’s privacy policy states it does not sell personal data. Enterprise accounts include additional controls such as BYOK encryption. For highly confidential documents, review Grammarly’s full data handling policy before using.
The offer in plain terms: 20% off Grammarly Pro annual plan via our link — $9.60/month ($115.20/year) instead of $144. Seven-day free trial included for new users. No code needed. FatSaver verified this in May 2026 and re-checks it monthly.
If the trial doesn’t convince you, cancel before day 7 and nothing is charged. The free plan remains available after cancellation.
