Grammarly is still the best writing assistant for most people who write at work. The Free plan covers spelling and grammar in 23 languages, and Pro adds 2,000 AI prompts, rewrites, tone controls and plagiarism checks for $12 per month on annual billing. Skip it if you will only pay monthly: $30 is steep next to QuillBot.
Grammarly is the best everyday writing assistant for most people: a usable free plan, a 2,000 prompt Pro plan at $12 per month on annual billing, plagiarism checks against 16 billion+ web pages, and the deepest security paperwork in the category. The tradeoff is the $30 monthly price if you will not commit to a year, and Trustpilot complaints about billing and intrusive upsells.

What it is
Grammarly is an AI writing assistant that runs where you type: a browser extension, Windows and Mac desktop apps, an iOS keyboard, and add ins for Word, Outlook and Google Docs. It underlines spelling and grammar issues, scores tone, rewrites sentences and paragraphs, and answers prompts like "make this shorter" or "draft a reply."
The company behind it has changed. Grammarly announced it would acquire the Superhuman email app on June 30, 2025, after earlier buying Coda, the docs and workspace tool. On November 5, 2025 it renamed the company Superhuman and introduced the Superhuman suite: Grammarly for writing, Superhuman Mail for email, Coda (now presented as Docs) and Superhuman Go, an AI assistant that works across apps. The App Store listing now shows the seller as Superhuman Platform Inc. In June 2026 Superhuman agreed to acquire GPTZero, the AI detection company, to fold its detection and plagiarism tools into Go.
For buyers, the practical effect is twofold. Grammarly the product keeps its name and its own pricing page, and Grammarly Enterprise is now sold "through Superhuman Go." There is also a second way to buy it: Superhuman's plans page bundles Grammarly into every Superhuman tier.
Pricing explained
Grammarly has three plans for individuals and teams. Prices below come from the plan data on grammarly.com/plans in October 2026.
| Plan | Price | AI prompts | Key inclusions |
|---|---|---|---|
| Free | $0 | 100 per month | Spelling, basic grammar, tone detection |
| Pro | $30 monthly, $60 quarterly, $144 yearly ($12 per month) | 2,000 per member per month | Rewrites, tone adjustment, plagiarism and AI detection, 1 style guide, 1 brand tone |
| Enterprise | Contact sales | Unlimited | Unlimited style guides and brand tones, BYOK, SCIM, DLP, audit logs |
The headline $12 is the annual rate. Pay monthly and the same plan costs $30, which is $360 a year against $144. The quarterly option at $60 ($20 per month) sits in between and is useful for a student who only needs it for one term.
Pro is a per seat plan. Grammarly's checkout data shows Pro prices apply from 1 to 149 seats, so a small team pays the same per person rate as a solo user. Team features like snippets, knowledge share, shared style guides and analytics are part of Pro. Security features like SAML SSO, custom roles, data loss prevention and domain controls are Enterprise only.
The Superhuman bundle. Superhuman's plans page lists Superhuman Pro at $15 per member per month billed monthly or $12 billed annually, and it includes Grammarly, Go and Docs. Superhuman Business at $40 monthly or $33 annually adds Superhuman Mail. The Superhuman page does not say whether its Grammarly limits match Grammarly Pro's 2,000 prompts, so check before you buy, but a $15 monthly price is half of Grammarly Pro's $30 monthly rate. See the full breakdown in Grammarly pricing.
There is a free Pro trial. Grammarly sends an email reminder 2 days before it ends, and the trial length is shown at checkout. Trustpilot complaints about surprise renewals mean you should set your own reminder too.
Key features
Grammar, spelling and clarity checks
Every plan checks spelling and basic grammar in 23 languages, including English (US and UK), Spanish, French, German, Portuguese, Italian, Dutch, Polish, Hindi, Korean, Chinese and Ukrainian. Advanced grammar, clarity, fluency and tone suggestions are limited to English, Spanish, French, German, Portuguese and Italian. Pro removes the cap on personalized suggestions and adds fluency help for non native English writers.
AI prompts and rewrites
The AI assistant drafts, rewrites and replies from a prompt. Free gets 100 prompts per month, Pro gets 2,000 per member, and Enterprise is unlimited. Pro also adds full sentence rewrites and tone adjustment, so you can turn a blunt email into a polite one with one click. Paragraph level rewrites work in the same 6 languages as advanced suggestions.
Plagiarism checker
Pro checks text against more than 16 billion web pages plus academic papers in ProQuest's databases, gives an originality score and highlights passages that need a citation. There is no published word cap. Citation formatting for APA, MLA and Chicago is built in.
AI detection and Authorship
Pro includes AI generated text detection. Authorship labels each part of a document by source: typed by you, pasted from a database, or generated by AI. That is useful for students who need to show their process. The GPTZero acquisition suggests detection will get more investment.
Style guides and brand tones
Pro includes 1 style guide and 1 brand tone, which apply house rules (product names, banned words, voice) to everyone on the account. Enterprise allows unlimited style guides and brand tones, which matters for companies with several brands or regions.
Translation
Inline translation covers 19 languages, including Japanese, Korean, Chinese and Turkish, so you can draft in one language and send in another without leaving the app.
What users say
On the App Store, the Grammarly AI Keyboard app holds 4.7 stars from 226,598 ratings. Trustpilot is harsher: 3.1 from 10,479 reviews, with 68% five star and 9% one star.
Recurring praise on Trustpilot: fast spelling fixes, better sentence structure, time saved on email, and support that processes refunds when asked. Recurring complaints: charges after a trial ended, pop ups and upsell prompts that interrupt writing, suggestions that sometimes change meaning, and recent changes that removed features users liked. Several reviewers say it is hard to reach a human in support.
The pattern is common in this category: the product scores well with active users, and the negative reviews cluster around billing. Read the trial terms and turn off auto renew if you only want a short trial.
Privacy and security
Grammarly publishes one of the strongest security records among writing tools. Its Trust Center lists SOC 2 Type 2, ISO 27001, ISO 27701, ISO 42001 (AI management), HIPAA and FedRAMP, plus annual third party penetration tests. It states that it does not sell content you upload and makes money from subscriptions, not ads.
On model training, Grammarly lets you opt out of using your content to train its models through the "Product Improvement and Training" setting. Enterprise adds bring your own key encryption, data loss prevention, confidential mode and audit log APIs. If you handle client or patient data, this is the reason to choose Grammarly over a cheaper rewriter.
Who it is for
- Professionals who write all day. The extension and desktop apps check email, Slack, docs and CRM notes without copy and paste.
- Students who need originality checks. The plagiarism checker and Authorship give a paper trail. The quarterly plan covers a term for $60.
- Non native English writers. Fluency suggestions, tone detection and translation into 19 languages help most here.
- Regulated teams. HIPAA, FedRAMP and SOC 2 make it easier to get approved by IT than most rivals.
Who should skip it
- Anyone who will only pay monthly. $30 per month buys QuillBot Premium, which costs $19.95 monthly, with money to spare. On annual billing QuillBot is $8.33.
- Novelists and long form writers. ProWritingAid's reports and chapter critiques are built for manuscripts, and its yearly plan is $10 per month.
- Marketing teams producing campaigns. Grammarly polishes; it does not plan or generate campaigns. Jasper or Copy.ai fit that job.
- People who mainly paraphrase. QuillBot's 9 paraphrase modes and custom modes do more for less.
Alternatives
- QuillBot: cheapest full toolkit at $8.33 per month on annual billing, with 25,000 plagiarism words a month.
- ProWritingAid: English only, but checks documents of any length and sells a $399 lifetime plan.
- Wordtune: unlimited rewrites for $9.99 per month, free unlimited grammar checks.
- Claude and ChatGPT: better for drafting from scratch, weaker as an always on checker.

Verdict
Grammarly earns its place as the default because it works everywhere you write, covers 23 languages on the free plan, and carries security certifications that most writing tools do not publish. On annual billing at $12 per month, Pro is fair value for 2,000 prompts, rewrites and plagiarism checks.
The weak points are price on monthly billing, a free plan that holds back plagiarism and AI detection, and a Trustpilot record full of billing complaints. Buy it annually, or compare the Superhuman Pro bundle at $15 monthly, and set a reminder before any trial ends.

Is Grammarly worth it in 2026?
For people who write email, documents and messages every day, Pro is worth it on annual billing at $12 per month. You get 2,000 AI prompts, full sentence rewrites, tone adjustment and plagiarism checks. On monthly billing at $30, it is harder to justify against QuillBot or ProWritingAid.
Is Grammarly free?
Yes. The Free plan checks spelling and basic grammar, shows the tone of your writing and includes 100 AI prompts per month. Plagiarism checks, AI detection, tone adjustment and full sentence rewrites need Pro.
How much is Grammarly Pro?
Grammarly Pro is $30 billed monthly, $60 billed every three months ($20 per month), or $144 billed annually ($12 per month), according to the plan data on grammarly.com/plans in October 2026. Enterprise is contact sales.
Is Grammarly owned by Superhuman now?
Grammarly the company renamed itself Superhuman on November 5, 2025, after buying the Superhuman email app (announced June 30, 2025) and Coda. Grammarly is still the name of the writing product, which now sits in the Superhuman suite next to Superhuman Mail, Go and Docs.
Is Grammarly safe to use for work documents?
Grammarly lists SOC 2 Type 2, ISO 27001, ISO 27701, ISO 42001, HIPAA and FedRAMP on its Trust Center and says it does not sell user content. You can opt out of model training in account settings. Enterprise adds BYOK encryption, data loss prevention and audit logs.
Does Grammarly have a plagiarism checker?
Yes, on Pro and Enterprise. It compares your text with more than 16 billion web pages and academic papers in ProQuest's databases and flags passages that need a citation. The Free plan does not include it.
Does Grammarly detect AI writing?
Pro includes AI generated text detection, and Grammarly's Authorship feature labels text by where it came from, such as typed, pasted or generated. In June 2026 Superhuman agreed to acquire GPTZero, an AI detection company, to build these features out.
Grammarly or QuillBot: which is better?
Grammarly is better as an always on checker inside email, docs and browsers, with stronger security and team controls. QuillBot is cheaper at $8.33 per month on annual billing and better for paraphrasing and summarizing. See our full Grammarly vs QuillBot comparison.
