Is Grammarly legit?
LegitGrammarly checks out as a real business, the writing assistant that flags grammar and tone as you type, but its paid plans need a close eye. They renew on their own at the standard rate, and the billing policy only mentions refunds for billing errors, so a forgotten yearly renewal is hard to claw back.
What we checked
- Writing assistant since 2009
- Company renamed Superhuman in 2025
- Based in San Francisco, CA
- Ratings on other review websites: 3/5
Watch out for
- A plan that renewed automatically at the standard rate, using the card already on file.
- A Grammarly document-share email from a sender you do not know, with a phone number or link inside.
- An email that copies Grammarly's look but comes from an address outside its own domains.
Grammarly Pro renewed when you meant to stop?
We help you write it, it gets its own public page, and you can have it sent to Grammarly as a formal letter.

How do I file a complaint about Grammarly?
Do you have a dispute or a bad customer experience with Grammarly? Report it through our website to maximize the chance of getting it resolved.
We help you write an effective complaint in minutes. Our AI models are trained on thousands of effective complaint letters. Then we push it through emails, social media, paper complaint letters and other tools at our disposal. And you are not alone: our helpful community is there for advice.
How do I contact Grammarly customer service?
Grammarly has no customer service phone number: its help center says it does not provide phone support. Start with the support chatbot in the Grammarly help center, linked in the contact details above, which can pass you on to a ticket through the request page, or write to support@grammarly.com. Business and Education customers get priority support. Give the email address on your account, your plan, and the date and amount of any charge in question.
Charge or account problem to put on record? Start your complaint here at the same time, and we push it out to Grammarly by email, social media and printed letters.
How do I cancel Grammarly and get a refund?
To cancel Grammarly Pro, turn off the renewal in the subscription settings of your Grammarly account before the next billing date, or in the App Store or Google Play if you subscribed through a mobile app. Canceling stops the next renewal but does not by itself refund a charge already taken. Keep the confirmation email and a screenshot of the subscription page.
For money back on a renewal, ask through the Grammarly help center or support@grammarly.com, quoting the invoice date and amount and explaining why a refund is due, for example a renewal you did not use. Whether a refund is given depends on Grammarly's terms and the law where you live.
Renewal taken for a plan you no longer use? Bring it through our complaint process: our trained AI opens a case for you and keeps coaching you on what to reply and when to push again.
Is Grammarly now Superhuman?
The company behind Grammarly is now called Superhuman: in October 2025 Grammarly, Inc. renamed itself, and its legal name is Superhuman Platform Inc., while Grammarly stays the name of the writing assistant. Grammarly is now part of the Superhuman Suite, alongside Superhuman Go, Mail and Docs, after the company bought Coda and Superhuman Mail in 2025.
Grammarly accounts, plans and support still run under the Grammarly name, so a complaint about a Grammarly charge or account goes to Grammarly support at support@grammarly.com, and a letter goes to Superhuman Platform Inc. at the San Francisco mailing address in the contact details above.
Is that Grammarly shared document email real?
It may be, but be careful with what is inside. Grammarly warns that its document-sharing emails can be misused: the email itself can be genuine while the shared document, which Grammarly does not create or review, holds the scam. Other emails only imitate Grammarly. Do not call numbers, click links or download files from a sender you do not recognise.
What do people complain about most at Grammarly?
Nothing has been reported about Grammarly here yet. Our research shows what typically goes wrong at writing software sold by subscription: annual renewals people did not expect, refund requests after a renewal, cancellations that do not stop the next charge, seats and plan changes on team accounts, accounts people are locked out of, and support that runs only by chatbot, ticket and email.
Renewal on your statement for a plan you thought was canceled? Open the first case, and the next Grammarly user who finds the same renewal has a case to point to.
What happens after I submit my complaint?
Your complaint gets its own public page on Complain.biz and we get to work: we bring it to the attention of Grammarly through emails, social media, paper complaint letters and other tools at our disposal.
And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.
Can other consumers help me with my Grammarly complaint?
Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with Grammarly can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
