Grammarly is a cloud-based[3] English-language writing-enhancement platform developed by Grammarly, Inc. The software was first released in late 2009. Grammarly's proofreading and plagiarism-detection resources[4] check against more than 250 grammar rules.[5][6][7]


Grammarly is an app that automatically detects potential grammar, spelling, punctuation, word choice, and style mistakes in writing. Grammarly's algorithms flag potential issues in the text and suggest context-specific corrections for grammar, spelling, wordiness, style, punctuation, and plagiarism. It is available via a browser extension for Chrome, Safari, Firefox, and Edge. Grammarly is available as an app for both iOS and Android; a premium service is available for a monthly payment.[8]

It was developed in 2009 by Alex Shevchenko and Max Lytvyn, in Kyiv.[7][9] The app is owned by Grammarly Inc. Brad Hoover is the company's chief executive officer.[10]

In 2018, a security bug was discovered in the Grammarly web browser extension that allowed all websites access to everything the user had ever typed into the Grammarly Editor.[11] Grammarly has claimed the security vulnerability was never used to access any customers’ account data.

Grammarly Keyboard[edit]

The Grammarly Keyboard is an Android and an iOS app that is integrated within the typing service.

For Grammarly Premium users, the keyboard will also suggest style improvements and vocabulary enhancements. The user can see the suggestions along the top of the keyboard, and can accept a change just by tapping it.[12]


In 2013, Grammarly was awarded the "Gold Award" from TopTenReviews with a rating of 8.88.[4][13]
