Grammarly is an American-based technology company that offers a digital writing assistance tool based on artificial intelligence and natural language processing.[4]

The software was first released in July 2009 in Kyiv, Ukraine. Grammarly is headquartered in San Francisco, and has offices in Kyiv, New York City, and Vancouver.[5][6]

Description and license types

Grammarly sometimes automatically detects potential grammar, spelling, punctuation, word choice, tone and style mistakes in writing, following standard linguistic prescription, but it also makes mistakes. Algorithms flag potential issues in the text and suggest context-specific corrections for grammar, spelling, wordiness, style, punctuation, and plagiarism, but many of the features are for premium users only. It is available as a web or desktop editor, or as a browser extension for Chrome, Safari, Firefox, and Edge, or as an app for both iOS and Android.[7] Premium service is available for a monthly or an annual payment.[8] The company also offers an enterprise tool called Grammarly Business.[9]


Grammarly was developed in 2009 by Ukrainians Alex Shevchenko, Max Lytvyn, and Dmytro Lider.[1][2] The backend grammar engine was written in Common Lisp.[10] The app is owned by Grammarly, Inc., of San Francisco, California.[11]

In May 2017, the company raised $110 million in its first round of funding.[12] In October 2019, the company raised $90 million in a second round, at a valuation of more than $1 billion,[13] becoming the first "unicorn" from Ukraine.[14]

On 2018, Grammarly announced support for Google Docs[15] but a security bug was discovered in the desktop web browser extension version of Grammarly that allowed all websites access to everything the user had ever typed into the Grammarly Editor. This bug affected Google Chrome and Firefox. Grammarly said that it has no evidence that the security vulnerability was used to access any customers' account data.[16]
