Description and license types

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

History

Grammarly was developed in 2009 by Ukrainians Alex Shevchenko, Max Lytvyn, and Dmytro Lider. The backend grammar engine was written in Common Lisp. The app is owned by Grammarly, Inc., of San Francisco, California.
In May 2017, the company raised $110 million in its first round of funding. In October 2019, the company raised $90 million in a second round, at a valuation of more than $1 billion. It also became the first Ukrainian unicorn.
In October 2018, Grammarly announced support for Google Docs.
In 2018, 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 and was rapidly fixed. Grammarly said it has no evidence that the security vulnerability was used to access any customers’ account data.
