Grammarly is an American-based Ukrainian technology company that provides a digital writing assistance tool. It detects spelling, punctuation, and other common errors in texts.

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.[4][5]


It was developed in 2009 by Ukrainians Alex Shevchenko, Max Lytvyn, and Dmytro Lider.[1][2] The backend grammar engine was written in Common Lisp.[6] The app is owned by Grammarly, Inc., of San Francisco, California.[7]

In May 2017, the company raised $110 million in its first round of funding.[8] In October 2019, the company raised $90 million in a second round, at a valuation of more than $1 billion,[9] becoming the first unicorn from Ukraine.[10]

In 2018, Grammarly launched the beta version of a browser extension that works in Google Docs.[11]
