Grammarly is a Ukraine-founded cloud-based typing assistant. It reviews spelling, grammar, punctuation, clarity, engagement, and delivery mistakes in English texts, detects plagiarism, and suggests replacements for the identified errors. It also allows users to customize their style, tone, and context-specific language.
Grammarly was launched in 2009 by Alex Shevchenko, Max Lytvyn, and Dmytro Lider. Grammarly is available as a standalone application for use with desktop programs, a browser extension optimized for Google Docs, and a smartphone keyboard.
Grammarly is developed by Grammarly Inc., which is headquartered in San Francisco, California, with offices in Kyiv, New York City, Vancouver, and Berlin.
