Grammarly: World’s Most Innovative AI Company

Grammarly’s AI-powered digital writing assistant is used by 30 million people every day to make their communication clear and effective, wherever they type.



Grammarly develops an AI-based writing assistant that helps 30 million people every day write more clearly and effectively in English.

How does Grammarly work?

In building a product that scales across multiple platforms and devices—including a web editor, native desktop apps, an iPad app, mobile keyboards, add-ins for Microsoft Office, and browser extensions—Grammarly works to empower users whenever and wherever they communicate.

Underlying all of Grammarly’s product offerings is a sophisticated artificial intelligence system built to analyze sentences written in English. Grammarly’s computational linguists design cutting-edge algorithms that learn the rules and hidden patterns of good writing by analyzing millions of sentences from research corpora. 

When a user writes with Grammarly, our AI analyzes each sentence and looks for ways to improve it. Feedback and suggestions are delivered in four categories: correctness (grammar and writing mechanics), clarity (conciseness and readability), engagement (vocabulary and variety), and delivery (formality, politeness, and confidence).

Success story

Grammarly was founded by Ukrainians Max Lytvyn, Alex Shevchenko, and Dmytro Lider in 2009 and was bootstrapped until 2017.
