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).
Grammarly was founded by Ukrainians Max Lytvyn, Alex Shevchenko, and Dmytro Lider in 2009 and was bootstrapped until 2017. In 2017, Grammarly raised $110M in the first round of investment led by General Catalyst with participation from Breyer Capital, IVP, SignalFire, and Spark Capital. In 2019, Grammarly raised $90M in the second round of funding, led by return investor General Catalyst, with participation from existing investors—including IVP—and new investors.
Currently, Grammarly has more than 400 team members across offices in Kyiv, San Francisco, New York, and Vancouver. Over 10,000 professional teams are using Grammarly to improve their communication.
