What is Grammarly?

Grammarly is an AI writing assistant that provides real-time grammar, style and spelling corrections. Founded in 2009 and now used by more than 30 million daily users, Grammarly has grown into the standard solution for professional writing in English. The browser extension integrates into virtually every web app — from Gmail to LinkedIn — and gives suggestions directly while typing.

How does Grammarly work?

Grammarly analyzes text on multiple levels: correctness (grammar, spelling, punctuation), clarity (sentence structure, word choice), engagement (variety, word repetition) and tone (formal, informal, confident). The model understands context: it assesses whether a sentence is formal enough for a business email versus informal enough for a social post.

With the introduction of Grammarly GO (AI generation), Grammarly can not only improve texts but also generate new texts based on a description. This transforms Grammarly from a correction tool into a full writing assistant.
