Grammarly

Grammarly is an AI-powered writing assistant used by over 30 million people daily to improve grammar, spelling, clarity, tone, and style across all types of writing. Founded in 2009 in Kyiv, Ukraine by Max Lytvyn, Alex Shevchenko, and Dmytro Lider, Grammarly has grown into one of the most widely installed browser extensions in the world, working across Gmail, Google Docs, Slack, LinkedIn, Twitter, and virtually every web-based text field. The platform uses advanced natural language processing to offer real-time suggestions — correcting errors, improving word choice, adjusting formality, and detecting plagiarism. Grammarly Business adds team consistency features, style guides, brand tones, and admin controls. In 2023, Grammarly launched GrammarlyGO, its generative AI tool for drafting, rewriting, and ideating content from prompts. Grammarly Free covers essential grammar and spelling. Grammarly Premium ($12/month) adds advanced clarity, engagement, and delivery suggestions. Grammarly Business starts at $15/member/month for teams. The platform is particularly popular with non-native English speakers, students, professionals, and content creators who write frequently.
