Founded in 2009 by Alex Shevchenko and Max Lytvyn, Grammarly built its initial product on advanced natural language processing that outperformed Microsoft Word's grammar checker by a wide margin, growing primarily through word-of-mouth and freemium distribution to reach millions of users who install it as a browser extension and desktop app. The company has successfully navigated the AI revolution in writing tools by expanding its capabilities ahead of the curve. Today's Grammarly goes far beyond grammar—it suggests rephrasing for tone and clarity, analyzes whether writing achieves its intended audience and goal, and integrates with over 500,000 apps including Gmail, Google Docs, Slack, and LinkedIn to provide real-time writing assistance wherever users write. Grammarly Business extends these capabilities to enterprise teams with shared style guides, brand voice consistency tools, and analytics on team communication patterns. Grammarly has reached 40 million daily active users and 70,000+ enterprise customers, generating $200M+ in ARR. The company raised $200M at a $13 billion valuation in 2021, though its IPO timeline has been repeatedly deferred. The emergence of ChatGPT and similar generative AI tools has intensified competition in the writing assistant space, but Grammarly's deep integration into users' daily workflows, its trust-based positioning (not generating text from scratch but improving human writing), and its enterprise customer base provide meaningful differentiation in an increasingly competitive market. ## Frequently Asked Questions ### What does Grammarly do?

Grammarly transmits text to its servers for analysis using encrypted connections and offers a zero-data retention option for enterprise customers where text processed for suggestions is not stored or used for model training — and Grammarly holds SOC 2 Type II and ISO 27001 certifications, providing the security assurance that regulated industries and enterprise IT and security teams require before approving widespread employee use. ### What is Grammarly GO and how does it extend beyond grammar checking? Grammarly GO is Grammarly's generative AI feature that drafts complete responses, emails, and documents from brief prompts — going beyond correcting existing text to generating new content based on context from the current writing task, integrating with the Grammarly extension so AI drafting and grammar/style checking work together in the same interface without requiring separate AI tools for generation and editing. ## Tags ai-powered, b2b, b2c, global, productivity, saas, collaboration --- *Data from geo.sig.ai Brand Intelligence Database.
