What Grammarly does

Grammarly is an AI-powered writing assistance platform founded in 2009 and headquartered in San Francisco, serving approximately 40 million individual users and 50,000+ organizations globally. The product spans a five-tier SaaS structure — Free, Pro ($12/member/month annual), Business, Enterprise, and Education licensing — with native distribution through browser extensions on Chrome, Firefox, Edge, and Safari, desktop applications for Windows and Mac, mobile keyboards for iOS and Android, and an AI-native document editor called Docs. The technology stack combines 15+ years of proprietary linguistic data with machine learning and generative AI to deliver grammar checking, tone detection, paraphrasing, plagiarism detection, and a growing suite of specialized agents (Proofreader, Paraphraser, Reader Reactions, AI Grader, Citation Finder, Resume Builder, AI Humanizer, AI Detector) across 20+ languages.

The go-to-market is hybrid: a freemium product-led growth motion drives individual acquisition and conversion to Pro, while a sales-led enterprise motion handles Business and Enterprise contracts with multi-year terms, dedicated support, confidential mode, granular roles and permissions, data loss prevention, and unlimited generative AI prompts. Distribution leverage comes from native integration with 1 million+ apps and programs including Gmail, Microsoft 365, Google Workspace, Slack, Salesforce, and Zendesk, plus proactive workflow automation through the 2025-launched Superhuman Go assistant. The company holds SOC 2 Type 1 and Type 2, ISO 27001/27017/27018/27701, GDPR, CCPA, and FERPA compliance certifications, with 256-bit AES encryption at rest and SSL/TLS in transit.

In October 2024 the parent company rebranded from Grammarly to Superhuman to reflect expansion into a broader AI productivity suite, with the Grammarly product now delivered through Superhuman Go and complemented by an Agents SDK and Agent Marketplace launched in 2025. In March 2026 Grammarly suspended its Expert Review feature and became the subject of a class action lawsuit alleging misappropriation of journalists' and authors' identities, a notable reputational and legal event that is shaping current operating risk. Leadership includes CEO Shishir Mehrotra (of the Superhuman parent), co-founders Max Lytvyn, Alex Shevchenko, and Dmytro Lider, and Chief Revenue Officer Matt Rosenberg.
