About Grammarly

Grammarly is one of the most widely used AI writing tools globally, with over 50,000 teams using the Business and Enterprise product. The core offering extends beyond grammar and spelling corrections to include full-sentence rewrites, tone adjustments, clarity scoring, and GrammarlyGO — its generative AI layer for drafting emails, messages, and documents from prompts. The platform integrates natively into over 500,000 apps and websites via browser extensions, desktop clients, and API integrations with tools like Microsoft 365 and Google Workspace. Grammarly's pricing consists of a Free tier with basic checks and 100 AI prompts monthly, a Pro plan at $12/user/month (billed annually) with advanced features and 2,000 AI prompts, and a Business/Enterprise plan starting at $15/user/month (billed annually) with centralised billing, team analytics, and enhanced governance. The Enterprise plan adds custom style guides, brand tone configuration, SAML SSO, and priority support. From a compliance and security perspective, Grammarly has a strong certification portfolio: SOC 2 Type I and Type II, ISO 27001, ISO 27002, ISO 27018 (PII in cloud), ISO 27701 (privacy information management), and ISO 42001 (responsible AI). Data is stored on AWS US East infrastructure. Grammarly is GDPR-compliant and provides DPAs for EU customers. Importantly, Grammarly does not sell user data to third parties and provides clear controls over data processing. For enterprises deploying Grammarly Business, key governance controls include an admin dashboard for seat management, usage analytics, and the ability to configure shared style guides. One consideration for highly sensitive environments is that data is hosted in the US on AWS, without an EU data residency option, which may be relevant for organisations processing special-category data under GDPR. Overall, Grammarly Business represents a mature, well-certified enterprise writing tool with a strong compliance track record.
