Grammarly's strategy since 2023 has been to move from correcting text to doing work for the user. It launched GrammarlyGO generative features in 2023. It agreed to acquire Coda in December 2024 and made Coda co-founder Shishir Mehrotra CEO. It closed the Superhuman Mail acquisition in July 2025 and rebranded the company as Superhuman in October 2025, when it launched Superhuman Go, an assistant that runs first- and third-party agents across apps. In 2026 it added partner agents from Box, Gamma and Wayground to Go, rebuilt Coda as Superhuman Docs, and agreed in June to acquire GPTZero to add AI detection and authenticity tools. General Catalyst's $1 billion in 2025 pays for sales and marketing, so the company's own cash can go to acquisitions.
Grammarly runs a freemium subscription model. The free browser extension and apps give basic spelling and grammar fixes and pull in tens of millions of users. Revenue comes from people upgrading to the paid individual plan (Premium, later renamed Pro) for full-sentence rewrites, tone changes and more generative AI prompts, and from organizations buying team, business and enterprise plans that add admin controls, style guides, brand tones, analytics and security features. Grammarly for Education sells licenses to schools and universities. Since the 2025 rebrand, the parent company Superhuman also sells Coda/Superhuman Docs, Superhuman Mail and Superhuman Go, and bundles them into suite plans. The company does not publish a revenue breakdown by product or customer type.
