Grammarly, a leading AI assistant for communication and productivity, has announced its intent to acquire Superhuman, an AI-native email app known for boosting email efficiency. This strategic move accelerates Grammarly’s transformation into a comprehensive AI productivity platform, leveraging email as a central hub for intelligent, multi-agent collaboration to streamline professional workflows.
Grammarly acquires Superhuman to enhance its AI productivity platform.
Superhuman users send 72% more emails per hour with AI tools.
Email is Grammarly’s top use case, revising 50 million emails weekly.
Acquisition follows $1 billion funding and Coda acquisition in 2024.
AI agents will handle inbox triage, scheduling, and personalized responses.
Aims to create a multi-agent platform for enterprise productivity.
Grammarly’s acquisition of Superhuman positions email as a critical component of its AI-driven productivity suite. With professionals spending over three hours daily in their inboxes, email remains a foundational workplace tool. Superhuman’s AI capabilities, which enable users to respond one to two days faster and save four hours weekly, align with Grammarly’s vision of integrating intelligent agents into daily workflows. Shishir Mehrotra, CEO of Grammarly, says: “This is the future we’ve been building toward since day one: AI that works where people work, not where companies want them to work. With Superhuman, we can deliver that future to millions more professionals while giving our existing users another surface for agent collaboration that simply doesn’t exist anywhere else.”
Superhuman, valued at $825 million in 2021, has seen 94% of its weekly active users adopt its AI features, resulting in a 72% increase in emails sent and responded to per hour. The platform’s AI tools for scheduling, smart replies, and categorization enhance productivity, with AI-composed emails increasing fivefold in the past year. Rahul Vohra, CEO of Superhuman, says: “Email is the main communication tool for billions of people worldwide and the number-one use case for Grammarly customers. By joining forces with Grammarly, we will invest even more in the core Superhuman experience, as well as create a new way of working where AI agents collaborate across the communication tools that we all use every day.” The acquisition provides Superhuman with greater resources to expand into calendars, tasks, and collaboration tools.
Grammarly’s strategy focuses on creating an “AI superhighway” that integrates task-specific agents across over 500,000 applications and websites. The acquisition builds on Grammarly’s 2024 purchase of Coda, which provided a platform for AI-driven research, analysis, and collaboration. By incorporating Superhuman, Grammarly aims to deploy agents that triage inboxes, schedule meetings, conduct research, and draft emails in a user’s unique voice. A Grammarly study highlights that 66% of professionals expect a 3x productivity increase within five years, with industry leaders predicting up to 10x gains, driven by such agentic AI solutions.
With over 40 million daily users and $700 million in annual revenue, Grammarly is evolving beyond its grammar-checking roots. The $1 billion non-dilutive investment from General Catalyst in May 2025 supports its expansion into a multi-product company. The Superhuman acquisition, following the Coda purchase, positions Grammarly to compete with tech giants like Microsoft and Google, as well as startups in the AI productivity space. The integration of Superhuman’s team, including CEO Rahul Vohra and over 100 employees, ensures continuity of the Superhuman brand while enhancing Grammarly’s enterprise offerings.
Grammarly’s acquisition of Superhuman marks a pivotal step toward building an AI-native productivity suite, where email serves as a central hub for intelligent automation. By combining Superhuman’s email efficiency with Grammarly’s AI expertise, the company is poised to redefine workplace productivity for millions of professionals worldwide.
Grammarly is the trusted AI assistant for communication and productivity, helping over 40 million people and 50,000 organizations do their best work. Companies like Atlassian, Databricks, and Zoom rely on Grammarly to brainstorm, compose, and enhance communication that moves work forward. Grammarly works where you work, integrating seamlessly with over 500,000 applications and websites. Coda, the maker of powerful AI productivity tools, is now a part of Grammarly.
