Grammarly to Acquire Superhuman, Advancing Its Vision for an AI-Driven Productivity Platform

Grammarly, the trusted AI assistant for communication and productivity, has announced its intent to acquire Superhuman, the AI-native email application known for helping users respond faster and reclaim hours every week from email tasks. This strategic acquisition strengthens Grammarly’s mission to evolve into a comprehensive AI productivity platform—positioning email as a critical interface in the future of agent-powered work.

Bridging the Gap Between AI Promise and Productivity

While AI continues to promise transformative gains in productivity, most solutions remain superficial—layered onto existing tools in ways that often complicate workflows. The result? Disjointed software ecosystems, stagnant productivity, and diminishing ROI for businesses.

Grammarly is taking a more integrated approach. By building what it calls an “AI superhighway,” Grammarly brings its intelligent writing agents to users across more than 500,000 apps and websites, embedding AI where professionals already work. With the addition of Superhuman, Grammarly is expanding that vision—creating a productivity ecosystem powered by multiple agents that act in coordination, directly within the tools people use daily.

“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,” said Shishir Mehrotra, CEO of Grammarly. “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. Email isn’t just another app; it’s where professionals spend significant portions of their day, and it’s the perfect staging ground for orchestrating multiple AI agents simultaneously.”

Email: A Launchpad for Multi-Agent Collaboration

Email remains the top use case for Grammarly users, with the platform enhancing over 50 million emails weekly across providers like Gmail, Outlook, Apple Mail, and Superhuman. Now, Superhuman brings more than advanced productivity tools—it offers a next-generation, agent-ready workspace.

With 94% of weekly users already embracing AI features, Superhuman users have seen measurable impact: a 72% increase in email response rate per hour. This performance lays the foundation for AI agents that go beyond assistance—triaging inboxes, scheduling meetings, conducting deep research, and drafting emails that match a user’s voice and tone.

“Email is the main communication tool for billions of people worldwide and the number-one use case for Grammarly customers,” said Rahul Vohra, CEO of Superhuman. “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. These kinds of agents will free us all up to be more creative, strategic, and closer to achieving our human potential.”

Paving the Way for Agentic AI

Grammarly research shows strong momentum toward agentic AI. According to a recent study, early adopters see significant opportunity for AI agents in tasks such as administrative support (44%), internal collaboration (39%), and strategic communications (36%). Two-thirds of professionals expect productivity to triple within five years, with industry leaders anticipating gains as high as 10x—a signal that true transformation requires deeper AI integration.

This acquisition follows Grammarly’s recent purchase of Coda, adding a flexible workspace where agents can analyze, create, and collaborate. Now, with Superhuman as part of the ecosystem, Grammarly gains a key channel to deploy its vision: an intelligent, agent-driven productivity suite where applications serve users in real time.

The future platform aims to support simultaneous, multi-agent workflows. Imagine drafting a customer memo with Grammarly managing tone and clarity, a sales agent checking accuracy of deal data, a support agent pulling in the latest customer history, and a marketing agent refining value propositions—all working together to deliver a smarter, more cohesive output.

Grammarly’s evolution into a multi-product platform for communication and productivity marks a major leap forward in enterprise AI, bringing real value to the everyday work of professionals across industries.
