Email becomes central communication surface in company's vision for agentic future where humans and AI work together

This acquisition accelerates Grammarly’s evolution into an AI productivity platform for apps and agents, positioning email as a critical communication surface in the company’s vision of an agentic future.

Addressing the AI promise gap

AI promises to revolutionize work and boost productivity with immediate impact. But technology providers have simply bolted AI onto existing tools, fragmenting an already chaotic tech ecosystem and making professionals’ lives harder. The result is status-quo productivity, poor software investment returns, and companies falling behind competitors who’ve found better solutions.

Grammarly is taking a different approach. The company has built an “AI superhighway” that delivers writing agents to users across more than 500,000 applications and websites. Now, Grammarly is building a productivity platform with more agents that handle more tasks for that superhighway, bringing AI directly to users everywhere they work.

“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 as an agent-ready surface

Email is the number-one use case of Grammarly for professionals, with the AI assistant helping to revise over 50 million emails per week across more than 20 email providers, including Gmail, Outlook, Apple Mail, and Superhuman.

Superhuman brings more than productivity gains to the acquisition. Building on its success as a beloved product with impressive adoption, Superhuman is defining the future of email and evolving into a comprehensive workspace for agents. With 94% of weekly active users embracing AI, the productivity impact is measurable: users already send and respond to 72% more emails per hour after using Superhuman compared to before. Now imagine taking that efficiency even further with AI agents that triage your inbox, schedule your meetings, perform deep research over all your content, and write full emails in your own voice and tone. Imagine those agents reasoning, problem-solving, incorporating detailed context about your work, and interacting with other systems and agents.

“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.”

Building the agentic future

According to a Grammarly study, early signals indicate workers are ready for agentic AI, with power users seeing opportunities for AI to handle tasks autonomously, including agentic administrative support (44%), internal collaboration and coordination (39%), and strategic communications (36%). Despite current AI adoption, 66% of professionals expect a 3x increase in productivity within five years. Industry leaders are twice as likely to predict a 10x increase in productivity over the same time period, which begs the question of where those gains are going to come from.

The acquisition supports Grammarly’s broader vision where applications function as intelligent agents that collaborate with users. Combined with the company’s recent Coda acquisition, which provides a workspace for managing agents to research, analyze, create, collaborate, and share information, Superhuman completes a critical piece of the productivity puzzle.

Grammarly is evolving into a productivity platform for apps and agents, moving toward a multi-product company with hundreds of intelligent, task-specific agents. Email represents the ideal environment for this multi-agent assistance, with professionals spending more than three hours daily in their inboxes and email remaining foundational to any productivity suite.

The future platform will enable scenarios where users can work with multiple agents simultaneously. For example, while writing a customer memo, users could have Grammarly’s trusted communication agent handle spelling and grammar, while a sales agent ensures accuracy of sales facts, a support agent provides context about recent customer issues, and a marketing agent suggests optimal feature positioning.
