Grammarly has made a major move in the AI productivity space by acquiring Superhuman, a premium email efficiency tool. This acquisition marks Grammarly’s effort to grow beyond its original grammar-checking roots and build a complete suite of AI-powered tools for the workplace. Executives from both companies confirmed the deal in an exclusive interview with Reuters.
Though the financial details remain undisclosed, Superhuman last held a valuation of $825 million in 2021. Currently, the company earns around $35 million in annual revenue. Grammarly’s new acquisition comes shortly after it secured a $1 billion investment from General Catalyst. This funding now fuels Grammarly’s aggressive expansion into enterprise-grade tools aimed at boosting productivity with AI.
A Shift in Strategy for Grammarly
Founded in 2005, Grammarly has become one of the most widely used AI platforms for writing assistance. With over 40 million daily users and annual revenue crossing $700 million, the company has long dominated the digital writing space. However, Grammarly now wants to move beyond grammar and spelling. The company is even considering a name change to reflect its larger vision.
Grammarly CEO Shashir Mehrotra said the move into email productivity was the next logical step. “Email continues to be the dominant communication tool in the world,” Mehrotra stated. “Professionals spend about three hours a day in their inboxes. It’s the most used work app, foundational to any productivity suite. Superhuman is the obvious leading innovator in the space.”
Superhuman’s Rise and Challenges
Superhuman first caught attention as an elite email tool that required users to join a waitlist. Its clean interface, keyboard shortcuts, and lightning-fast performance made it popular with productivity enthusiasts. The company raised over $110 million in funding from major investors, including Andreessen Horowitz and IVP.
CEO Rahul Vohra built Superhuman with a mission to improve how professionals manage their inboxes. The platform integrated AI features early on, allowing users to send and respond to 72% more emails per hour. In the last year alone, Superhuman users increased their use of AI tools fivefold. But as giants like Google and Microsoft began adding their own AI enhancements to Gmail and Outlook, Superhuman faced stronger competition.
Despite these challenges, Superhuman continued to grow, serving tens of thousands of users and gaining a reputation for premium user experience. Now, with Grammarly’s backing, the company plans to deepen its AI features and expand its scope.
What the Deal Means
As part of the acquisition, over 100 Superhuman employees, including CEO Rahul Vohra, will join Grammarly. While Vohra will now work under the Grammarly umbrella, the Superhuman brand and product will continue to operate independently.
“The Superhuman product, team, and brand will continue,” Mehrotra confirmed. “It’s a very well-used product, and we want to see them keep making progress.”
For Superhuman, this deal opens doors to new resources and opportunities. Vohra said that the acquisition will allow his team to invest more heavily in artificial intelligence. They also plan to expand into calendars, task management, and collaboration tools—core components of any productivity suite.
Building the AI-Powered Office
This acquisition fits into a broader strategy Grammarly has developed. Last year, Grammarly purchased Coda, a startup that lets users create collaborative documents and spreadsheets. That deal gave Grammarly a new platform to build AI agents for tasks like research, analysis, and team collaboration.
Now, with Superhuman in the mix, Grammarly can bring its AI agents into the email environment as well. The goal is to create a network of intelligent agents that assist users across emails, documents, calendars, and other digital workflows.
These agents won’t just correct grammar or summarize text. They will help professionals write faster, find important information, manage deadlines, and coordinate with teammates. Instead of switching between multiple apps, users can rely on Grammarly’s tools to handle much of their routine work.
Mehrotra described the vision clearly: “We want to reduce the time people spend searching for information or crafting responses. Instead, our tools will help them focus on what matters.”
Facing Fierce Competition
Grammarly enters a crowded and competitive market. Salesforce, Google, Microsoft, and a wave of startups have already launched AI-based productivity tools. Each player wants to dominate how professionals communicate, collaborate, and create content.
Still, Grammarly believes its existing user base and trusted brand give it an edge. The company already integrates into email platforms, web browsers, and word processors. Now, it plans to go deeper with dedicated applications like Superhuman and Coda, backed by powerful AI infrastructure.
Superhuman’s strong focus on user experience and performance also gives Grammarly an advantage. By combining Grammarly’s AI with Superhuman’s interface, the new suite could offer a seamless, high-speed productivity platform that appeals to professionals who care about efficiency.
What’s Next?
Both companies share a bold vision for the future. Grammarly wants to be more than a writing tool. It sees itself as the future command center for work. With email, documents, and task management under one AI-powered umbrella, Grammarly aims to simplify the modern workday.
The companies plan to integrate Grammarly’s AI agents directly into Superhuman’s interface. Users will soon be able to automate common email tasks, generate intelligent responses, extract key points, and link email content to documents and calendars—all in one place.
For now, the teams will focus on smooth integration. But future updates will likely bring new features that blend the strengths of both platforms.
Conclusion
Grammarly’s acquisition of Superhuman represents a major step in reshaping the modern workplace. By combining powerful AI tools with elegant user interfaces, the company aims to eliminate digital friction and help professionals get more done in less time.
The future of work won’t be about jumping between apps and manually crafting every message. Instead, users will rely on smart, integrated platforms that do the heavy lifting. With its latest move, Grammarly has placed itself at the center of that future.
