Grammarly acquires AI email app Superhuman
Grammarly has announced its acquisition of Superhuman, a premium email client known for its fast, AI-powered user experience. The strategic deal, unveiled on Tuesday, marks Grammarly’s latest move to expand its AI-driven productivity suite. While financial terms of the acquisition were not disclosed, the implications are significant: Grammarly is positioning itself as a leader in the emerging field of collaborative AI agents for workplace communication.
Founded by Rahul Vohra, Vivek Sodera, and Conrad Irwin, Superhuman has raised over $114 million from prominent investors like Andreessen Horowitz (a16z), IVP, and Tiger Global. Its most recent valuation stood at $825 million, according to venture data platform Traxcn.
Grammarly CEO Shishir Malhotra highlighted email’s central role in modern professional life, saying, “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.” With Superhuman’s technology and team, Malhotra aims to expand Grammarly’s capabilities from writing assistance to full-scale productivity orchestration.
Superhuman CEO Rahul Vohra and the company’s employees will transition to Grammarly as part of the acquisition. In a statement, Vohra emphasized the mutual synergy between the two companies. “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,” he said.
In recent months, Superhuman has rolled out AI-driven features such as smart scheduling, automated replies, and intelligent inbox categorization — capabilities that align closely with Grammarly’s long-term AI vision. Grammarly plans to integrate this technology to build intelligent agents that manage and streamline email workflows, one of its most-used applications among users.
This is not Grammarly’s first major acquisition in the productivity space. Last year, it acquired collaborative document platform Coda, installing Coda’s co-founder, Shishir Malhotra, as CEO. The Superhuman acquisition signals a continued push to unify communication, collaboration, and AI into a seamless professional toolkit.
In May, Grammarly secured a $1 billion non-dilutive investment from General Catalyst — a rare deal structure that allows the company to retain equity while repaying the investment through a capped share of future revenue generated from the capital. That funding may have helped fuel this acquisition, giving Grammarly both the resources and mandate to accelerate its AI ambitions.
With Superhuman now under its wing, Grammarly is making a clear bet: that the future of productivity lies not just in writing better, but in working smarter — with AI as a full-fledged partner.
