Grammarly has announced that it is acquiring Superhuman, an AI-native email app. This acquisition has been intended to accelerate the company’s evolution into an AI productivity platform for apps and agents, by positioning email as a critical communication surface in the company’s vision of an agentic future.
“This felt like peas in a pod,” Grammarly CEO Shishir Mehrotra told Newsweek. “I had a view on why we could reinvent documents, and [Superhuman Founder and CEO Rahul Vohra] had a view on why he could reinvent email.”
Grammarly states that while artificial intelligence promises to “revolutionize work and boost productivity with immediate impact,” technology providers often simply “bolt AI onto existing tools, fragmenting an already chaotic tech ecosystem and making professionals’ lives harder.”

Grammarly has taken a different approach by building an “AI superhighway” that delivers writing agents to users across more than 500,000 applications and websites. The company is now 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,” Mehrotra said. “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.”
Superhuman was founded by Rahul Vohra, Vivek Sodera, and Conrad Irwin. The company raised more than $114 million in funding from backers including a16z, IVP, and Tiger Global with its last valuation at $825 million, according to data from venture data analytics firm Traxcn. Following this deal, Vohra and other Superhuman employees will move over to Grammarly.

“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,” Vohra said in a statement. The company had also in the past few months released AI-powered features related to scheduling, replies, and categorization.
Last year, Grammarly acquired collaborative productivity software Coda, and as part of the deal, promoted Coda’s co-founder Shishir Mehrotra to CEO.
Grammarly had also recently secured $1 billion in funding from General Catalyst’s Customer Value Fund (CVF). The company said it would use these funds for product innovation, scaling its sales and marketing, and making strategic acquisitions. Following this funding round, Mehrotra said it was important for the company to bet big on product development and growth strategies as it transforms from being a single-purpose agent to an agent platform. He also stated that while the company has plans to go public, there are no immediate plans for it. He emphasized the focus on innovation with new products and growth.
