Grammarly to acquire email client Superhuman to develop AI platform

Grammarly, a Ukrainian-based company based in Kyiv, has announced its intention to acquire Superhuman, the developer of a popular AI-powered email client. The acquisition is part of Grammarly’s new strategy to transform into a multi-product AI agent platform for productivity.

Superhuman is known for creating an email client that saves users time with intelligent features that speed up email. According to Grammarly, email is an ideal environment for integrating AI agents, as professionals spend more than three hours a day in email applications.

"We are moving towards a future where AI works where humans work," said Grammarly CEO Shishir Merotra. "With Superhuman, we will be able to offer a new experience for interacting with agents to millions of users."

Grammarly says its AI assistant now edits over 50 million emails per week across 20+ email services, including Gmail, Outlook, Apple Mail, and Superhuman. At the same time, Superhuman is actively implementing AI features: 94% of its users use them, and the speed of email processing increases by 72% on average.

Superhuman CEO Rahul Vohra emphasized that the merger with Grammarly will allow for a new format of working with AI agents directly in email tools, freeing up time for creative and strategic tasks.

The acquisition will further expand Grammarly’s ecosystem, which already includes Coda, a tool for managing AI agents that research, analyze, create, and share information. In the future, the company plans to introduce a platform that will allow users to work with multiple agents simultaneously. For example, when preparing an email, you could have a communications agent edit the text, a sales agent review the data, a customer support agent add context, and a marketing agent provide recommendations for product positioning.

Grammarly believes that this approach will help professionals achieve a threefold increase in productivity over the next five years.

Recall that Grammarly was founded in 2009 by three Ukrainians – Oleksiy Shevchenko, Maksym Lytvyn, and Dmytro Lider. The company recently raised $1 billion from venture capital fund General Catalyst.
