AI-powered writing assistant Grammarly is rebranding as Superhuman. Usually, when a company acquires another, the smaller brand is absorbed. Grammarly took a different approach after acquiring email client Superhuman in July.

Superhuman now unites Grammarly, Superhuman Mail, and the AI work assistant Coda (acquired by Grammarly in 2025) into A single productivity suite. The company has also launched a new AI assistant called Superhuman Go, which is included in every Superhuman plan tier and integrated into the Grammarly browser extension for Chrome and Edge.

“The Grammarly product will still exist, but we’re changing our company name to Superhuman. We’re also evolving from a single product to a suite that includes Grammarly’s trusted writing partner, Coda’s all-in-one workspace, Superhuman Mail’s AI-native inbox, and a new product called Superhuman Go,” the company said in a statement.

The Superhuman Go UI will look familiar to Grammarly users, with its sidebar for viewing suggestions, typing prompts, and accessing various AI agents.

“Superhuman Go works across every application and tab. But instead of a single agent that helps you write, Go has a whole team of agents that can brainstorm, fetch information, send emails, schedule meetings, and more. What makes Go special is (1) it works in all the apps you already use, and (2) it helps without you needing to ask. Wherever you are, Go will look for opportunities to say something better or do something faster,” the company added.
