Grammarly Rebrands to Superhuman and Launches New AI Suite

Grammarly announced this morning that it’s rebranding to Superhuman, which is the name of an AI-powered email service it acquired back in July. As part of this rebranding, the company is also launching the Superhuman suite, which includes the popular Grammarly proof-reading tool, the collaborative workspace Coda (another recent acquisition), Superhuman Mail, and a new Superhuman Go assistant.

With the Superhuman suite, the company wants to capitalize on Grammarly’s 40 million daily users to create a “unified ecosystem for AI-native work.” The company also wants to create an open agent platform that will be available with its new Superhuman Go assistant.

“The unified Superhuman platform streamlines AI experiences for greater productivity: Grammarly provides clear writing assistance, Coda offers AI-native workspaces for collaboration, Superhuman Mail organizes inboxes while agents draft relevant replies and highlight key information, and Superhuman Go connects data, coordinates agents, and offers timely assistance wherever work happens,” the company explained today.

The new Superhuman Go assistant will be able to assist users on the web and provide context-aware suggestions. Over 100 connectors are allowing Superhuman Go to pull data from Google Workspace, Outlook, Atlassian Jira, Atlassian Confluence, and other tools. The Superhuman Agent Store will also provide access to existing Grammarly writing agents and a new selection of specialized AI agents. “These agents help users plan, start, and execute important work, from retrieving information to generating content to providing expert feedback,” the company said today.

The Superhuman suite is now available on paid plans, but nothing is changing for existing users of Grammarly, Coda, and Superhuman Mail. The new Superhuman Go assistant is available in Chrome and Edge for all Grammarly and new Superhuman suite users, with Mac and Windows apps coming soon. All Superhuman Go features will be available for free through February 1, 2026.
