Grammarly Rebrands as Superhuman, Launches AI Assistant Superhuman Go

Grammarly is changing its corporate name to Superhuman, which it recently acquired, bringing together Grammarly, Coda, and Superhuman Mail under a single brand. 

With this, the company is moving from a writing-focused tool to a bigger productivity platform designed to help users work more efficiently across multiple apps.

The new Superhuman identity coincides with the launch of Superhuman Go, an AI assistant integrated into Grammarly’s existing browser extension. 

Users can now connect Go to apps like Gmail, Google Drive, Google Calendar, and Jira, allowing it to draft emails, suggest improvements, schedule meetings, and even log tickets automatically. 

Superhuman said it plans to expand Go’s capabilities to pull data from CRMs and internal systems to make suggestions even more contextually accurate.

“All Grammarly users can try out Superhuman Go right now,” the company said, adding that Pro subscriptions cost $12 per month (billed annually), offering grammar and tone support in multiple languages, while the Business plan costs $33 per month (billed annually) and includes Superhuman Mail access.

Superhuman is also exploring the integration of AI into Coda, its document platform, to automate content creation and enhance workflow. The company’s aim is to compete directly with productivity giants like Notion, ClickUp, and Google Workspace, all of which have launched AI-powered features in recent years.

CEO Shishir Mehrotra noted that “Superhuman represents a fundamental shift in how we think about AI at work. The name Superhuman reflects our belief that AI should amplify human capability, not replace it or force people to adapt to its limitations.

“Our vision is AI that makes every person better by working everywhere they work, understanding how they actually work, and bringing them what they need at the right time, so people can stop managing tools and start focusing on work that matters.”

Superhuman Go comes with a suite of first- and third-party agents accessible via the Superhuman Agent Store. These include connector agents that pull real-time data from tools like Google Workspace, Outlook, Jira, and Confluence; Grammarly writing agents that provide plagiarism checks, style suggestions, and reader insights; and partner agents from companies such as Quizlet, Fireflies, and Speechify. 

Users can customise Go with multiple agents, making the assistant a proactive collaborator rather than a passive tool.

Noam Lovinsky, CPO of Superhuman, explained the rationale behind Go:

“While other AI tools ask you to change how you work, Go learns how you work and meets you there. It’s the difference between having an AI tool you have to remember to use and having an AI partner that’s actively working with you.”

Superhuman has also introduced the Superhuman Alliance, a partner programme that provides technology and service partners with tools and resources to develop AI agents and deliver solutions to customers. 

Unlike traditional programmes that reward scale, the Alliance aims to enable partners of all sizes to innovate and contribute to the platform.

Despite the rebranding and new AI features, Superhuman stressed that existing Grammarly, Coda, and Superhuman Mail users retain full control of their data. The company does not sell user content or allow third parties to train AI models on it.

The Superhuman suite is currently available through paid plans, with Superhuman Go accessible via Grammarly’s browser extension on Chrome and Edge. 

Mac and Windows users will see support rolled out soon. For a limited period through February 1, 2026, all Go features are available at no additional cost, giving users a full preview of the platform’s productivity.
