Grammarly Inc., the startup best known for artificial intelligence-powered proofreading and writing software, today announced its rebrand to Superhuman: a full-featured AI-native productivity platform.

Under the new name, Superhuman is still offering Grammarly, alongside document collaboration orchestrator Coda and premium email client Superhuman Mail, connected by powerful AI assistance. The company dubs this the Superhuman Suite, reflecting how much it aims to affect user productivity.

The rebrand arrives after Grammarly acquired Coda Project Inc., an AI document productivity platform in December and venture-backed AI-powered email client startup Superhuman Labs Inc. in July.

“For over 16 years, Grammarly has used AI behind the scenes to help people write better across every app they use,” Luke Behnke, Grammarly head of enterprise product, told SiliconANGLE. “But what started as writing assistance has grown into something much bigger: AI that proactively supports people wherever they work.”

The company has long been transforming itself into an AI-native platform for productivity. The rebrand and new offerings represent a significant milestone along this journey.

To bring all of this together, Superhuman is launching Superhuman Go, an AI assistant and agent that works across every tab and tool where work happens. It can offer proactive help and connect more than 100 apps to deliver information, offer suggestions and provide writing assistance.

Acting as the intelligent glue between apps and workflows, Go is designed to make use of AI agents to make collaboration and knowledge work easier. It can assist with emails by pulling account details from content platforms, remind users of support tickets and proofread writing so it sounds professional. For meetings, Go can remind users of what was discussed in the previous meeting notes and prep topics.

“The biggest problem we’re addressing is the gap that exists between intention and execution,” Behnke said. “Most people spend far too much time managing their tools and jumping between apps instead of doing their work. Superhuman removes that friction.”

Go is launching with AI agents available from the Superhuman Agent Store, a marketplace where users can get assistance from Grammarly, connector and partner AI capabilities. AI agents are autonomous intelligent systems that are the evolution of digital assistants, capable of taking action on the behalf of users by using software tools and pulling information from different sources.

In August, Grammarly released specialized agents for writing, which are now available in Go. These agents can provide expert writing assistance, including inspiration, subject matter expertise and predicting reader reactions. Specialized agents from partners can also provide additional tools and skills for Go, including from text-to-speech from Speechify Inc., study tools from Quizlet Inc. and smart meeting assistance from Fireflies.ai Corp.

Superhuman said it intends to expand the agents available in Go with more AI-powered productivity tools and partners over time.

Developers will be able to build on the platform, including adding connected agents for users with the new Superhuman Agents Software Development Kit now in closed beta mode.

“We’re not trying to be the only AI people use; we’re delivering the infrastructure that helps all AI work better together,” Behnke explained.

This could include companies building their own internal AI agents trained on enterprise data that can proactively deliver insights, automate workflows or work alongside employees by understanding their existing tools. Behnke said the SDK is designed to be an open, extensible platform that will put the best AI-enabled resources into customer’s hands.

For current Grammarly, Coda and Superhuman Mail customers nothing is changing about the products they use – they are just getting access to new capabilities. The Superhuman suite is available today on paid plans. Superhuman Go and connected AI agents are also available to all Grammarly and new Superhuman users on Grammarly’s browser extension for Chrome and Edge.
