Grammarly rebrands as Superhuman with new AI suite
Grammarly has adopted the Superhuman name and has launched a four‑product AI platform anchored by Superhuman Go, uniting its writing tool, Coda’s workspace and the Superhuman email app under one brand.
Grammarly has changed its name to Superhuman and has introduced a four‑product platform comprising Superhuman Go (a new cross‑app AI assistant), the Grammarly writing tool, Coda’s collaborative workspace, and Superhuman Mail.
The move has consolidated earlier acquisitions into a single brand and signals a shift from a pure writing aide to a wider workplace AI offering.
The rebrand follows Grammarly’s purchase of email app Superhuman in July 2025 and its earlier deal for Coda, bringing email, documents and workflows under one umbrella.
The company said the change as an evolution into an AI‑native productivity platform, backed by its scale of 40 million daily users and more than one million integrations. A $1 billion non‑dilutive financing package from General Catalyst this year has supported the expansion.
Bringing agents to where people work
Superhuman Go is a proactive assistant that operates across over one million websites and apps, coordinating first‑ and third‑party agents to provide context‑aware help in the flow of work.
An Agents SDK has entered closed beta so partners and customers can build their own agents; early partners include Common Room, Fireflies, Latimer, Parallel, Radical Candor, Quizlet and Speechify.
Superhuman stated that Go features are available at no additional cost through 1 February 2026, with broader bundles now offered under the new brand.
What has changed for existing Grammarly users?
Most Grammarly functionality remains intact; the Grammarly button and underlines still appear in text fields. Users of the browser extension have been offered an option to switch to the new Go experience; generative features have then been handled by Go, with plagiarism and AI detection available via the sidebar.
Further, saved documents and settings have remained in place, and accounts and plans have continued to work as before.
Chief executive Shishir Mehrotra has said the Superhuman name reflects a platform designed to amplify, rather than replace, people’s work. Superhuman founder Rahul Vohra joined the company following the July acquisition.
