Grammarly is no longer a clear-cut grammar checking tool. Instead, it is rebranding as Superhuman, a togetherness of 3 AI ventures that integrates email, workspaces, and agents. Grammarly introduces its vision for “proactive” AI that is at the focus of day-to-day operations. The rebrand breaks the company’s focus from perfecting sentences to choreographing whole workflows. The company is bundling its 3 main ventures under the rubric of Superhuman. With Superhuman Mail – a fully AI-native inbox, connecting workspace technology, and deep-rooted collaboration with Coda, and “universal” agents called Superhuman Go linked through services, there is no add-on upsell. The days of users relying on autocorrect and then an add-on toolbar are disappearing. Superhuman Mail lifts the FreeWrite metaphor, enabling users to schedule, produce, and follow up on work in one spot. Coda integration assists in handling the inbox like running a Google Doc, adding influencing workspace technology. Superhuman Go connects the projects with multi-step work, whether it’s sending updates, reporting metrics, or days of inter-departmental meetings. The rebranding effort additionally scatters any claim that Grammarly is a writing assistant.
From grammar checker to agentic AI: Grammarly’s path
Grammarly was an early embrace of generative AI, first through its conversational agent, GrammarlyGo, and special agents for citation checks, rubric-based feedback, targeted rewrites, and more.

The Superhuman Leap
These were tailored solutions geared for in-product interactions. The larger move in the market has been to “agentic” systems—autonomous or semi-autonomous AI capable of planning, tool-calling, and multi-step workflow execution. This is the force behind Microsoft Copilot in Microsoft 365, the addition of Gemini to every corner of Google Workspace, and OpenAI’s array of configurable GPTs and tool use. But this suite’s unique point of focus is the specific challenge of daily work around emails, documents, and project updates, where automation is ultimately defined in fewer clicks or seconds off a turnaround.
The productivity thesis underlying the Superhuman bet
The bet has a clear economic basis. Specifically, after this year Microsoft’s networked knowledge worker productivity thesis is this: according to McKinsey, generative AI could generate between $2.6 trillion and $4.4 trillion in additional annual value to the world economy by 2030. The greatest immediate impacts are forecast in consumer operations, marketing, sales, and software development. The aim there? Enable it to reduce communications and research. We want our share of that.
Email and documentation are still the beating heart of today’s work. While Superhuman believes that adding an AI-driven inbox to documentation workflows and cross-app agents can shrink the loop from “idea” to “sent,” the business will judge us not by the eloquence we inspire, but by the throughput we allow. This means less manual context-switching, smarter prioritization, fewer handoffs with the “logo on it” free version of the product. For companies, the bundling streamlines procurement, allowing IT to question a single suite with regular security, administration controls, and auditor work, rather than point solutions for work quality, drafting, generalization, and assignment automation.

Security, governance, and quality concerns with agentic AI
Agentic AI is raising difficult questions. For example, which models are running where? What data should be kept? Finally, how to monitor the prompts and the results? It adheres to a strict privacy policy. Companies expect credible responses on the discoverability of matrices, the option of zero retention, adherence to syndicated reporting structures like SOC 2 and ISO 27001, and finely tuned admin controls for departure prevention and safe access attempts. There’s still quality to remember. The capacity of a writing aide is only as effective as their understanding of the context. Hallucinations, overconfident summaries, or weird maps can degrade trust immediately. Despite this, our biggest deployments bind AI to certifiable sources, connections to our documents.
Brand strategy, competition, and differentiation ahead
Adopting the Superhuman name signals ambition: a unified brand for workplace AI, not just a feature-specific label. It also defines the company’s scope—email, documents, and cross-app assistance—to a user base overwhelmed by tool sprawl. Innovating under one flagship may become meaningful, so long as the pricing and onboarding are simple and the migration from legacy Grammarly plans is painless. Competition will be stiff. Incumbents bundle AI into the platforms workers already live in, from Outlook and Gmail to Docs and Word. Superhuman’s only route to differentiation is in speed, cross-application fluency, and a smooth user interface that works like second nature across distinct applications.
What to watch next as Superhuman seeks enterprise adoption
- Case studies in the first enterprise reach measuring time saved and error rates reduced, not words created.
- Deeper integrations with Microsoft 365 and Google Workspace.
- Transparency in model disclosures.
- Admin tooling grown up enough for regulated industries.
- User acceptance of AI agents that take action—particularly in the inbox—without causing a loop of approvals.
If Superhuman can make everyday work feel lighter and quicker, while building confidence, the rebrand will feel like a new working system, not only a brand change.
