Grammarly is making a bold move to expand its AI productivity vision, announcing this week that it will acquire Superhuman — the sleek, AI-native email client known for helping busy professionals reclaim hours from their inboxes each week.
The deal, which comes on the heels of Grammarly’s recent $1 billion funding injection from General Catalyst, underscores the company’s ambition to transform from a trusted writing assistant into a full-fledged AI productivity platform — where smart, specialized agents handle everyday tasks across multiple work surfaces.
Grammarly’s leadership sees email as the ideal starting point for this new multi-agent future. Today, Grammarly already helps professionals polish more than 50 million emails every week across Gmail, Outlook, Apple Mail, and more. With Superhuman in the fold, Grammarly gains a purpose-built AI email experience — one that already helps users send and reply to 72% more emails per hour, saving up to four hours each week.
“Email isn’t just another app — it’s where people spend significant portions of their workday,” said Grammarly CEO Shishir Mehrotra. “This acquisition brings us closer to an agentic future where AI works where people actually work, orchestrating multiple intelligent agents that reason, collaborate, and handle tasks across apps — starting with email.”
Founded by Rahul Vohra, Vivek Sodera, and Conrad Irwin, Superhuman has long been an exclusive darling of Silicon Valley productivity power users. The startup, last valued at $825 million in 2021, has raised more than $110 million from top investors including Andreessen Horowitz, IVP, and Tiger Global.
Superhuman’s team of more than 100 employees, including CEO Rahul Vohra, will join Grammarly to continue growing the core product while layering in Grammarly’s AI agent network. “Joining forces with Grammarly gives us the resources to double down on Superhuman’s vision and build the next generation of AI-driven collaboration,” said Vohra. “Email is the backbone of how we communicate — together, we’re building agents that can triage inboxes, schedule meetings, handle research, and write full drafts in your voice.”
The Superhuman deal follows Grammarly’s acquisition of Coda last year, which added a collaborative workspace for research, content creation, and sharing. Combining Superhuman’s AI-native email workflows with Coda’s document and task management platform, Grammarly is steadily piecing together an ecosystem for autonomous AI agents that can move fluidly across inboxes, docs, chats, and beyond.
The company’s broader ambition is to build an “AI superhighway” that connects more than 500,000 apps and websites, delivering intelligent, task-specific AI agents that handle everything from grammar and tone to research, sales enablement, scheduling, and strategy — without adding friction to users’ existing workflows.
The demand is clear: a recent Grammarly survey found that 66% of professionals expect a threefold boost in productivity from AI within five years, with industry leaders twice as likely to predict a tenfold leap.
While the companies have not disclosed the deal’s financial terms, the move positions Grammarly firmly in the race to shape the next wave of agentic AI — directly challenging giants like Google and Microsoft that are layering more generative tools into Gmail and Outlook.
Vohra hinted that the Superhuman roadmap now includes deeper AI capabilities for not just email, but also scheduling, task management, and cross-app collaboration, with Grammarly’s agents at the core.
For millions of professionals, the result could be an inbox that’s no longer a time sink — but the nerve center for smart, secure, and context-aware AI assistance that frees up time for deeper work and creative thinking.
“This is the future we’ve been building toward since day one,” Mehrotra said. “We’re not just bolting AI onto existing tools — we’re rethinking how work happens with agents that work for you, everywhere you already work.”
