Grammarly just made a bold move.
The writing assistant giant has officially acquired Superhuman, a sleek AI-powered email client, in a strategic bid to beef up its productivity suite with smarter communication tools.
Why This Acquisition Matters
If you’ve ever wished your email could write, organize, and even think for you, this partnership might make that dream a reality.
Grammarly has always been more than a spellchecker.
With this acquisition, the company signals it’s diving headfirst into a world where AI agents handle your inbox, meetings, and more, right from your email.
What We Know So Far
- The financial terms? Not disclosed.
- Superhuman had raised over $114 million, with big-name investors like a16z, IVP, and Tiger Global backing it.
- Its most recent valuation? $825 million, per Traxcn.
- Superhuman’s CEO Rahul Vohra, alongside much of his team, will now be joining Grammarly.
A New Era for Email and AI Agents
In a statement, Grammarly’s CEO Shishir Malhotra emphasized that email isn’t just another tool, it’s a daily hub for most professionals.
“Email is the perfect staging ground for orchestrating multiple AI agents simultaneously,” Malhotra said.
Imagine this: AI agents summarizing your inbox, drafting replies, organizing meetings, and collaborating with other AI across your apps, all inside your email.
That’s the vision Grammarly is chasing.
Superhuman already dipped its toes into AI features recently, rolling out tools to:
- Auto-schedule meetings
- Generate smart replies
- Sort and categorize emails
Now, paired with Grammarly’s natural language engine, those features could scale into something even more intuitive and powerful.
What’s in It for Users?
For Grammarly users, this could mean:
- AI that doesn’t just suggest grammar fixes but takes real action.
- Email writing that feels like your own voice but on autopilot.
- Smarter tools inside the platforms you already use every day.
For Superhuman fans?
The app won’t be going anywhere.
In fact, Rahul Vohra says joining forces with Grammarly means doubling down on building a seamless, intelligent email experience.
“By joining forces with Grammarly, we’ll invest even more in the core Superhuman experience,” said Vohra.
Grammarly’s Bigger AI Vision
This isn’t Grammarly’s first big leap.
In 2023, the company acquired Coda, a collaborative productivity platform, and promoted its co-founder Malhotra to CEO.
In May 2025, Grammarly secured a $1 billion non-dilutive investment from General Catalyst.
Instead of giving up equity, Grammarly will repay the funds through a portion of revenue generated using the investment, keeping control while accelerating growth.
What Could Be Next?
While Grammarly hasn’t explicitly laid out a roadmap, signs point to an AI-powered workplace assistant that lives where you work: email, docs, chat tools, and beyond.
If that sounds a bit like Microsoft Copilot or Google Gemini, you’re not wrong.
But Grammarly’s move with Superhuman could give it an edge in personalization, simplicity, and cross-tool collaboration.
