GPTZero plans to join Superhuman

When Alex Cui and I founded GPTZero in January 2023, the goal was to preserve what's human on the internet.

We started out as an AI detector, but as AI rapidly changed the face of the internet, the need for authenticity has morphed and expanded.

In the last three years, we've refined our AI authenticity suite and are proud of the additional features and initiatives we’ve launched: AI Vision, which automatically detects AI content on social media; IstheInternetAI.com, which tracks AI usage across the web in real time, and a hallucination detector that's been used in investigations of Neural Information Processing Systems, a prestigious AI research conference, and professional firms, like EY and KPMG.

As our company's work has evolved, we've realized that authenticity isn't a finite verdict but rather something that you should be able to carry with you across every surface where you read, write, and create.

Why Superhuman

In 2025, we were connected with Grammarly co-founder and Superhuman product leader Alex Shevchenko. We bonded over a shared playbook: GPTZero and Grammarly experienced similar early, rapid product-led growth motions focused on user experience. Through this connection to Alex, we were introduced to Superhuman CEO Shishir Mehrotra.

As a start-up we’re always considering various potential paths forward that let us to stay true to our mission while growing our impact. In getting to know Shishir and the Superhuman team, we learned that they had a unique approach to what acquisitions can be: They aim for the larger established company to act as a “trampoline” to help the smaller company grow. This framing was immediately exciting to us. Joining Superhuman meant access to more resources, expertise, and customer insights to inform our products, not simply being absorbed into a bigger entity.

We also felt that now was the right moment to accelerate our path forward. Research we conducted with Graphite found that 50% of content on the internet is now AI-generated. As AI content increases, the value of genuinely good human work goes up. When anyone can generate a half-decent draft in seconds, there's now a premium on authentic expertise—and our whole product suite is built around that, from expert feedback that coaches students to write better, to tools that show the process behind a finished piece.

What's next for GPTZero

Joining Superhuman will open up surfaces to GPTZero that we haven't yet been able to reach on our own.

One of our largest and most consistent feature requests has been to bring AI detection directly into email inboxes, so people can quickly assess the authenticity and origin of what they're reading. Across Grammarly and Superhuman Mail, Superhuman already has an email user base in the millions. That's a surface GPTZero has always naturally resonated with, and one we haven't yet had the reach to serve at scale.

Our ability to serve educators and students will also grow when we combine forces with Superhuman. Feedback from teachers and students transformed our product into what it is today, and our commitment to this community remains strong. Superhuman also has longstanding experience in this space: Grammarly has been an essential writing support for students and institutions for over 17 years. When we combine forces, we can better help educators and students navigate what learning looks like in the age of AI.

Superhuman's suite will let us bring a fuller set of AI detection and process tracking tools into more interfaces, more seamlessly, and expand to more industries and domains than we could reach alone.

Together, Superhuman and GPTZero are building toward something bigger than either individual company: an authenticity layer that travels with you, wherever you read, write, and create. For our users, the mission to preserve what's human on the internet remains the same. What changes is how far we can take it.
