The shift to online work has roughly 1 billion professionals spending close to 3 hours managing email each day(opens in a new window). This works out to around 1 trillion human hours a year spent on email.
Superhuman’s goal is to reduce the time spent managing inboxes. They’ve used OpenAI’s API to build a suite of next-gen AI email products that are saving users time, driving value, and increasing engagement.
## The overflowing inbox
At any company, a large portion of the workforce (Superhuman estimates between 30–50%, across roles like finance, sales, and support) spend their days in and out of email, struggling with overflowing inboxes. It’s all too easy for emails to be overlooked, leading to delays, or worse, mishandled—leading to errors or even reputational damage.
Superhuman got its start solving this problem with a popular product that offered an array of built-in email automations and integrated with common email services like Gmail and Outlook. Then came AI, which presented the opportunity to take the company’s vision to the next level and completely transform the email experience.
> “Many of us write several novels worth of email per year. Between the time we spend, how much we read, and how much we write, email is the perfect place for AI to add massive value to peoples’ lives.”

## Reimagining the email experience with OpenAI
Superhuman is making rapid progress on Superhuman AI, which is powered by OpenAI’s API. They’ve already launched a large number of GPT‑driven features like:
From the start, partnering with OpenAI was a centerpiece of Superhuman’s AI roadmap, for several reasons:
## Getting to inbox zero 2x faster
Superhuman’s rollout of Superhuman AI has met with tremendous success, seeing high user adoption rates and faster workflows:
## Pressing “forward” on the future of email
“Imagine waking up to an inbox where every email thread has a one sentence summary and a draft reply. Simply hit send,” Vohra said. This might have sounded far-fetched just a few years ago. But Superhuman has built and launched this end-to-end experience with OpenAI’s API. Each email comes with an automatic AI-generated summary, and users can choose from several AI-drafted responses to send instantly. “Thanks to AI features like these, Superhuman has seen its user base grow rapidly over the last year, more than doubling the number of weekly new users.”
What’s next? Superhuman imagines a world where GPT‑based agents will soon be able to filter, triage, and respond to email automatically—scheduling meetings and appointments, and taking basic actions online and in the real world. The success of Instant Reply proves this agent-led email future is not too far off.
