Superhuman is a premium email client designed around one goal: getting through email as fast as possible. It layers on top of your existing Gmail or Outlook account and replaces the interface with a keyboard-first experience — nearly every action has a shortcut, search returns results instantly, and features like Split Inbox, snooze, and follow-up reminders keep a busy inbox under control. Its AI writes and refines replies, summarizes long threads, and helps triage what needs attention.
The audience is deliberately narrow: executives, founders, salespeople, and others who live in their inbox and will pay to save time. That premium positioning sets it apart from free clients and from productivity-oriented apps like Spark or Missive, and from AI-native newcomers such as Shortwave. Superhuman’s differentiator has always been speed and craft rather than breadth of features.
In 2025 Superhuman was acquired by Grammarly, positioning it inside a larger AI productivity suite while continuing as a standalone email product.

Best For
High-volume email users — executives, founders, investors, and salespeople — who treat inbox speed as a real productivity lever and are comfortable paying a premium for it.
Limitations
The price is the obvious barrier: free Gmail and Outlook cover most people’s needs, and Superhuman only makes sense if your time is worth the subscription. It also demands a real learning investment to reach its promised speed, and since it sits on top of Gmail or Outlook, it isn’t an email provider of its own.
