Superhuman (superhuman.com) is an AI-powered email client built on a single premise: email should take half the time it currently does. Over 85% of Superhuman users opt in to its AI features after onboarding — a remarkably high adoption rate for an AI productivity tool. In July 2025, Grammarly acquired Superhuman for an estimated $825 million, with Rahul Vohra continuing as CEO and the product operating as an independent brand.
Key Features

- Write with AI — jot a few phrases, and Superhuman generates a complete email in your personal voice and tone, learned from your sent history
- Instant Reply — AI drafts a contextual response to every incoming email; edit and send, or ignore entirely
- Auto Drafts — Business plan feature that automatically writes follow-up emails without being prompted
- Ask AI — natural language search across your inbox, calendar, and the web; ask “where is the offsite?” and get an instant answer
- 100+ keyboard shortcuts — keyboard-centric navigation that eliminates mouse dependence for high-volume email users
- Split Inbox — automatically segments email into customized sections (Team, VIP, News, Calendar) to reduce decision fatigue

Is Superhuman Worth It?
At $25–33/month, Superhuman is a meaningful investment compared to free email clients. The ROI calculation depends on email volume: the company claims users save four hours per week on average. For executives, salespeople, or founders handling 100+ emails daily, that time saving pays for itself in under an hour of recovered productivity. For occasional email users, more affordable alternatives like Shortwave or SaneBox may deliver similar benefits.
