Superhuman

Superhuman is a premium email client built for professionals who live in their inbox, now enhanced with AI capabilities that make email management dramatically faster. The platform is known for its blazing speed — every interaction happens in under 100ms — combined with keyboard-first design that lets power users fly through email without touching the mouse. Superhuman AI adds intelligent features on top of this speed foundation. The AI can draft complete email replies in your writing style, learning from your past emails to match your tone and voice. Write with AI generates full emails from brief instructions, while the AI-powered email summaries condense long threads into digestible key points. Auto Summarize provides one-line summaries of every email in your inbox, so you can triage at a glance. The Instant Reply feature suggests contextually appropriate one-click responses for common email patterns. Beyond AI, Superhuman includes powerful workflow features like Split Inbox (categorizing emails into streams), Send Later with smart timing optimization, Read Statuses showing when recipients open your emails, Snippets for templated responses, and Reminders that bring emails back at the right time. The platform works with Gmail and Outlook, supporting both personal and work accounts. Superhuman's onboarding includes a personal concierge session to configure the tool for each user's workflow. The email client has developed a cult following among executives, founders, and professionals at companies like Spotify, Shopify, and Airbnb who consider email a critical part of their workflow.
