Superhuman

Originally launched in 2014 and acquired by Grammarly in October 2025 for an estimated $825 million, Superhuman has built a loyal following among founders, executives, and sales professionals who handle hundreds of emails daily and cannot afford to lose hours to inbox management.

Users consistently report getting through email twice as fast, replying 12 hours sooner on average, and saving more than 4 hours per week compared to Gmail or Outlook.

The platform's speed advantage is rooted in its 100+ keyboard shortcuts, which allow power users to triage, respond to, and action every email without reaching for the mouse.

Every function archiving, labeling, snoozing, forwarding, composing is accessible from the keyboard, and Superhuman's interface is deliberately minimalist to eliminate visual friction.

The platform connects to Gmail and Outlook accounts and syncs bidirectionally, meaning users keep their existing email infrastructure while accessing Superhuman's enhanced experience on top.

Superhuman's October 2025 AI update was its most significant to date, introducing three flagship automation features.

Auto Drafts uses AI trained on your historical email patterns to automatically write follow-up emails in your voice without any prompting, drafting responses to threads that need replies before you even open them.
