The story
Founded in 2014 as a premium email client focused on keyboard-shortcut-driven productivity for power users, Superhuman built a subscription model ($30/month) targeting professionals wanting to spend less time in inbox. The company expanded from Gmail-only to Outlook support in 2022 and added AI-powered drafting in 2024 as the generative AI wave reshaped productivity software. In July 2025, Grammarly acquired Superhuman to integrate its email client into a broader AI-powered writing and productivity suite, with Superhuman now operating as part of the Grammarly Platform alongside Coda.
