Superhuman

Superhuman is the reference standard for executives and professionals processing a critical volume of daily email. Its paradigm is the eradication of the mouse: over a hundred keyboard shortcuts, sub-100-millisecond response times and the Split Inbox feature to divide your mail into separate work streams (team, clients, newsletters).

Its AI engine progressively learns your tone and writing style to draft follow-ups without prior instructions, summarise long threads and prioritise what genuinely needs a reply. The stated goal: reach Inbox Zero twice as fast as with a traditional client.

Following the Grammarly acquisition in 2025 and the integration of Coda under the unified Superhuman brand, the product has grown into a suite: Superhuman Go deploys proactive agents that operate across email, the browser and documentation tools. It runs on top of existing Gmail and Outlook accounts, at a premium price of $30–40 per month.
