Superhuman Go
An assistant that works inside the apps you already use, sorting email, drafting replies in your voice and running custom agents on a schedule.

Why 3: it sorts mail, drafts replies and runs custom agents on a schedule or an event, but the maker says nothing happens without your approval. Not 4, because you decide what is sent.
What it does. Go offers writing help wherever you type, sorts incoming mail and pre-drafts replies using your calendar and connected apps, and helps prepare and follow up meetings. Paid plans let you build no-code agents that run as you type, on a schedule or after an event, and connect apps through MCP connectors.
Where it falls short. The product page doesn't detail which calendar actions are available. In January 2026 PromptArmor showed a prompt-injection flaw in Superhuman's email AI that could leak inbox contents; it has been fixed.
