Superhuman is an AI-powered email client designed for professionals and teams who need to manage high volumes of email with maximum efficiency. Built around speed and keyboard shortcuts, Superhuman processes email up to twice as fast as traditional clients like Gmail and Outlook. The platform's AI features include Auto Drafts, which automatically write follow-up emails in the user's voice and tone, and Write with AI, which can compose, rewrite, shorten, lengthen, or improve emails from brief blurbs. Ask AI allows users to query their inbox in natural language, returning answers based on email content without manual searching. Auto Labels automatically classify incoming emails into customizable categories, while Auto Archive intelligently archives marketing emails and cold outreach to keep the inbox focused. Superhuman's Split Inbox feature organizes emails into separate streams for VIPs, team conversations, newsletters, and notifications. The platform integrates with CRM tools including HubSpot, Salesforce, and Pipedrive, and includes a Recent Opens Feed that shows when recipients open emails in real-time. Additional productivity features include Share Availability for scheduling without calendar links, Shared Conversations and Team Comments for collaboration, Snippets for reusable email templates, and Read Statuses across teams. Superhuman supports Gmail and Outlook accounts and is available on macOS, Windows, iOS, and Android.
