Superhuman

Superhuman positions itself as more than an email client. Its site describes "Docs, Mail, and AI That Work Everywhere," and the product now spans three areas: Superhuman Mail for email, Superhuman Docs for collaborative documents, and Superhuman Go, an AI layer that works across desktop, mobile, and browser tabs. Pricing is split along those same lines, so a team can buy Mail on its own or adopt the full Suite.

In Mail, the AI drafts and rewrites messages, handles translations, and can auto-draft replies. Ask AI answers questions about your inbox, and custom auto labels sort incoming mail without manual rules. Teams get shared conversations, comments, and CRM data views pulled from HubSpot, Salesforce, or Pipedrive directly into the inbox. Offline support is listed for Mail, which matters when traveling or working with a spotty connection.

Docs covers the collaboration side: documents with tables, charts, kanban boards, and forms, plus automations and team comments. Superhuman Go extends the AI beyond the core apps, working across other sites and tabs through Grammarly for Chrome or Edge. Higher tiers add admin controls and compliance features for larger organizations, and there is a separate education offering for faculty, staff, and students.

Best for

• Sales and account teams that want HubSpot, Salesforce, or Pipedrive data visible inside their inbox
• Teams that collaborate on email through shared conversations and comments
• Professionals who want AI drafting, rewriting, and translation built into daily email work
• Teams replacing separate document tools with collaborative docs that include tables, charts, kanban, and forms
• Organizations that need admin controls, compliance features, and enterprise security
• Schools and universities, through the education offering
