Open Source Superhuman Alternatives

Superhuman is a premium AI-powered email client designed for professionals who demand maximum speed and productivity from their inbox. Built around a keyboard-first workflow, it helps users reach inbox zero faster than any other email client — with users reporting an average of 4 hours saved per week.

At its core, Superhuman combines blazing-fast performance with intelligent AI features: AI-assisted email writing and replies, smart follow-up reminders, read receipts, and automated triage. The interface is deliberately minimal, keeping focus on the emails that matter most and eliminating the cognitive overhead of a cluttered inbox.

Superhuman integrates with Gmail and Outlook, fitting into existing workflows without disruption. For teams, the Business tier adds deep CRM integrations with HubSpot, Salesforce, and Pipedrive, as well as collaboration features and admin controls — making it a strong choice for sales teams, executives, and high-volume communicators.
