Score: 5.8/10 (Innovation: 4, Technical: 7, Documentation: 7, Utility: 5)

OpenHuman is an open-source, clean-room clone of Superhuman: a keyboard-first Gmail client for macOS with on-device AI, split inbox, snooze, send later, and an agent-ready CLI/MCP server. It's a substantial Swift-native desktop app that emphasizes local-first privacy and a rich feature set, though it's an early alpha and only runs on recent Apple silicon Macs.

Target audience: macOS power users and developers interested in local-first AI email clients
