Show HN: An Open Source Superhuman Email Client Clone

Hi HN, I'm a long-time Superhuman user, and a few weeks ago I cloned it as a native Mac app.

It's keyboard-first, with split inboxes, reminders, and a built-in calendar. It's local-first, including the AI features that use local models shipped in macOS 27, with the option to use Claude/Codex subscriptions. It's extremely configurable, even down to the search weights, and comes packed with CLI/MCP if you want to use it with an agent.

This is my daily driver for email, but it's by no means a "stable" product. Use at your own risk. I'm also working on a mobile app to go along with it.

Enjoy.
