Halen

Local-first macOS menubar writing assistant that never sends text to a server.

Desktopfree

Halen is a free, open-source macOS menubar writing assistant that fixes grammar and tone, expands shortcuts and drafts replies, running entirely on-device with Apple Foundation Models or local LLMs so text never leaves the Mac and there are no accounts or telemetry. It's aimed at macOS users who want AI writing help without their messages being sent to a cloud writing service.
