Harness, a macOS workstation in Rust

I spend my days between email, messages and AI agents working on my projects. Harness brings all of that into one fast, local, native app.

What I did

• A unified inbox for email, iMessage and WhatsApp, indexed in a local database with full-text search.
• AI triage, summaries, drafts and tasks, sent only after approval.
• An Agents view that launches and resumes Claude Code sessions in built-in terminals.
• Calendar, notes and contacts, with passwords kept in the macOS Keychain.

Written in Rust with GPUI, the UI framework behind the Zed editor.
