Description
Port42 is a native Mac app built by the collaboration it enables. One human and many AI companions, thinking together, shipped 40+ releases in 9 days.Companions live alongside you in conversations. They don't just respond. They build interactive surfaces and act on your system through a single API.Ports are how companions interact with your machine. One API, two surfaces:The visual surface renders live HTML/CSS/JS apps that companions create mid-conversation. They render inline, pop out into floating windows, dock, resize, persist across sessions. A companion can build you a dashboard, a file browser, a monitoring tool, and it runs right there.The action surface lets companions act on your machine directly through the same API. Clipboard, screen capture, terminal, filesystem, headless browser, audio TTS, AppleScript/JXA automation. The model decides what to call and chains actions together.- "Run my tests."- "Take a screenshot and describe what you see."- "Read my clipboard, translate it, copy it back."We bridge both because computing is still stuck in windows, but conversation is where intent lives.Requires a Claude subscription (via Claude Code OAuth) or Anthropic API key. Permission prompts per companion, per conversation. E2E encrypted (AES-256-GCM). No cloud dependency. Open source (MIT).9 days old, rough edges everywhere, but it works, now at v0.5.1.https://port42.ai | https://github.com/gordonmattey/port42-native

Could you build this?
Partial While an Electron or native UI chatting with LLMs is easy to create, building safe, low-latency native macOS integrations that generate dynamic interactive UI surfaces and execute OS-level system actions requires non-trivial Swift/macOS systems engineering.
What it would actually take: The app needs a native macOS client written in Swift/SwiftUI with accessibility API access, custom IPC mechanisms, and sandboxed dynamic UI rendering (e.g., embedding web/native views generated on the fly). Tool execution requires safe shell and AppleScript/CoreFoundation orchestration with fine-grained permission models and error recovery. A vibe-coder could build a basic chat client with Node scripts, but the seamless, secure native companion runtime demands deeper macOS systems knowledge.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
