What is Port42?

Port42 is a native Mac application that lets you work alongside AI companions in real-time conversation. The tool is designed for developers and creators who want to build things directly within the app, with AI actively participating in the process rather than just answering questions. It uses end-to-end encryption to keep your conversations private and is open source, so you can review or modify the code yourself. The app is currently in early development (v0.5.0), meaning features are still being added and refined. It's free to try with a freemium pricing model, making it accessible for experimenting with AI-assisted development and creative work on macOS.
