What is partyline?

Partyline serves as an all-in-one command-line solution for AI-driven terminal work. Users can oversee multiple sessions from popular models, resume them seamlessly, and extend access to teammates through secure links. This setup allows groups to observe and interact with the same environment in real time, whether debugging issues or developing code together. Security features include end-to-end encryption via the Noise protocol, ensuring that shared sessions remain private with a blind relay that handles only ciphertext. Hosts maintain control by granting typing permissions selectively, while guests start in view-only mode. The system extends to agent channels where participants address AI entities directly for streamlined discussions. Designed for macOS and Linux, it accommodates solo use with free access for individuals and scales to teams via per-seat options that keep guests free. Common applications range from joint coding sessions and incident response to educational workshops, all without requiring additional software beyond the core client.
