Duplex Party

Duplex Party is an AI voice agent that lets users build software and steer development by talking.

Duplex Party is an AI voice tool that lets users build software by talking instead of typing. Users can speak to the AI, see and understand the work as it changes, and steer what happens next in real time. Both sides of the conversation stay in the system even when they overlap. The platform features Full-Duplex Code on a shared community virtual machine. It is designed for developers who want to stay focused on their work while collaborating with AI by voice.
