DUCK-E

AI voice assistant that talks back during rubber duck debugging sessions.

Webfree

DUCK-E is an open-source voice assistant that reinvents rubber duck debugging by actually talking back: it listens to a developer explain a bug, asks follow-up questions, offers suggestions, and can search the web for answers in real time. Built on the OpenAI Realtime API with a FastAPI backend and WebRTC audio, it includes persistent memory and spend caps to control API costs. It targets developers who debug out loud and want an assistant that responds rather than a silent object.
