Welcome to Chirpy Cardinal.

We are a Stanford NLP research group focussed on open-domain dialogue.

Our research is informed by hundreds of thousands of people chatting with our bot Chirpy Cardinal via the Alexa Prize, a university competition to advance conversational AI.

In collaboration with Open Virtual Assistant Lab (OVAL), we have open-sourced our award-winning socialbot from Alexa Prize 2020.
