noco Inc. (Headquarters: Chuo-ku, Tokyo; Representative Director: Ken Horibe) has launched "Generative AI Type 2.0" for its AI customer support system "Helpdog" (https://helpdog.ai), which overhauls the question comprehension and information retrieval mechanisms of its AI chatbot "Generative AI Type."

This makes it easier to find related information even wi
