To encourage developers to build better chatbots, Seattle-based start-up, KITT.AI, has launched ChatFlow in private beta. ChatFlow framework makes it easier for developers to build better chatbots that can hold multi-turn conversations and work on multiple platforms. In 2015, Xuchen Yao was inspired to build KITT.AI when he realized there where "no good dialogue systems, and no good tools to create good dialogue systems," he said.
