Let’s invent a future where humans and machines can collaborate to extend human creativity.

COTOBA DESIGN is looking for talented people in the field of natural language processing, and full-stack engineers who fully support excellent service implementation. Human resources with diverse expertise in fields other than natural language processing are also welcome.
“Dance until it rains.” Let’s create a world enriched by humans and machines through conversational interfaces.


The interface paradigm is shifting to the dialog type where the machine is close to the person and realizes the person’s thought rather than the person who knows everything the machine can do and gives instructions. COTOBA DESIGN will seek the best information and communication technology and AI technology to realize this.

Would you like to experience the fusion of the latest development methods, language processing, and robotics together? Let’s create an interface paradigm shift together.
