About OperationDX department

We, the OperationDX division of Givery, Inc, help businesses automate their operations and improve productivity. Originally, we provided services through AI chatbots and AI FAQ services using our proprietary natural language processing and machine learning technologies.

With the introduction of ChatGPT technology, we expect to increase this speed exponentially. Therefore, we have been moving all the content of the services we have been creating to those using ChatGPT, and at the same time, we have launched a new service called "Corporate GAI Powered by GPT-4".

In the future, it will be impossible to work without ChatGPT.
Recognizing this major change, we at Givery have launched a new service called "Corporate GAI".

Corporate GAI" is a service that makes it easy to use ChatGPT within a company. Usually, when using an account issued by OpenAI, data is used for machine learning and information security is a concern, but with Corporate GAI, employees can use ChatGPT in an environment where data is not used for machine learning.

Through OperationDX, our mission is to revitalize Japan, which has begun to lag behind the rest of the world, as a digital superpower.
We believe that ChatGPT technology has the potential to change this situation in Japan.

We will continue to develop various businesses by utilizing cutting-edge technologies such as GPT and Generative AI.
We invite you to join us in creating a company that will change Japan.
