Background: Why 'Authenticity' is a Challenge in X Operations in the Generative AI Era

X has become established as a means for businesses to communicate their expertise and service value to prospective customers. However, the daily burden of selecting posting themes, refining text, and maintaining consistent posting often leads many businesses to abandon their efforts.

While the spread of generative AI has made content creation more efficient, new challenges have emerged, such as AI-generated text becoming uniform, the sender's own voice and context becoming diluted, and the initiative in communication shifting towards the service provider.

SebaschaNS is a service that addresses this challenge of 'balancing efficiency with authenticity' by supporting the continuation of X operations while preserving the sender's context and words. This signage advertisement is being implemented as a launch initiative to broadly communicate this proposition.

President's Comment

Yosuke Kono, President and CEO

SebaschaNS is a service that supports the continuation of X operations while preserving the sender's context and words. The reason for placing signage advertisements before the official release is that we wanted to deliver this service together with those who are actively posting on X. We chose Akihabara Station because it is a place frequented by individuals with high interest in IT and technology, making it a suitable touchpoint to deliver a new option for X operations utilizing generative AI. Amidst the spread of generative AI, how can we balance posting efficiency with authenticity? We hope this will be an opportunity for those interested in this question to learn about SebaschaNS.
