Zeta Chat App Surpasses Netflix in Total Usage Time in Japan

In a remarkable achievement, Zeta, an innovative AI chat application developed by ScatterLab Inc., has secured the top spot in the overall usage time rankings for entertainment apps in Japan, combining both iOS and Android platforms. According to the latest findings from App Ape, an analytical service for the mobile app market, Zeta has outperformed major streaming services, including Netflix, TVer, Prime Video, and U-NEXT, during April 2026. This accomplishment signifies a growing trend among users who prefer interactive experiences over passive content consumption.

Interactive Storytelling Takes Center Stage

The success of Zeta reflects the shifting preferences among Japanese users, who are increasingly drawn to interactive storytelling experiences. Unlike traditional platforms that deliver content passively, Zeta encourages users to engage with AI characters, enabling them to collaboratively weave narratives. This immersive feature is resonating with a broad audience, reflecting a deep integration of this unique interaction into the lives of its users.

During the Golden Week holiday period, usage surged, with users averaging around four hours per day on the app, leading to an impressive weekly usage time of over 27 hours. These figures underscore the high level of engagement with Zeta, as the app’s active user count surpassed 750,000, showcasing its increasing popularity across the nation.

Expanding Community of Creators and Characters

As of May 2026, Zeta has amassed over two million registered users, with an astounding 9 million AI characters created within the app. These characters span a diverse array of genres, including fantasy, romance, daily life, and other-worldly reincarnations. Users are enjoying unique interactions with characters like a cold school idol or a pet cat that has taken human form. The creativity reflected in user choices is a testament to the platform's potential for generating personalized storytelling experiences.

Kim Jong-yoon, CEO of ScatterLab Inc., commented on this notable achievement, emphasizing the advancements made to the company's unique AI model that have contributed to Zeta's success in the competitive Japanese market.
