Korea's AI chat service Zeta faces copyright dispute over VTuber fan works and ads
Zeta, an AI chat service run by Korean company Scatter Lab, is in a copyright dispute: the platform posted a notice saying it received a copyright warning from ANYCOLOR, the agency behind VTuber group Nijisanji, and said it will delete works that use its intellectual property without authorization, without giving a count of affected works or a completion timeline, according to IT之家 citing 4Gamers. The report said numerous fan creations featuring VTubers from agencies including hololive, VSPO! and Milipro could still be found on Zeta. Separately, user investigations found the likeness of Nijisanji VTuber Kurumochi Meruto used in Zeta advertising, and an indie VTuber's image lightly altered in ads Zeta placed on Pixiv; Pixiv said it is switching ad-serving vendors and continuing to investigate. Zeta has required original characters only since January 23, 2026.
The dispute shows a generative-AI role-play platform running into VTuber copyright issues both in user fan works and in its own ad creative, with a gap between its original-character rule and content still searchable on the service.
