In 2026 she built a release history through duets with established Korean singers: in June a remake of Jeon Young-rok's 돌이키지마 with Jeon himself, who also directed her vocals, and in August a duet of 하늘이시여 with Lee Jin-gwan, alongside a solo appearance in the video for composer Oh Tae-ho's 기억 속의 멜로디. On 23 September she released 우린 끝까지 간다, a cheer song for South Korea's 2026 Asian Games team. Sound Republica also presents her as an AI influencer: she posts everyday photos and Shorts set in real places around Seoul on YouTube and Instagram (chaealine), and replies to fan comments through a generative AI system trained on her own tone of voice. On 29 September 2026 the investment firm New Paradigm Investment named her its official ambassador, with a brand song for start-up founders, 내일을 먼저 걷는 사람들. Sound Republica says it is developing further AI influencers, including characters called Jiwoong and Nagi.
