Kakao is updating its messenger service, KakaoTalk, for the first time in 15 years by integrating OpenAI's ChatGPT and its own AI model, Kanana. This update was announced at the if(Kakao)25 conference, where CEO Chung Shin-a emphasized user experience improvements. The ChatGPT feature, powered by OpenAI’s GPT-5, will be available next month and allows users to access AI tools within KakaoTalk, connecting to other Kakao services. Kanana will launch after a closed beta test next month, providing real-time assistance, summarization, and search capabilities tailored for the Korean language. KakaoTalk's interface will be redesigned based on user feedback, introducing a feed-style friends tab, customizable friends lists, and custom chat folders. Additional features include AI-generated summaries for voice chats, message editing, community-style open chatrooms, and a new short-form video tab.
