Wrtn Technologies, the South Korean consumer AI company behind one of the country’s fastest-growing platforms, recently announced the North American launch of OOC, an AI character chat and interactive storytelling platform. Available on iOS, Android, and Web, the service marks the company’s major expansion into English-speaking markets.
The name OOC stands for “Out Of Character,” a term from roleplaying culture for the moment a player steps outside the story to speak as themselves. It is the North American edition of Crack, Wrtn’s flagship interactive character AI chat platform, which has rapidly become a major revenue driver since its standalone launch in South Korea in April 2025.
Branded as “The Playable Anime,” OOC brings the sensibility of Japanimation or Japanese animation. It serves rich character arcs, dramatic world-building, and serialized storytelling into an interactive format. Users become the protagonist. Every choice shapes the narrative in real time.
Seyoung Lee, CEO of Wrtn Technologies, said, “Users aren’t just chatting with a character, they are entering a narrative world where they are the protagonist.” The platform’s AI functions like a dungeon master in a tabletop RPG, constructing narratives that respond to user decisions while generating text, images, and audio on the fly.
Unlike standard AI companion chatbots or text-based adventure generators, OOC is designed around narrative structure, including world-building, evolving plot arcs, and real-time multimodal content generation. The company calls this new category “playable anime,” positioning interactive AI fiction as a distinct form of entertainment.
OOC’s underlying platform has already been validated across two major Asian markets (Crack in South Korea and Kyarapu in Japan), building a large and highly engaged user base with strong daily retention. The North American launch incorporates localization insights from the company’s Japanese expansion, with storytelling conventions tailored for Western audiences.
