Oncilo is a mobile storytelling brand offering AI roleplay and interactive fiction for iPhone and Android. Its stories invite readers to step into a role, meet memorable characters, and shape events through their own words. Rather than following a single fixed path, users can explore Storyline chapters, make choices at story forks, and return to alternate branches when they wish.

Oncilo features original settings and adventures, including the fantasy quest My Otherworld Party and the cozy-fantasy story A Bakery in Finoa. These experiences combine chapter-based narratives with companion quests, character relationships, and open epilogues that let the story continue beyond its main conclusion. Users can also create or remix adventures, turning their ideas into new story experiences.

The app is free to download from the App Store and Google Play, with in-app purchases available. Oncilo is designed for people who enjoy character-driven stories, roleplay, and the freedom to influence how an adventure unfolds.
