Become the protagonist in living novels that unfold around your actions. Create scenarios, import community-format Character Cards, and remix stories into your own. Become the protagonist in a novel that moves with you. Oncilo turns story ideas, excerpts, and Character Cards into playable scenarios. Choose who you are, step into the opening scene, and act freely. The story continues around your actions through prose, dialogue, relationships, and connected world details. LIVE THE NOVEL Take a role inside the story instead of watching from outside. Your actions shape the next scene, the characters around you, and the relationships that follow. REMIX THE STORY Change your role, the cast, era, relationships, factions, rules, or opening. Preview the changes, then save the Remix as a new scenario or update the current one. CREATE A PLAYABLE WORLD Start from a novel excerpt or synopsis, an original premise, or a world you want to explore. Oncilo creates a player role, main cast, opening scene, and setting collection that you can refine before the story begins. BRING YOUR CHARACTER CARDS Import community-format PNG Character Cards and bring their personality, greetings, and linked world information into Oncilo. KEEP EVERY VERSION TOGETHER Organize original, imported, remixed, and draft scenarios in one library. Continue refining a world or start its story whenever you are ready.
