Modern, campus, isekai, anime. Meet memorable characters, remix a scenario, and let your words and actions shape what happens next.
Step into the story. Become the one who moves it forward.
Oncilo is an AI roleplay and interactive storytelling app. You’re not just chatting with a character, watching anime, or reading a web novel that’s already been written: you take on a role in the story, write your own words and actions, take part in events, and explore different chapters and character side stories. As the story unfolds, check its current state and the changes each interaction brings to see how your participation shapes what happens next.
WRITE YOUR NEXT MOVE
A character invites you somewhere. An unexpected event unfolds. An unfamiliar journey lies ahead. What will you say, and what will you do? Write your response and actions to keep the story moving.
FOLLOW THE STORYLINE, EXPLORE NEW POSSIBILITIES
In scenarios that support Storyline, follow chapter paths, complete story goals, and gradually unlock new chapters and character side stories. Check the story’s current state and the changes after each interaction to keep track of your adventure.
KEEP YOUR FAVORITE STORY GOING
Conversations have no fixed turn limit. Stay in the same story, keep interacting with the characters, and explore new events and twists as your story continues to unfold.
TURN AN IDEA INTO A STORY
Start with an idea and create the characters, your role, the opening scene, and the world around them. You can also import compatible PNG Character Cards.
REMIX A STORY YOU LOVE
Use Remix to change a scenario’s setting, your role, or its opening and try a different direction. Preview your changes and save your own version.
