About this app

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.

With Oncilo you can:

• Live inside the story as the protagonist.
• Create playable scenarios from excerpts, original ideas, or worlds you want to explore.
• Shape the player role, main cast, opening scene, and setting collection.
• Import community-format PNG Character Cards.
• Remix your role, cast, era, relationships, factions, rules, or opening.
• Organize original, imported, remixed, and draft scenarios in one library.

AI output can be inaccurate or unexpected. Review generated content before relying on or sharing it.
