Casto

Casto이란?

Casto turns your imagination into a casting universe. Build characters with profile and backstory, cast them into a premise you sketch out, and an AI screenwriter weaves a 5-episode serialized story around them. After each chapter you choose what happens next. Every series joins your personal universe — characters carry over, and the world keeps growing. For storytellers, daydreamers, and anyone who's wanted to direct their own show.
