About
AI Fiction with Your Own Cast! Casto is where your imagination becomes fiction. Create the characters who live in your head — every detail, every quirk — then cast them into AI-written novels that unfold one episode at a time. Casto is an AI fiction app — half story generator, half interactive fiction — that lets you cast original characters into branching, multi-episode novels. — WHAT YOU CAN DO — • Cast your own characters. Design original characters with names, photos, MBTI, occupations, and backstories. Reuse them across an entire universe of stories. • Generate multi-episode novels. Sketch a plot in a line. Casto writes a full episodic novel starring your cast — in romance, fantasy, comedy, or thriller. • Shape the story's direction. Every chapter ends on a branching choice. Pick the path, and the next episode unfolds from there. • Build a universe, not just a story. Every character you make joins your personal casting universe. Cast them into new stories, watch storylines intersect, and grow a world only you could imagine. — HOW IT WORKS — 1. Create your characters — name, photo, MBTI, occupation, backstory. 2. Cast them as leads in a new story (romance, fantasy, comedy, or thriller). 3. Steer each chapter with a branching choice. Casto writes the next episode around your call. 4. Reuse your cast in future stories. Your universe grows. — WHAT MAKES CASTO DIFFERENT — Most AI writing apps forget your characters the moment a story ends. Casto doesn't. Every character lives in your personal casting universe and can return as a lead, a love interest, or a foil across as many novels as you want to write. Less prompt-tweaking, more reading the fiction only your characters could star in. — WHO IT'S FOR — For readers who've always wanted to write the fiction they love. For writers who never tire of casting new leads. For anyone who has ever closed a book wondering, "what if my own character had been the lead?" Casto turns "what if" into "next episode."
