## Description

My own casting universe — Casto.
Create your dream cast and put them in stories only you'd write.
Watch their filmography grow into your own world.

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."
