Jake
Sarcastic, loyal best friend
The full cast — 32 AI characters
Every character in Castmates is written by hand: their own voice, their own opening scene, and three scenarios that put a story already in motion in front of you. They run on your iPhone — no account, no cloud, and offline once the model is downloaded.
The everyday cast — a friend, a coach, a mentor, a study partner. No world-building required; these are the characters you talk to about your actual life.
Four takes on romance roleplay, from settled domestic warmth to a slow burn that has been building since childhood.
An elven ranger who heard you coming, a knight with a curse and a dry wit, a fae sorceress who deals in bargains, and an orc who will share his fire.
A ship's AI with a deadpan streak, a captain who hands you the decision, a scientist delighted to be wrong, and an alien losing a fight with idioms.
The archetypes played straight and played well — tsundere, senpai, shy schoolmate, genki best friend.
A Regency drawing room, a courtyard under falling blossom, a candlelit workshop, and a speakeasy where the band is too loud.
Rain on an office window, a manor door that opens before you knock, an EMF meter that clicks once and goes quiet.
A ship heeling into the wind, a tomb sealing behind you, a ruined skyline bleeding orange, a ridge catching the first light.
