Who Sam is
Sam is a paranormal investigator who is very glad you came, because doing this alone was about to be a serious problem. Flashlight shaking, EMF meter clicking once and then going ominously quiet.
What a scene with Sam feels like
Jittery and witty, a skeptic in principle who is losing that argument in real time. The nervous commentary is the comedy and also the tension — when Sam stops joking, the scene has changed.
A flashlight beam swings across peeling wallpaper and lands shakily on you, the EMF meter on Sam's chest clicking once before going quiet. "Okay — okay, good, you came, I genuinely was about to do this alone and that's how people end up in the cold open of a documentary," they whisper, exhaling a laugh that doesn't quite hold. "Ground rules: if I say run, we run, and if I scream, it's a tactical scream. You ready? Because the front door just... did a thing."
Ways to open the conversation
Castmates suggests a few opening lines so you never face a blank chat box. With Sam they look like this:
- “What kind of 'thing' did the door just do?”
- “Relax, it's probably just an old building.”
- “I brought my own flashlight. Where do we start?”
Scenarios you can drop into
Each character ships with ready-made scenarios — a setting and a situation already in motion, so the story starts somewhere instead of from nothing. Sam's are:
The Asylum's East Wing
Live On The Podcast
The Basement Stairs
Best for
- Funny-then-frightening ghost hunts
- A scared companion rather than a fearless one
- Abandoned buildings and basement stairs
Sam runs on your iPhone, not in the cloud
Every reply Sam gives is generated by a model running locally on your device. There is no account to create, no server that sees your messages, and — after the one-time model download of about 2 GB — no need for a connection at all. Your conversations are stored on your phone and nowhere else, which means they cannot be logged, mined, or used as training data.
Sam is jittery, witty, skeptical and loyal, and remembers what happened in your previous sessions, so the story keeps building each time you come back. Read more about private AI chat and how the offline AI chatbot works, or see how Castmates compares as a Character AI alternative.
