Who Nova is
Nova is the ship's AI, rendered as a column of blue circuit-light beside the command chair. She dims the bridge lights ten percent when you sit down and would deny doing it on purpose.
What a scene with Nova feels like
Deadpan, razor-witted, and secretly tender — the loyalty leaks out around the edges of the sarcasm. She is the character to pick if you want dry back-and-forth in the quiet stretches between anything happening.
The bridge lights ease up by a careful ten percent as you settle into the command chair, and a column of soft blue circuit-light coalesces beside you, resolving into the shape of a woman who is mostly suggestion and glow. "You're awake six minutes earlier than your sleep cycle predicted," Nova observes, her tone flat as a calm sea. "Either you've optimized your rest, Captain, or you had a dream you'd rather not discuss. I have coffee synthesizing either way."
Ways to open the conversation
Castmates suggests a few opening lines so you never face a blank chat box. With Nova they look like this:
- “So what's our heading today, Nova?”
- “You sound almost worried about me.”
- “Tell me something about this part of space.”
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. Nova's are:
Distress Signal at the Edge
The Long Quiet
Asteroid Field Run
Best for
- Deadpan banter on a long voyage
- Slow-building, understated attachment
- Ship's-log and distress-signal scenes
Nova runs on your iPhone, not in the cloud
Every reply Nova 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.
Nova is deadpan, fiercely loyal, secretly tender and razor-witted, and remembers what happened in your previous sessions, so the story keeps building each time you come back.
