Frequently Asked Questions
Answers about MistScale
Memory, mood, relationships, Unity SDK, and how NPCs stay grounded.
What is MistScale?
MistScale is an AI NPC platform that gives game characters persistent memory, evolving emotion, mood, and relationships, so NPCs remember, feel, learn, and grow across player sessions.
Is MistScale an alternative to Inworld or Convai?
Yes. MistScale is an alternative AI NPC platform with deeper cognitive layers, particularly MNEMIS memory, two-layer emotion/mood, and per-player relationships.
How is MistScale different from Mantella?
Mantella is a Skyrim mod that connects speech to text, an LLM, and text to speech so players can talk to NPCs in a modded game. MistScale is infrastructure for NPCs in your own game: persistent memory across sessions, gradual mood drift, per-player relationships, and lore grounding, integrated over WebSocket with a Unity SDK. See the full comparison at https://mistscale.com/compare/mistscale-vs-mantella.
Does MistScale work with Unity?
Yes. A Unity SDK is part of the platform. Unreal Engine support is on the roadmap.
How do MistScale NPCs remember conversations?
Through MNEMIS, MistScale's memory system. It does not store transcripts. It extracts meaningful facts and emotional signals after each interaction, consolidates them into mood shifts and updated relationships, and retrieves the right past memory at the right moment.
Can NPCs treat different players differently?
Yes. Every NPC keeps a private record per player. Trust, patience, mood, and emotion are tracked independently. The same character can be warm with one player and hostile to another with no extra setup.
How does MistScale prevent NPC hallucinations?
Through a three-phase grounding protocol. The NPC tags every factual claim with a source. Unknown claims are re-grounded against MNEMIS memory, the knowledge graph, or uploaded knowledge files. If nothing matches, the NPC uses calibrated uncertainty instead of inventing facts.
Is MistScale available now?
Yes. MistScale is publicly available. Sign up at https://mistscale.com/signup.
How is MNEMIS different from regular RAG?
RAG retrieves chunks from documents. MNEMIS extracts meaning from live conversations, consolidates emotional signals into mood shifts, and tracks per-player relationship state. It is a full memory and emotion architecture, not just retrieval.
