About MistScale

Living worlds need characters that remember.

MistScale is the cognitive layer for game NPCs. Persistent memory, evolving mood, per-player relationships, and grounded reasoning, wired into a single platform for studios building worlds that feel alive.

What we believe

Three rules we build by.

01 / 03

Memory first

An NPC that forgets is a stranger every session. Every interaction should change the character, the way it would change a person.

02 / 03

Truth over fluency

A character that invents lore breaks your world and your players' trust. MistScale NPCs answer from your canon, and admit what they do not know instead of making it up.

03 / 03

Tools, not toys

We build for studios shipping real games. SDKs, observability, and primitives that survive contact with production.
