Mistscale
AI NPC with persistent memory and evolving relationships
The universal platform to manage and scale high-fidelity NPC AI. Persistent minds, evolving personalities, and Unity SDK integration for autonomous worlds.
Hey everyone, me and @rishabh_agrawal9 we are building MistScale, infrastructure for game studios to deploy NPCs with persistent memory and evolving relationships.
Problem:
Every NPC in games is stuck on repeat. Traditional game characters are scripted state machines ,same lines, same behavior, every single time you talk to them. And the newer "AI NPCs"? They remember a few facts about you, but that's it. No real relationship. No personality that shifts. No sense that the character actually knows you.
You can pour 40 hours into a game, and the blacksmith still greets you like a stranger. That always felt broken to us.
What MistScale does: MistScale gives every character a memory and an inner life.
They remember you. Not just facts, actual moments. The argument you had, the quest you helped with, the time you walked away. Every player builds their own history with every character.
The relationship grows. Trust, warmth, patience, these shift based on how you treat them. Help a character out and they open up. Disrespect them and they close off. Earn their trust and they'll share things they'd never tell a stranger.
Their mood is real. How a character feels changes how they speak, their tone, how helpful they are, what they choose to reveal or hold back. The same NPC feels different depending on your history together.
We're opening early access and genuinely want feedback from people who make and play games.
Two things we're chewing on:
Should studios get full control over a character's trust/mood values, or should we keep it simple with higher-level "personality" settings?
For the games you play — would NPCs that truly remember you actually change the experience, or is it a nice-to-have? Try the playground, break it, tell us what's missing.
