00 / SYSTEM OVERVIEWSCROLL TO OBSERVE

CHARACTER INTELLIGENCE MODEL05 / SCENES

SIGNAL / 01ACTIVE

Memory becomes context.

Every encounter leaves a durable trace that can shape what happens next.

SIGNAL / 02ACTIVE

Personality shapes intent.

The same world state produces different choices for different characters.

SIGNAL / 03ACTIVE

The world changes the answer.

Characters reason from relationships, location, time, and authored game state.

SIGNAL / 04ACTIVE

Actions stay inside your rules.

Sentient only uses the tools, permissions, and boundaries you explicitly provide.

01 / THE RUNTIME

Intelligence that belongs in the world.

SYSTEM / ACTIVE01

Persistent memory

Characters retain what matters—people, places, promises, and consequences—across every encounter.

SYSTEM / ACTIVE02

Dialogue with intent

Conversation emerges from personality, knowledge, relationships, and the immediate state of your world.

SYSTEM / ACTIVE03

Contextual decisions

NPCs evaluate goals and surroundings, then choose from the actions your game explicitly makes available.

SYSTEM / ACTIVE04

Controlled actions

You define the boundaries. Sentient operates inside deterministic tools, permissions, and gameplay rules.

02 / MEMORY MODEL

Every encounterleaves a trace.

Sentient turns events into durable character context. Memories decay, strengthen, connect, and surface when they matter—without handing narrative control to a black box.

03 / ENGINES

Native to your workflow.

Unity

C# SDK / Package Manager

Godot

GDScript + C# / Addon

Integrate character state, world events, and allowed actions without rebuilding your gameplay architecture.

Local-first development tools. Production runtime observability. Predictable controls at every layer.

04 / DEVELOPER FIRST

Your world. Your rules.

Sentient is infrastructure, not a replacement for authored design. Give characters intelligence while retaining authority over lore, tone, cost, latency, and behavior.

Typed character and world state
Explicit action allowlists
Inspectable memory and decisions
Runtime safety and fallbacks
