Overview

Persona is a character intelligence system designed to treat characters as living systems — consistent, reactive, and expressive over time. It provides a structured pipeline for defining identity, generating populations, and enabling evolution across long-running worlds. Designers establish the genetic foundations of a setting, generate diverse casts using evolutionary algorithms, and allow characters to adapt through learning, memory, and interaction. Rather than relying on brittle scripting, Persona supports emergence within designer-defined constraints — producing believable variation at scale while keeping behaviour coherent over time.

Key Highlights
  • Evolutionary character generation using genetic algorithms
  • Modular pipeline from identity definition to runtime behaviour
  • Persistent memory and learning through interaction history
  • Designed for large-scale populations and systemic worlds

Capabilities

Core features & functionality

Foundation Studio

Define the genetic blueprint of a world by authoring DNA libraries that describe traits, roles, skills, personalities, and constraints.

  • Configurable DNA libraries and gene definitions
  • Attribute limits, weights, and constraints
  • Reusable templates for different worlds or genres

Character Forge

Generate diverse character populations using evolutionary algorithms guided by fitness, balance, and diversity goals.

  • Selection, crossover, and mutation pipelines
  • Fitness-driven population refinement
  • Seeded and constraint-based generation strategies

Adaptive Network

Enable characters to learn from experience, recognise patterns, and adapt behaviour through reinforcement and imitation.

  • Context-aware decision-making
  • Behaviour adaptation based on outcomes
  • Emergent tactics and strategies over time

Core Characteristics

Track and manage the physical and mechanical state of characters during runtime, including resources, stats, and conditions.

  • Health, stamina, energy, and morale systems
  • Derived stats and progression
  • State and status-effect management

Interaction History

Persistent memory system that records significant events and shapes future behaviour, relationships, and personality.

  • Event, emotional, and relationship memory
  • Significance-based retention and decay
  • Memory-driven behaviour and dialogue hooks
