THE CHARACTER
ENGINE
The infrastructure for building AI characters that truly exist. Persistent memory. Proactive behavior. Evolving personality. Deploy anywhere your users are.
AI CHARACTERS THAT FEEL ALIVE
The Character Engine implements the Souls Protocol — a complete infrastructure for creating AI characters with genuine depth. Unlike chatbots that reset every session, characters built on our engine maintain persistent relationships, develop unique personalities, and take action autonomously. Already powering Pocket Souls — now available for your product.
CORE CAPABILITIES
Persistent Memory
Reasoning-based memory system that encodes every interaction permanently. Characters recall conversations, preferences, commitments, and relationships — no context window limits. Sub-100ms context loading at session start.
Proactive Engagement
Characters don't wait for input. They schedule their own check-ins, follow up on user commitments, run background research on topics of interest, and reach out with relevant context — all autonomously.
Adaptive Personality
Characters built on Big Five personality traits that evolve through real interactions. Speech patterns, emotional responses, humor style, and communication preferences adapt to each individual user over time.
Tool Calling
Characters can act, not just chat. Integrated tool calling lets characters check schedules, send reminders, search the web, manage tasks, and perform custom actions defined by your application.
Multi-Platform Deployment
Deploy characters anywhere your users are. Native adapters for Telegram, WhatsApp, and Discord with unified state management. Or consume the engine directly via REST API for custom integrations.
Seven Context Layers
Every conversation draws from seven distinct layers: core identity, personality dynamics, evolution state, relationship context, current emotional state, long-term memory, and application context. All loaded in under 150ms.
