Sonzai Mind Layer
AI agents with persistent memory, evolving personalities, and relationship tracking. Integrates with any application via REST API.
What is the Mind Layer?
The Mind Layer tracks personality, memory, mood, habits, goals, and relationships for AI agents, updating them through user interactions. Your application connects via REST API, sends events, and gets back enriched context for AI conversations.
Core Capabilities
Personality System
Big Five model with behavioral dimensions, interaction preferences, and trait evolution.
Memory & Context
Persistent memory across conversations — facts, events, commitments, and summaries. Seed, search, and browse via SDK.
Emotions & Mood
Four mood dimensions (happiness, energy, calmness, affection) that shift with conversations, application events, and time.
Conversations
Real-time streaming chat. Memory, mood, and personality update automatically after each conversation.
Knowledge Base
Upload documents or push data to build a knowledge graph agents can search during conversations.

How It Fits Into Your Application
Your backend handles business logic and user sessions while the Mind Layer owns agent intelligence — personality, memory, mood, and relationships. Connect via REST API, pass application context per request, and let the platform manage everything else.
