Four engines. One integration.

Years at the frontier of social, entertainment & companionship AI — distilled into four production-ready APIs.

Persona Engine

Autonomous Persona Engine

Input a few lines of character definition. Get a fully autonomous companion with distinct voice, persistent memory, and natural emotional range — no prompt engineering required.

Custom persona live in <5 minutes

Monetization

Contextual Monetization Trigger

The AI knows when to sell. It reads emotional context in real-time and surfaces payment hooks — unlocked content, gifts, subscriptions — without ever breaking the user's immersion.

Avg. CVR uplift +38%

Adaptive Learning

Adaptive Reinforcement Engine

Every conversation makes the AI sharper. Continuous stream learning means the longer a user engages, the more addictive the experience — and the higher your LTV compounds.

ARPU compounds 3.2× by Day 30

Infrastructure

Enterprise AI Safety & Compliance

Multi-layer safety framework covering hallucination prevention, character consistency enforcement, and automatic filtering of illegal or policy-violating content. GDPR-compliant data isolation with zero cross-tenant leakage — so your platform stays safe, coherent, and audit-ready.
