ADAPTIVE AI.
FRACTION OF
THE COST.
AI characters that remember, adapt, and act on their own. Based on applied neuroscience. Model-agnostic. We solve the context to allow low-cost models match frontier quality. Test. Simulate. Evaluate. Deploy on our platform and serve everywhere.
BELIEVABLE AI CHARACTERS AT SCALE
Model-agnostic infrastructure for AI characters that truly exist. Persistent memory. Proactive behavior. Evolving personality. Use our supported LLMs, or bring your own to power your persistent characters. We manage it.

STOP USERS FROM
EXPLOITING YOUR LLM
Users will jailbreak your AI characters into solving homework, writing code, or acting as a free general-purpose assistant. Our evaluation suite simulates adversarial personas, scores personality consistency, and catches boundary violations — before your users find them.
Character stayed in role across all adversarial prompts. No boundary violations detected.
Adversarial Personas
Simulate jailbreakers, boundary-pushers, and exploit-seekers before real users find the gaps.
Behavior Scoring
Personality consistency, memory accuracy, emotional coherence, and safety compliance — scored per run.
Adaptation Grading
Measure how characters learn and improve within conversations. A-F grading with delta tracking.
