CORE CAPABILITIES

Persistent Memory

Every interaction is permanently encoded. Characters recall past conversations, preferences, and commitments with no context window limits.

Proactive Engagement

Characters don't wait for input. They schedule check-ins, follow up on commitments, and reach out with relevant context on their own.

Adaptive Personality

Characters evolve through real interactions. Speech patterns, emotional responses, and behaviors adapt to each individual user over time.
