Living Memory
Eigenstate
She remembers you the way a person would.
Memory, for a human, is not a database lookup — it is triggered by recognition. Eigenstate gives a digital human the same. Within a conversation she holds a living working memory of the exchange; across visits she recognises a returning person and recalls who they are and what was said — memory summoned by recognition, the way we actually remember one another.
Every person she has met is a stable state she can be collapsed back onto by a single cue. It is what turns a series of encounters into a relationship.
The technology
A voice-biometric embedding identifies a returning speaker from their voice alone; recognition triggers retrieval from a persistent, identity-keyed memory and re-injects it into the live context. Two tiers work in concert — a volatile working memory within a single conversation, and durable episodic memory that survives across visits.
Why it matters
Presence without memory resets to a stranger every time. Eigenstate is the faculty of continuity — it is what lets a digital human know you, and grow a relationship instead of repeating a greeting.
